A Few Million Points: Scan to BIM Getting Started with Revit 2011 Part 2

Scan to BIM is a product from IMAGINiT/Avatech Solutions with a fully functional 30 day free trial that you can use with Revit 2011 (Revit Architecture, Revit Structure and Revit MEP). Details for the monthly public webcast on Scan to BIM can be found here.

Getting started, if you have downloaded the Scan to BIM product (either free trial or purchased, in which case we say thanks!!!!) the first step is to Import your point cloud using the Scan to BIM Administrator (step by step details here).  With that done you are now ready to make use of Point Clouds inside of Revit. Let's use a video to walk through the concepts and details written out below:

Video Step by step:

Step by step:

1. With Revit 2011 Open, go to the Add-ins tab and look for the section called Scan to BIM. We first need to tell Revit which Point Cloud we want to use in the project, to do this select the Setup button.
2. Next, select your project and cloud from the list and choose OK
1. Note: We are now ready to start working with the point cloud, at this point it will not be screen. We also may not be sure of the orientation, if this is the first time you are working with the point cloud follow along the next steps, if you have already done the setup and worked with it before you can skip ahead and start working like you were when you left off.
3. From the Tools pulldown, choose Outline PointCloud. This will place a "box" around the extents of the point cloud using model lines. From this we can get a sense of where this is placed (based on the point cloud orientation and the Revit model). Choose OK, from the pop-up.
4. Next from the Tool pulldown, choose Create Sections. This will prompt you for the number to place along the X and Y axis, as well as the depth of the section cut.  This helps us to understand the Z heights and how this relates to the current levels. Choose Ok.
5. Select one of the Section Views that were just created to open
1. If the level lines are not shown or off the screen, you may need to open an elevation view to extend the level lines to run through the box created in Step #3 above.
6. With the Section View open, select the Update View button and set the decimation to the lower end (to the left) and choose update. This will take a brief moment and update to show the point clouds in the Section View.  

This gives us enough detail to understand where the Point Cloud is placed in relation to the X, Y & Z offset and compare to the Revit level lines. From here you can decide whether the levels need to match the point cloud (which you can use the reference tools to adjust the levels to match the model) or measure and within the Scan to BIM Administrator override the offset values (that is move the X, Y and/or Z value as well as the rotation of the point cloud) for a permanent change. 

Following along with the video we are using the Reference Point tool to pick a point through the point cloud and using the built-in modification tool ALIGN to match the level lines to the locations within the point cloud based on interacting with the points. 

This initial time it takes to go through the 6 steps above, typically only has to occur the first time you are working with the data as you get oriented with the point cloud. After this, you can just use the setup button and then update your working views and move on with the reference tools and geometry recognition for your Scan to BIM conversions. 

Feedback is great and if you have a specific workflow or Scan To BIM question take a moment to share in the comments.

Scan to BIM is a product from IMAGINiT/Avatech Solutions with a fully functional 30 day free trial that you can use with Revit 2011 (Revit Architecture, Revit Structure and Revit MEP). Details for the monthly public webcast on Scan to BIM can be found here.

Getting started, if you have downloaded the Scan to BIM product (either free trial or purchased, in which case we say thanks!!!!) the next step is for you to get started using your own point clouds.  Let's try doing this with a video to walk through the concepts and details written out below:

Video Step by step:


Step by step:

1. Using the Scan to BIM Administrator (Start Menu  IMAGINiT Technologies  Scan to BIM Administrator) you will need to import your point cloud using the file format(s): .pts/.ptx/.fls/.fws (new as of v1.1)
2. Start by clicking the connect button in the upper right, which creates a connection to the database. Existing point clouds that have already been imported will be shown in the list at the bottom.
3. To add to this list, start by choosing the Import Cloud button.
1. Browse to the point cloud, select and choose OK
4. Adjust the name, units and color options as needed
5. Press the Pre-Scan button and when completed press the OK button.

Note: The time for the initial import process varies from a minute to longer for larger, more complex scans. Once completed you will receive a small dialog that lets you know the process is complete.

The Import is a one-time process that you use to take point cloud scans and convert to use for Autodesk Revit to Visualize and Interact inside of the Revit design environment (both Project and Family level, Concept Mass Family).  In the next post we will be covering some more details about the workflow once you get a scan imported and how to use with your own templates.  

Feedback is great and if you have a specific workflow or Scan To BIM question let us know in the comments.

A Few Million Points: Laser Scanning Point Clouds and Revit

At Autodesk University 2010 we launched the product, Scan to BIM, and since then have delivered some minor updates and the next release is just around the corner. With the dust from the merger between Rand, IMAGINiT and Avatech now settled outo it is time to get back to writing.

This month Matt and I wrote a column for Structural Engineering and Design which covered scanning at a high level. Let's get this started by answering some of the common questions that come up about the product and then move into some other detail.

