Revit 2018: AutoCAD points not appearing from surveyor's file

[drubinoff]

Hi, 

My site surveyor sent me an AutoCAD file containing elevation points. I want to use these to make a topography. Unfortunately, when I link the file in Revit, his elevation points do not appear. I can see the text associated with his points; it's the AutoCAD points which don't appear. Supposedly the way to fix this is to make Proxygraphics set to 1 in the AutoCAD file; however, this is already so.

Help?

The CAD file is flatten and cannot be used to generate a topography. Ask him to generate a point file (CSV or TXT format), or export a DWG with the actual elevation of points intact.

Hi @drubinoff, 

Can you tell me if the post above has resolved your issue? Thanks!

Revit can't read civil point blocks and neither can Autocad unless you install the Civil 3D Object Enabler.

Once installed you need to open the file in Autocad and then edit the point block so the cross hairs are just lines then update all the blocks.  From there you will be able to see the crosshairs when you link the site file into Revit.

Pain in the ... method but it was the only solution I have found as Civil folk usually won't do anything on their end to make exporting work better for Revit folk.

Hi,

The way I solved this was to open the surveyor's flat CAD file in AutoCAD, edit his block containing the AutoCAD points, add a pair of lines to create a "cross-hair" on top of the point within his block, and then save it. I updated the linked CAD file in Revit and then placed topographic points in Revit on each of the cross hairs and set them at the elevations tagged in the survey.  

I followed this video for relocating my Revit survey point and base points so that I could set the topographic points at their written elevation heights. https://www.youtube.com/watch?v=JcAhhURbNKE

So how's that going to work when you have +4000 points?
