Getting your point clouds / laser scans into Revit has changed slightly, here are the steps you need to prepare them.
Steps To Consider Before Importing Into Revit:
Review whether you need to break the scans/point cloud up or partition them off in a meaningful way.
Ex. By Floor, By Wing, By Key Sections
Resolutions - Consider a hi-res and a low-res version of the same scan (higher vs. lower decimation)
Makes for working in Revit faster when higher resolution data is not really needed.
What kind of modeling accuracy are you attempting to get
Geometry - Profile Walls (will these all be 90 degrees and test that deviation is "not too far off"
Geometry - Create walls with slope to match the point cloud
There are many more items to consider based on your specific needs but these are a few of the more general items to consider and think about.
To get these models into Revit, you will typically generate or receive one of the raw point cloud formats, these include:
Start by selecting Insert Point Cloud from within Revit:
Browse to your Point Cloud file (assuming you only have the raw format type as shown above) and choose RAW formats from the file type dropdown:
After picking your RAW format, you will be promted with a pop-up called Point Cloud File Indexing. Adjust any settings needed (ex. Import Units, File Location, etc...) when ready pick the "Start Indexing" button.
This dialog will continue to run as it converts the Raw Format to a binary indexed file (usually a smaller file size that is quicker for Revit to use) of a .rcp (project, all scans together) and/or .rcs (individual scans where applicable).
Note: This will take some time to convert, from minutes to hours depending on the file size. In the meantime you can continue to work within Revit until this is ready to insert.
When complete we can insert this into Revit, using the Insert Point Cloud button:
When inserting the first point cloud, you have three options for positioning placement:
Auto - Center to Center
Auto - Origin to Origin
Auto - By Shared Coordinates
Typically you will use Center to Center. Review based on your specific needs for correct insertion/adjustiment as needed.
After you place the first point cloud, if you have another to insert you will be given a fourth option "Auto - Origin to Last Placed".
Using this, as the name implies, will insert the Point Cloud based on the insertion placement of the last point cloud. This is useful as long as your point clouds are all using a common origin point, if they are not you may need to manually adjust the placement.
The tools and processes for laser scan / point cloud conversions to usable model geometry continues to get easier as the tools mature. One particulary tricky item is Pipes in Revit MEP. In the IMAGINiT Scan To BIM product (get your free trial here) there are many ways to create pipes (automatic, think easy button or manually one by one as well as tools to go through and do QA (Quality Assurance)/QC (Quality Control) but there is another often overlooked tool called "Adjust Pipes" that can be really beneficial between the two stages above.
In Revit, the Pipe geometry must have the center lines overlapping for them to clean-up. While this makes sense when desiging from scratch, it wreaks havoc on Scan To Model conversion projects as they are quite often slightly off from crossing center lines. Below is an example of two pipes that were created, their center lines are just slightly off and need an elbow between them.
Using the IMAGINiT Scan To BIM tool Adjust Pipe, you can select both pipes and be prompted with options for the best fit. In our example we could move the pipe slightly or adjust the pipe rotation from the far endpoint for a smaller overall adjustment as shown below.
Once we have the centerlines adjusted we can now trim/extend the pipes to create an elbow.
(Note: The point cloud is using an alternative coloring scheme in Scan To BIM based on elevation height, makes this easier to visualize when working with a complex point cloud based on the z axis elevations).
For a better example of using this tool, check out the video below and give this a try on your next project.
This one is a goodie that we want to share because it is a huge time saver. If you have not seen the latest release of IMAGINiT Clarity then you are in for a treat. Previously to use the Task Automation features (not familiar with what these are, check out this link) you had to use a web browser. Now you can kick that task off right within Revit and here is how you do it:
With your Clarity project model open in Revit, you have a new toolbar available that looks like the following:
Look for the Launch Task button and click it (see below):
All available tasks for this project as shown in the drop down (see below).
Select a task that you would like to run, in our example "3 - Generate PDF Sheet Set" and click OK to run.
With this latest release you no longer have to leave Revit to kick these tasks off, keeping you focused on your work and letting Clarity help you to work smarter.
This is one of many new features in the latest release. Don't have Clarity yet, contact your IMAGINiT Sales Rep for more details or to schedule a demonstration.
Our Scan To BIM dev team is looking for a few one-on-ones with customers this week who have Revit experience and point clouds with pipe and/or plant data to sit with us via Webex to review a new feature with you for feedback.
EDIT: Thanks all, BETA period for this release is now closed. Stay tuned for future opportunities.
If you fit the bill we have amazon gift certificates for those we meet with as our way of saying thank you (and of course making Scan To BIM an even better product). Interested, E-mail Me.
