[Closed] need help about a collapse question

What exactly are you trying to achieve? Which collapse type are you trying to perform? Are you just collapsing all selected objects in a single mesh, or do you want to individually convert them?

of course collapsing selected objects

sometimes collapsed objects’s face is filp

why??

This will combine multiple objects into one edit mesh:

undo "Combine..." on
   	(
   	for eachObj in selection as array do
   		(
   		converttoMesh eachObj;
   		);
   	
   	for i = 2 to (selection as array).count do
   		(
   		attach selection[1] selection[2];
   		);
   	);

This will collapse all objects to an editmesh but will not combine them:

undo "Collapse..." on
  	(
  	for eachObj in selection as array do
  		(
  		converttoMesh eachObj;
  		);
  	);

I’ll have to remember that undo code… always helpful!

use this code:

[left]undo “Combine…” on
(
for eachObj in selection as array do
(
converttoMesh eachObj;
);

for i = 2 to (selection as array).count do
	(
	attach selection[1] selection[2];
	);
);[/left]