• Question 1: What version of Revit does Scan to BIM support?
• Answer  1: Revit 2011 (Architecture, Structure and MEP), be sure to download service pack 2

• Question 2: What file formats can I import into the STB product?
• Answer  2: At this time you will need the industry standard formats .pts or .ptx
• Update: Version 1.1 adds support for FARO formats: .fls & .fws

• Question 3: In some of the presentations you have shown the current state of the art process, without Scan to BIM, can you share this?
• Answer  3: Sure, but I do not take credit for the workflow. This comes from people like yourself doing this today.  Parts of this were also talked about at the last SPAR conference (which if you work with scanning data, would be a great one to attend).  The process is to take the scan data from the hardware and get this to a Revit model involves anywhere from 2-5 pieces of software that range in price from $3,000 - $30,000 USD.  

• Question 4: Does my Revit file size increase when I use point clouds?
• Answer  4: No, if you have a 250MB Revit model and use a 5Gig .ptx file the Revit Model stays 250MB.  With this approach the point cloud resides in a database and Revit will push/pull the data it needs to display and interact with. 

• Question 5: I see you have a trial of the Scan to BIM software, can I use my own data instead of the sample dataset you provide?
• Answer  5: Short answer, Yes.  
• Answer  5: Long answer, leading up to the launch of the product there was a small pool of people we found that were actually doing Scan to Model conversions and we wanted to make this as straightforward as possible to the general Revit users that would be new to this process. So we limited you to the sample dataset we provided and in the first few days, this was the #1 complaint and so we removed this limitation and sent a note about this out to those who had downloaded the trial to update to the new version.  Since that time you have been able to use your own .pts/.ptx files within the 30 day fully functional trial (with no limitations).  One last item, which we found two weeks ago was the automated e-mail that goes out with the trial authorization which after our update still said it was limited to the sample dataset that we provide (even though you could use your own data).  We kept wondering where this question was coming from and after some sleuthing, found and fixed the culprit. 

So there are some of the top questions we get about Scan to BIM.  In the next few posts we will answer more as well as offer some more insight on usage and how to's.  If you have a specific question, workflow or Scan To BIM question let us know in the comments. 

#YearinReview What did you ship/complete in 2010?

Seth brought up a good exercise on writing out the items you shipped in 2010.  This recognizes in one spot the different items that I am proud to be a part of.  For my adaptation, shipping will be projects (software and business development, writing, speaking or life events that stand out or related):

My 2010 List:

1. Event Switch to MAC platform (had been straddling the fence prior)
2. Launch Scan to BIM, point cloud integration with Autodesk Revit 2011 (Laser Scan to BIM)
3. Launch 100 Percent, 4-in-1 Percentages Calculator for iPhone and iPod devices.
4. Launch Fun for Kids: Activities for Your Family, Activities, crafts, games and entertainment ideas for kids of all ages for iPhone and iPod devices.
5. Launch Avatech Utilities for Revit 2011, includes 11 utilities in the full package for Revit Architecture, Revit Structure and Revit MEP with 3 entirely new tools and user interface adjustments to each to streamline usage.
6. Event Revit in the cloud, private Revit clouds and working with hosted solutions. The Autodesk University presentation brought lots of great questions and showed a rapidly growing interest.  From the mainstage to sidebar conversations the discussion of "cloud" technology was everywhere. More on this in the future...
7. Co-Author Introducing Autodesk Revit Architecture 2011 with Pat Davis, Charlie Busa, Steve Stafford and Beau Turner.

I did not do all of this myself... far from it. Thanks to everyone involved in these projects and for readers, users, volunteers, beta testers, colleagues, marketing, paying customers and more that made these projects happen. There were additional private development items that cannot be mentioned :\ and another twelve to fifteen projects that were started and underway but were not launched in 2010 and as Seth said "If it doesn't ship, it does not count".

The other reason I bring this up is that when I am involved in launching or development of projects this blog goes quiet. This space has not gone dormant, it means that I do not want to spill the beans/excitement pre-maturely and I am working out how to get past this flaw. ;)

Onwards and upwards for 2011...

Revit Model Review - Sharing Checks Quick Tip

Got a nice check file that you have created and now want to share with others in the office?  Maybe you have one you want to share with the world?  Either way if you have a check file and want to share it, others will need this quick tip to use it.

Check Files themselves use the .bcf file as their extension and by default are stored locally (default path: C:\Program Files\Autodesk\Model Review 2010 for Revit 2010 and C:\Program Files\Autodesk\Model Review 2009 for Revit 2009.

The file that controls and shows this is the drop-downs and pre-defined flyouts is the .config file located in same directory as the default Check Files.  Actual filename is: ModelReview.config).  To add to this, use the Manage->Profile->Edit option.

Autodesk Revit Model Review - Check file?

