Using Civil3D to increase your Topography resolution in Revit

Luke Johnson

You receive a DWG file from a surveyor, and you need to get it into Revit.  You go through all the usual cleanup steps.  You have purged, scaled, done a write-block, audited.  You link the DWG into Revit, create the topo – and it looks like rubbish.

If your survey data has some severe gradient, perhaps relating to a steep retaining wall on the site, you may find that Revit does not model it ‘smoothly’.  Here is an example

The problem is likely related to Revit’s triangulation method for topo surfaces.  You get weird flat surfaces where things should look much smoother and more organic.

Here is a quick workflow that I have used to add some realism to a survey DWG without sacrificing accuracy (note – this method uses AutoCAD Civil3D, you can download a trial):

  1. Open the survey DWG in Civil3D
  2. Create a new Surface (Right click Surface in the Toolspace – Create Surface…)
  3. Add the objects to surface (can be easier to isolate the necessary layers first).  To do this, expand the Surface node, then the Definition node, then select the Drawing Objects entry.  Right-click and choose Add…  You may want to add Contours separately using the Contours node.
  4. Edit Surface Style
  5. Contours – Contour Interval.  Change contour interval to something very small – I find 10mm works well
  6. Turn on the Contour layers for the Surface in: Surface Style, Display.  Also, set a new Layer to be the ‘layer’ for the Surface Contours (major and minor)
  7. Extract the newly created contour objects (select the TIN Surface and click ‘Extract Objects’).  To make my site look better in Revit, I actually had to export the Triangles as well.
  8. Select the extracted Contours / Triangles and save them out to a new DWG file (you can use write-block or the inbuilt Export command in C3D). You will need to take some geometry from the source file (like boundaries) so that you can locate these new contours in your Revit model.  Or keep them in the same file with the new layers you made in step 6.
  9. Import this new ‘high resolution’ contour plan into Revit
  10. Use these contours to make your topography (select only the appropriate layers when using Import Instance while creating Revit toposurface).
Lots of contours here – thanks Civil3D

The result?  Something with a much more ‘organic’ appearance:

Better Revit surface (Realistic View, Edges off, Subregion applied)

Obviously, this method has a couple of caveats:

  • it will take a bit of processing power, both on the Civil3D side and on the Revit side
  • once you have your high resolution data in Revit, it will mean you are dealing with lots (thousands) of points in the topo – you have to decide if the nicer looking surface is ‘worth it’ to you 

Also, using my Quadro FX580, if there were too many points, my computer would basically just hard-crash to a BSOD – save often!  I ended up switching to software emulation (turning off Hardware Acceleration in Revit).

      A very quick way to export a very clean RVT file

      Luke Johnson

      You may want to do a very aggressive cleanup of your Revit file, getting rid of all Views while retaining all 3D elements as proper Revit elements.  You can use the ‘Save to New File’ function to do this. (Note: when I say aggressive, I mean it – use at your own risk, and be sure to verify the contents of the output file).  Thanks to the revitogbim blog for this tip.

      This is the trick: when you right-click a 3D view, the Save to New File option is grayed out, but when you put it on a sheet – its back!

      Here’s how to do it:

      1. Create a Sheet and place a 3D view on it.  The 3D view has to ‘contain’ all of the elements you want to keep in the new file.
      2. In the Project Browser, right-click on the created sheet and select “Save to New File …” (it will take a while as it collects the elements, then it will prompt you to save the RVT file somewhere)
      3. Open the exported file and Transfer Project Standards for Line Weights / Patterns / Styles and also Object Styles (and anything else you want)

      Views in the resultant file:

         (the following lists are not exhaustive)
        Things that are removed:

        • Design Options
        • Floor Plans – well actually, the only view that remains is the ‘export’ view and the Default 3D view
        • Everything else that was unused or not visible

        Things that are retained:

        • Floor levels
        • The 3D Revit elements that you could ‘see’
        • RVT links if they were visible in the 3D view
        • the Sheet that was exported

        To make things look right, you will probably need to Transfer Project Standards for things like:

        • Line Weights / Patterns / Styles
        • Object Styles

         For my test case, I also turned off all Annotation Categories in the original 3D view, and I scaled it so it would fit the sheet.

        Should a video card for Revit cost $100 or $1000?

        Luke Johnson

        RFO Co-founder iru69 recently (14 October) updated his very detailed post on video cards and Revit at:

        Revit Hardware : Video Graphic Cards

        I recommend that you read this prior to investing in a new graphics card for use with Revit.

        The post even includes an FAQ section – here is a little sample:

        “Autodesk/my reseller/unnamed CAD expert says I should only use “Professional” (workstation/CAD) cards with Revit. But then I read here that lots of people use and recommend “Gaming” cards for Revit. Who is right?”
        Despite what you may have been told, consumer (gaming) video cards can work just as well with Revit as professional video cards.

        “Someone told me that SLI or CrossFire will double the speed!”
        SLI and CrossFire are great for the latest video games, but it’s of no use at all for Revit. At least it’s never been demonstrated. If you want to give it a try, be my guest. 😉

        Native Revit can make PAT files too – you just have find them …

        Luke Johnson

        I previously posted a way to generate PAT files from an exported DWG file.  One of the comments to that post gives a great alternative method – so unique it actually made me smile.

        You may have noticed that when you export a DWG file, Revit temporarily creates PAT files in the export folder, and then it deletes them, just leaving DWG and PCP files.

        To recover the deleted PAT files, you can simply use the program Recuva!

        I’m not sure how well this works for network shares or NAS devices, but it should definitely work if you export the DWG to a local drive and immediately recover the PAT files (before doing anything else).

        Pretty tricky huh?

        A really small piece of Revit pi

        Luke Johnson

        This post was prompted by this from Darren Snook.

        Firstly, let’s see actual pi to a decent level of precision:
        3.1415926535897932384626433

        Can Revit handle high precision pi calculations?

        As a test, let’s use a circle with a diameter of 2000mm (radius of 1m).  Using the above precision, the area should be equal to pi in m².

        Make a new project in Revit, no template, Metric.  Draw a Filled Region with radius of 1000mm.  The Properties Palette reports the area as:

        3.142m²

        Ok, obviously we need to increase the precision of Area in our Revit project.  Into:

        • Manage – Project Units – Area.  
        • Set Units to square millimetres, Rounding – Custom, Rounding increment:
          0.000000000001 (I couldn’t get Revit to accept any higher – it would just say ‘Invalid Input’, which I take to mean “what you’re asking for is a bit ridiculous”.)

        Properties box for the filled region NOW reports:
        3141592.854703690900 mm²
        3141592.653589793238 (same amount of digits from the definition of pi)

        The percentage of inaccuracy between the two?
        0.0000000640165425247805 % (the Revit value is slightly larger)

        This was a value difference of 0.201113897662 mm²

        However, I am prepared to accept the above level of precision, at least in 99.999994% of my projects 🙂

        The lesson?  If you are going to use Filled Regions for areas AND you want good precision, make sure you adjust your Project Units accordingly.
