Hi pafurijaz, this old thread was from before there was a scene browser in MoI.

Now this script isn't necessary because you can use the Scene Browser to do the same thing.

If you want to untrim all individual unjoined surfaces, right click on the eye icon on the "Surfaces" entry in the Scene Browser. Now only individual unjoined surfaces will be visible.

Now click on the selection dot on Scene browser > Types > Edges.

That will select all edges of the current visible objects so all edges of the unjoined surfaces will now be selected and you can hit Delete to untrim them all.


Another way you can do it is by using the detailed object properties selection functions.

For this way, select everything then press the "Details..." button to open up the detailed object properties dialog. In the "Type" section of the dialog you'll see a report on the types of the current selection like "3 solids, 6 open surfaces". Click on the "6 open surfaces" label to narrow selection down to those, then click on the edges label to switch selection to the edges of those surfaces and then you can hit delete.

The properties dialog selection narrowing way doesn't need to fiddle with changing visibility.
