Draping question

peebo22

Hi,

I draped these edges to the TIN-mesh and my question is, can I somehow remove them if I want or are they now connected to the mesh? Because when i try to remove one edge, mesh breaks.

Is there a possibility to make them as group?

When you Sandbox Drape geometry the receiving container is modified with new intersecting geometry/edges.
So the draped form is then an integral part of the mesh.

To keep 'draped' edges separated from the mesh you need to look at something like my ExtrudeEdgesByVectorToObject.
[Part of my Extrude Tools set http://sketchucation.com/pluginstore?pln=ExtrudeTools ]
Select then extrude the draped-object's faces/edges down in blue [z] axis [use Shift to constrain], pick well below the mesh and the extrusion will be trimmed back at the mesh surface.

You then need to leave the extrusion within its group, edit that and select/delete [by fence] to leave just the edges lying on the mesh-surface...

Then you will have a draped set of edges overlaying the mesh but not combined with it at all...

Thanks for answer, but I don't think it's a good way...
It's too heavy, so Sketchup crashes.

I tried one small lake/pond with your instructions (moved it down with z), but I don't think this will work...or I didn't understand.

It looks nice with normal drape, but it's sad that they are not own group.

You must delete unwanted vertical faces [by fence] ?