Requirements: Revit 2015, Existing Point Cloud with Pipes and/or Plant Data (already recapped into Revit). This should take 35 minutes to complete.
By now you may have heard about a "new release" of Revit that is being called "Revit 2015 R2". This release of Revit adds new features and functionality to Revit 2015 and was released at the same time as a new extension for Revit, Autodesk Site Designer Extension for Revit 2015. The first thing you have to know about the R2 versions of Revit (Revit R2, Revit MEP R2, Revit Architecture R2, Revit Structure R2 Revit LT R2) is:
You have to have an active relevant Autodesk subscription to access the updates. If you have Revit 2015 but your subscription lapsed, you will not be able to get to the update and extension.
That primary piece of information is followed very quickly by this one (call them #1a and #1b):
The R2 release of Revit is fully compatible with regular Revit 2015 software products - the file format did not change.
So... how do you get these updates and enhancements and what can they do to your Revit? I'm glad you asked. To access the downloads, you need to log into the Autodesk Subscription site (subscription.autodesk.com) and find the link to get to your available Product Enhancements. Here is one of the places you can click:
From there, you should be able to scroll down and find links to download the two new enhancements:
The Revit 2015 R2 "application" installs like a service pack - it modifies your existing installation, it does not need an uninstall/reinstall process. (yay!) So what does it add? Well, the improvements can be categorized into three categories, Power, Performance, and Productivity.
Share more accurately predicted energy performance information in custom dashboards with Project Solon integrated into Revit.
Use existing geometry in a linked IFC model as a reference for dimensions, alignment, snapping, and hosting of some families in a Revit model.
Troubleshoot models better with the Reveal Constraints mode making all dimension alignment constraints in a view visible.
Explore visual programming with the Dynamo interface for computational design which now installs with Revit so you can more easily enhance and extend the power of the Revit API.
Edit and regenerate complex toposurfaces, subregions, and building pads.
Get better performance of the energy analytical model in Revit, with Revit R2 using less memory when analyzing large models.
Experience faster updates to views that contain multiple instances of families.
See faster display of Revit links within views.
Work in perspective views, making quick adjustments without having to change views with some modeling capabilities now available in perspective views.
Save more time by editing multiple wall joins together
Find content more quickly with Search capabilities in the Type Selector and all drop-down lists.
Navigate PDFs exported from Revit more quickly with hyperlinked views.
Experience easier interaction with structural elements through user interface improvements.
Improve productivity with more streamlined Rebar modeling and shop drawings creation.
The full list is too large for me to want to place in this blog, so here's a link to a PDF with all the specifics:
Now what about the Site Designer? If you were familiar with EaglePoint's SiteWorks product... well... you know what this extension is all about. Autodesk acquired that technology and is distributing it under this new extension name. Click on the image below for a full size version of the Site Designer Ribbon:
And here's a quick list of what you'll be able to do with this extension:
Report and schedule areas, volumes, and cut and fill volumes to better understand the impact of site design changes on requirements to move or add fill.
Iterate conceptual designs and create more realistic visuals of the building site by incorporating grading features directly into the Revit model.
Better communicate conceptual design ideas about the building site to engineers who can then complete the detailed site design using professional civil engineering tools like Autodesk® AutoCAD® Civil 3D® software.
Share the appearance of site plan designs for better communication with everyone involved in the project, including owners, architects, designers, planners and civil engineering firms.
Share a site model between Revit and Civil 3D through Land XML files, improving collaboration between architects and engineers working on a project.
More quickly add design elements to your site such as berms and drainage swales, minimizing the time required to mass grade a site and to try alternatives at the design development stage.
Special terrain families within Site Designer provide you with parameters that control widths, cut and fill slopes and other projection settings.
Locate hardscape components such as streets, intersections, sidewalks, curbs and walls that can follow the existing terrain and have controlled elevations and slopes - all while the toposurface is automatically maintained.
There's a lot of information to absorb here - hopefully it is enough to get you informed and know if you want or need either of these recent updates!
Welcome to part 1 of a 4-post series by IMAGINiT's Veredith Keller on Revit Adaptive Components! Veredith is wicked awesome and I'm sure you'll enjoy. So without further ado, here is the first post leading into Adaptive Components... Adaptive Points.
Adaptive points are created by modifying reference points. The geometry drawn by snapping to these flexible points results in an adaptive component. Adaptive components can be used in pattern panel families, adaptive component families, conceptual massing environment, and projects.
