ProBooleans and lofts, argh!

[kainfury]

Hello!

 

I have a problem with ProBooleans.

 

To explain my problem, here is a simple example (look at the images)

 

What I am trying to do is create walls using Lofts, as shown in the 3Dats book (which is amazing, btw).

 

Step 1 (first image)

 

I have created a wall profile, with some vertices along the left edge. These vertices are used to created decorative bands along the wall. I plan to give these bands a different Mat ID later, and apply a sub/multi texture to it.

 

The rectangle is the wall path.

 

Step 2 (2nd image)

 

Here is the Loft result. You can cleary see 3 edges running along the wall, which have been created by the vertices on my wall profile (spline).

 

I plan to put windows between the 2 pales blue bands.

 

Step 3 (3rd image)

 

I have drawn boxes that will be used to create the window openings. The boxes are NOT overlapping the top and bottom edges, but are very close.

 

Step 4 (4th image)

 

I have attached the boxes together, then applied a ProBoolean to my Loft.

 

Here is the problem :

 

As soon as I substract the boxes from the Loft, the edges disappear! No way to get them back!

 

I've tried to collapse the newly created ProBoolean to a Edit Mesh, stil not result.

 

O've tried to collapse it to a Edit Poly, and triangles now appear on my Loft

 

 

 

Does someone know how I can do a ProBoolean while keeping the edges on the wall?

 

Thanks in advance!

Nice job on the explanation.

 

I am rendering (again? still?) so I can't test this, but from the help it looks like you want the Advanced Options rollout; Planar Edge Removal group and Remove Only Invisible or No Edge Removal.

 

They don't show a picture, but if I understand the description right, it should do your job.

try collapsing/converting the loft to an editable mesh before you pro-boolean

To Mr. Gruhn:

 

Thank you! Thank you! Thank you! Thank you!

 

That was giving me a headache!!

 

Much appreciated!
