Help using the draping tool please

[klozza2808]

I am currently modelling a site for an upcoming project, but am having issues draping my sit plan onto a face. When i drape random gaps appear in my lines that are not there on the imported AutoCAD drawing. I have messed with tags and grups but nothing seem sto be working. I attached screenshots and my model and some hwlp would be greatly appreciated!!

The plan imported from AutoCAD that you are trying to use for Drape already has a lot of problems (maybe this is how it was drawn).

Check the dwg file and make sure the plan is drawn correctly.
