Nice. That did the trick. My zlibs are in Windows/ and SysWOW64\ . Thanks!

I just updated to sketchucation 2.6.1. Some errors appears when loading sketchup:

Anyone can help? Thanks in advance.

Found the cause of it. Actually its from the stl I have used netfabb to try to fix it. So, the CFace errors are those extra surfaces added from netfabb to make the model water tight. Then only i imported into sketchup and try to clean it. I managed to solve it by importing the stl directly, clean using cleanup, redraw uneven and erroneous faces. No problem after that. Thanks for the replies mac1

Attached is the file:

After some trials, the errors happens when i tried merge faces

@cotty said:

And the question is?

The cleanup seems to delete wrong faces? The coplanar error appears only after the cleanup plugin is used to clean the model.

Hi

I imported an STL file into sketchup 2014 and I am trying to clean the faces with cleanup and it appears to cause some problems.

I am using SuSolid to check whether the model is watertight. Directly after i import, the SuSolid shows no problem with the model. However after i ran cleanup, some issues appear. I am using Sketchup 2014.