In this blog post we'll show you how to create by using Adaptive Points, starting with a Generic Model Adaptive family. This is the first step in getting you started. Here's a quick tutorial on how to create your first adaptive points and component:
From the application menu choose New> Family.
Choose Template File, Generic Model Adaptive.rft.
From the Modify|Place Reference Lines tab>Draw panel, pick Reference>Point Element
From the option bar>Placement Plane dropdown, choose Level : Ref. Level
Place 4 Reference Point Elements.
Select all 4 Reference Points.
From the Modify|Reference Points Tab> Adaptive Component panel, pick Make Adaptive.
Now all 4 Reference Points are Adaptive. You should notice a change in graphics and numbers next to the points. These numbers came up in the order that you placed them.
If you need to change the order of the numbering you can pick on a number, change it, and the others will adjust accordingly.
Example: change 4 to 2 and you will now see the others numbers have changed automatically. Change 2 back to 4.
Next, you need to create a surface off of the points. Please note that it is very important to work on the correct work plane when creating surfaces.
Extra note: each adaptive point has an X, Y and Z work plane.
To start creating the surface, make sure 3D snapping is turned on and draw a Reference Line from point to point. To do this, pick the Modify|Place Reference Lines tab>Draw panel>Reference>Line button.
From the options bar turn on 3D Snapping
Draw a line in the order of the reference point numbers.
Now we need to test and make sure that the Lines are attached to the Reference points by moving the Points in the Z direction.
Pick on a point and drag the blue Z arrow up and verify that the reference lines move with the point. Then Undo to bring it back.
Pick on one of the Reference Lines. Note: when you choose one Reference Line all 4 are chosen automatically.
From the Modify|Reference Lines tab> Form panel, pick on Create Form>Solid Form.
You will see a choice of Solid of Surface. Choose Surface.
Save this family.
Now, start a new project and draw a wall. From the quick access toolbar pick on the Default 3D View button.
Open the Adaptive family and from the Family Editor panel pick on Load into Project.
Notice that the Placement type is Place on Face. You can also make associations to specific levels in the model by changing the Placement Plane option from the options bar or you can also pick on the surface of the wall.
In this example you will pick 4 pick points. Note: this is the number of adaptive points made in the family.
1st pick will be on Placement Plane: Level 1.
2nd pick on the surface on the wall.
3rd pick top midpoint of the wall.
4th pick will be on Placement Plane: Level 2.
If you change the height of the wall or move the wall the points will change with it. You can also tab to the points and drag the XYZ arrows to change points to another location.
Here's another example:
Make the Placement Plane Level 2, changing it from the likely default of:
... and make sure that Place on Face is selected
1st pick on Bottom left of wall
2nd pick is on Placement Plane
3rd pick is on Bottom right of wall
4th pick is on Top midpoint of wall.
These are the first steps on making Adaptive Components. The next blog post in this series will cover using formulas with Adaptive Components.
Revit's inability to snap or manually align annotation object have long been a frustration to those that have adopted Revit. Jordan Musset shares a little secret that he likes to use with sections for precise placement.
Sections can be a little finicky in terms of being able to place them exactly where you want them. A technique to place them where you want them is as follows. If the section is to be placed exactly in the middle of the expansion joint, follow these steps.
Sections will not use detail lines as a reference and it is difficult to move sections into place after they have already been created. Mostly because the snaps don't always pick up pertinent references within them. Draw a reference plane that is placed specifically where you want the section.
After that, place the section with two clicks, making the two clicks the beginning and end reference of the reference plane. Now the section is placed exactly where intended. Also recommended, delete the reference plane and pin the section in place.
This week Jordan Mussett tackles the issue with text labels in hosted content.
There is a short list of families in Revit that you will need to host to the face of either a ceiling or a wall. A good example of this is smoke detectors. Depending on where they are, they can call for either a vertical face or a horizontal face. The problem comes in when there is a text annotation buried into the family. The one to the left below is hosted to the wall at 8'-0" off the floor, the one on the right is using the face of the ceiling at 9'-0" off the floor.
If this text is to read the same direction, there is some work that needs to be done in the Family Editor. First, save this family using a different name if you would like to preserve the integrity of the original or if you aren't 100% sure it will work, it is good to have a backup. Next, copy the Generic Annotation that is there and rotate it 90 degrees. Align and lock to the vertical Reference Plane. The original label us up-side-down because the intent of this family originally is that it be placed on the ceiling, the generic annotation label will right itself in the respective views in the project.
Next, visibility instance parameters are needed to display one or the other depending on if it is using the wall face or the ceiling face.
Load it back in to the project. Change the two original ones to the new family just created and set the instance visibility parameters.
