Drape - Prevent merging geometry?

@unknownuser said:
Note: The draped edges will be outside of a group or component context if the TIN is encapsulated within a group or component.
From this I thought that when I selected a group of edges I want to drape - and drape it onto another component that the edges would be generated outside the component. But regardless of what I do the edges appear to always generate inside the component....
-
yup this is strange....
I used to remember this happening once upon a time but then there were bugs with the drape tool in older versions of sketchup... so maybe they changed how things work
One solution for the time being is to extrude the edges you want to drape into a prism, group this and intersect this with the component. If you do this between the group and component the intersection lines generated will be outside either of them...
Forgive me if i'm telling you something you already know.
hope this helps.Dave

You are right, the draped edges are always applied directly over the faces of the faces inside the group/component ! Even if the group is within a group etc etc... The Help notes are wrong !

But I swear I've seen it as described. Then I found it annoying. But now I want the effect. I have tried with SU7.1 and SU 6. Same result.
-
And I started using SU when it was SU6.

That is odd. Tyler Miller said he addressed some bugs in the tool for version 7.0, but if you said that 6.0 works the same way, then that is odd.
Perhaps we are all remembering how the "from contours" makes its TIN in its own group and leaves the contours outside that group? Maybe not....

Has anyone tried with SU 5? Maybe back then it was different (I only used SU free with v5 and it did not have the sandbox tools so cannot remember now).
Often they just forget to update the help center articles.

Unfortunately the drape tool is a .rbs file so it's not readily hackable - otherwise it's a straightforward matter of changing the intersect's destination 'entities' from the "mesh_to_intersect_with"'s entities to the 'active_entities' [which might sometimes be the same thing]...
-
I must be going mad because I really thought I used to be able to do this. And I have not used anything other than SU6 & 7.
