Vectorworks is closing my contours

Recommended Posts

I've successfully imported polyline contours from AutoCAD and created a Digital Terrain Model. However, where the contours run off the boundary of my project, Vectorworks is closing them with the nearest contour of the same elevation. This creates a vertical "wall" of terrain/contours at the edge of my site that I don't want. (see photo). 

 

I assume it does this because Vectorworks places 3D Loci on top of the polylines and uses the loci, not the polylines, to generate the model. Is there some way to avoid this, or some way to correct it? I tried to "Edit Site Model" and then slice out the connecting portion of the contour, but it seems to revert when I exit the Site Model editor.  What am I missing?

Right click on the DTM and select edit crop. Delete the extg crop if there is one and draw a new one that is within the extents of your DTM. This will clip out the closed part of the contours.
