Corridor for boundary

[nikoue]

Is there a way to use my corridor as a hide boundary on the excisting or finish ground surface. I wand to have a more realistick 3d model in witch the corridor will always visibleand the fg surface will not cover it

What you need is a composite surface 1. Make a new surface named, say "Composite". 2. Paste you existing ground surface. 3. Paste your corridor surface. 4. Set this new surface to "Rebuild automatic". Any edit you make to the corridor will result in a change to this composite surface.

Thank you.

I have already done this, but i want to do another.

I want to make a hide boundary because i want to see only the corridor and no the corridor surface.

Create a corridor surface and extract the boundary - then use this

[nikoue]

Thanks for the solution.

But i want to know if i can make it to be dynamic if i make changes to the corridor

[neilyj666]

The surface boundary will certainly update if the corridor changes but - and I'm not entirely sure about this - you may need to remove the original hide boundary from the definition and then redefine the hide boundary. I don't have any corridors/surfaces immediately to hand otherwise I'd try it myself....!!!!!

[nikoue]

if you extract the boundary then its a 3d polyline it cant be update

[neilyj666]

Yes - you delete the original 3d polyline that you extracted, extract the new corridor surface boundary and use that as the hide boundary

There is no dynamic method for what you are wanting to do as far as I know.  But the way it is is very fast.
