iztok13 Posted September 5, 2012 Share Posted September 5, 2012 Hello, How to project 2d polylines onto 3D terrain (surface) I was wondering if its any possibility to stick a polyline with x,y coordinates, to surface x,y,z coordinates. So i can read z coordinates from poly witch is on surface ? Quote Link to comment Share on other sites More sharing options...
Tiger Posted September 5, 2012 Share Posted September 5, 2012 perhaps using a 3Dpolyline (cmmand 3DPOLY) will help you? Quote Link to comment Share on other sites More sharing options...
iztok13 Posted September 5, 2012 Author Share Posted September 5, 2012 i have existing polyiline and i have to project to surface !! Quote Link to comment Share on other sites More sharing options...
Tiger Posted September 5, 2012 Share Posted September 5, 2012 command PROJECTGEOMETRY then? update: noticed that you have 2009 - PROJECTGEOMETRY was introduced in 2011 unfortunatly Quote Link to comment Share on other sites More sharing options...
iztok13 Posted September 5, 2012 Author Share Posted September 5, 2012 i have civil 3d2012 and PROJECTGEOMETRY doesnt work on my case i dont now why.it works like command but doesnt do anything ? I post a picture of my case. I have triangular surface, and i need to project polyline on surface (Q100). Any idea? Quote Link to comment Share on other sites More sharing options...
Tiger Posted September 5, 2012 Share Posted September 5, 2012 If you turn the model, you can't see the new lines then? When I did it, it was very faint white lines that transferred. And they get projected at the view you are in, so you don't see them until you move the model around. Quote Link to comment Share on other sites More sharing options...
iztok13 Posted September 5, 2012 Author Share Posted September 5, 2012 doesnt work, nothing was projected ? Here is the link of the file if any help http://www.speedyshare.com/x4weF/test-linije.rar Quote Link to comment Share on other sites More sharing options...
Tiger Posted September 5, 2012 Share Posted September 5, 2012 Then I have no idea Hope some brighter mind swings by and gives you a hand! Quote Link to comment Share on other sites More sharing options...
sevdo2000 Posted September 5, 2012 Share Posted September 5, 2012 Try "imprint" command. Draw polyline (line) on solid surface, then use IMPRINT (look in help). Quote Link to comment Share on other sites More sharing options...

JD Mather Posted September 6, 2012 Share Posted September 6, 2012 I have no knowledge of Civil3D, but in earlier versions of AutoCAD - Extrude and trim surface to the intersection and then xedges to extract the edge of the trimmed surface. (change active color first) Quote Link to comment Share on other sites More sharing options...
iztok13 Posted September 7, 2012 Author Share Posted September 7, 2012 Ok guys, I find a solution: 1. existing polyline convert to featuring line from object 2. then this featuring line project level on surface 3. then explode feature line & i get 3d poly yupee thats it Quote Link to comment Share on other sites More sharing options...
Tarannom Posted March 20, 2015 Share Posted March 20, 2015 You can use modify/Edit elevation/Elevation from surface Quote Link to comment Share on other sites More sharing options...
Tarannom Posted March 20, 2015 Share Posted March 20, 2015 But you have to change it to 3Dpoly first. that you can do via modify/Design dropdown/convert 2d to 3d. or simply write convert2d and rest of the command will show up Quote Link to comment Share on other sites More sharing options...
