Split Object Behaves Poorly
-
Hello All,
Just wondering how to avoid a problem I have seen repeatedly. As seen in this image, I took an object and split it in to two parts so that it could be printed. The scale (as I learned here, is 10x what will fit on my printer (1000's of mm)), so I don't believe this is a scaling issue.
I split the object by creating a plane of 0.5mm in width, intersecting it with the object, and then deleting the plane and the intersection lines on the object and doing a bit (not much) patching. The problem starts thereafter.
From there on out the walls are all (bizarly) fragmented, long clean lines are actually broken small segments, I'll get the error message "cannot use push pull or [sic] smoothed walls" (which are not smoothed). To make changes (such as the tabs you see) I have to do a lot of gutting and stiching.
This second image may be diagnostic.... It is the hidden geometry that is automatically generated (the one little side wall is on purpose, for printing, everthing else is just sorta like "wtf" )
What can I do to make this a smoother processes?
Thanks!

Ahhh, great!
I love the fact that there is always multiple ways by which to accomplish the same results.
Thanks kindly!

I usually select only faces which really need to be intersected (and use Intersect Faces - With Selection). The unwanted "hiden" lines can usually be simply deleted, so I use Eraser for it. This is not perfect solution, but usually good enough.

Sometimes SketchUp creates hidden edges as part of its "auto-fold" behavior and then fails to erase them when it turns out the surface actually stayed planar. In such cases you can indeed erase them. An intersect operation may help SketchUp re-examine whether edges actually cut faces, especially the edges of a smaller face inset in a larger one.
But if you erase an edge and adjacent faces also vanish it is a sign that the corners are no longer planar so SketchUp had to use triangles to cover them. No operation other than correcting the vertices to planar can heal this situation.

ThomThoms CleaanUp3 is also good for this sort of thing.
