welding "doubles" vertex

[scherten]

hello,

 

i have a question about 3dsmax, basically i got a building exported from cad to .3ds, and the normal are flipped and faces are detached...

well i can do it by hand in edit poly, but this is a pain since there are tons of objects.

 

so maybe writing a script like this:

apply to selected object

select all vertex

weld selected by distance 0,1

select all faces

flip normals

 

i have looked in the maxscript listener, but i cant figure out how to make the script "generic" to work with every object.

 

maybe someone have a solution to automate this process, because this is a common issue.

 

thanx

The direction of normals depend on how you draw in CAD. If you drew clockwise or counter-clockwise the normals will be based on that. It is a good idea to use "Polylines" in CAD rather simple lines. When you import a DWG or DXF file, the import dialog gives you the option to automatically weld the vertices.

 

Hope this helps.