In this post we are going to talk about what exactly is a check file

When you first install Model Review there are some example check files that ship with the product to help you get started.  For Revit 2009 users there are 4:

• Revit Modeling and Energy Standards (checks built around the premise in this whitepaper)
  
• GSA Template Standards (based around using the Autodesk provided GSA Revit template)
  
• Firm/Project Standards-Minimal (some of the common items people asked about checking for)
  
• Firm/Project Standards-Extended (some items people had asked about checking for)
  

For Revit 2010 there is an additional one called:

• Content Standards (based around some of the things that people are concerned with in their .rfa family files)

Autodesk Revit Model Review - Whats New

Today marks the release of Autodesk Revit Model Review, formerly Avatech BIMreview and it is packed with extra goodies making this into an even stronger product.  This post is focused on what is new inside of this release or changes from the prior BIMreview product.  For starters Model Review is not sold separately, it is only available as part of the Subscription Advantage pack, to get this login to the subscription center and download.  There are two versions available for use with all flavors of Revit (Architecture, Structure & MEP); one for 2009 and the other for 2010 (both support 32 & 64 bit).

What are some of the new features that this release offers?

Revit Utilities - Silent Installation

If you are using the Avatech Revit Utilities there is an extra feature available to help you deploy this on your network for multiple users.

To do so use the following steps:
1. Download all the Avatech Revit Utilities (the .executables) into a centralized folder that all your users can access

2. Edit the “Avatech Utilities – Client Silent Install.bat” file to provide your user accessible network path (replace the section that says YourServerNameHere with your correct path) and save (available to download here rename from .txt to .bat)

3. Add the routine to your users start-up batch routine (may need IT to help you with that) or have your users manually install by distributing the .bat file.


This will install the ARU's for 2008, 2009 or any combination thereof. In the event you already have these loaded it will update/overwrite the previous one to use the new build.

The silent installation option is available starting with the following build numbers:
Change Case: Version 1.0.3032.25223
Earth Connector: Version 1.1.3054.15402
Revit Content Browser: Version 1.1.3086.36336
Room Renumber: Version 1.1.3066.26735
Door Mark Update: Version 1.0.3062.25810

Revit Extended - Update

Thanks to some great feedback the Avatech Revit Utilities have been updated to include changes for the following:


1. For those on a 64 bit OS, the new builds will now support that.

2. For those without RAC but who have other Revit flavors (ex. RST, RMEP) installation will now complete for you.

If you were having any trouble with installation please re-download and give the latest builds a go. If you are not sure if you have the latest build you can compare the build numbers against those on the site link above.

Revit Extended

If your working with Revit and finding a few minor items you would like to add or automate to your suite of tools then chances are favorable that through the Revit API this could be accomplished.

I mention this because over the past few years since the Revit API was released our development team has been actively developing tools, both large and small and today we are releasing the first round of free public tools for you to use. These tools come from requests by our Revit implementation/services team, trainers and of course folks just like you.

So without further typing here are todays 5 Free Revit Utilities:

Room Renumbering - allows you to renumber or insert rooms in a sequence

Door Mark Update - to make the door mark match the room it swings into

Change Case - for those who would like to keep a common theme/style on items like view and room names UPPER CASE, lower case and Title Case

Revit Content Browser - this tools will open up inside your revit environment and allow you to download content directly from popular industry locations. The main window currently goes to RevitCity for this release and allows you to review the content you would like and organize it by name and folder location when you download.

Earth Connector - a new update to an existing toolset that now allows you to now work with 4D (time and phasing) from Revit for use in Google Earth.

These work for the Revit 2008 suite of products (Revit Architecture, Revit Structure and Revit MEP) and have been tested on Windows XP and Vista.


Take a moment to download and use, for any feedback send an e-mail to: devfeedback (at) avat.com

Matt has spent a good bit of time working on these and I appreciate him leading this charge, the next round of tools are under development now. If you have a particular tool or need for Revit development please let us know how we can help.

A press release of these tools is available here.

Viva La Revitlution... :)

Return from Autodesk Dev Camp

We are back from the AEC-DevCamp in the Boston area (Wakefield, near Waltham). After two weeks in a row of conferences I am a bit behind and need to run through my inbox to get it "clean again". This conference was a good mix of development (for both AutoCAD and Revit platforms) and a section for business development. www.autodesk.com/AEC-DevCamp

I was fortunate to attend with 7 others from our Software Development Solutions Team and enjoyed the face time with each of them (we are all is separate cities across the US). This week also allowed a few spare minutes to tweak some soon-to-be released Revit API utilities and a new one created on the spot based on another attendees request.

We are compiling a list of the applications we will be releasing soon (in addition to the Avatech Google Earth Connector for Revit/AutoCAD platforms). If there is something you have been wanting to see developed on the Revit platform please drop me an e-mail so we can add to the list for possible future development.

Happy API hacking...
