Hi guys, when I used the Surface Matching tool "Intersect in Entire model" in skp, a weird thing happened. Though it did split the surface into surfaces, the right side two still stay the same name and lead to connection failure. How come it happened? And how can I fix it? Many thanks!

Can you readd the pictures you apparently tired to upload?

Based on your description, your question seems to be similar to this issue. Please take a look and see if the solution helps. In general, the surface intersection measure in OS works better than the sketchup intersection feature. The response in this question refers to it

Thanks, Julien and rsunnam! That first link problem is what exactly I'm struggling in. But I don't know guys mention about " using the measures" could help solve the issue. I'm new in this forum. Does that mean you should not intersection the model in skp plug-in place? How to do so? Thanks for your kind help.

Yeah, OS App measure works better than Sketchup plugin script.

Load your model in OS App, go to "Components & Measures > Find Measures" and look for "surface matching" under Envelope > Form (it's this measure on BCL). Check the box, click "Download".

Then use "Components & Measures > Apply Now" to apply this measure to your model:

Dear Julien, thanks for your clear answer! I'll try it later.

Is this supposed to work for all surfaces? When I try it, there are still a number of surfaces I have to manually match, even simple ones. Can someone tell me if this is normal (having to manually match some surfaces)?

My experience with it as been that it's indeed not 100% accurate. One problem is how you draw geometry if you use Sketchup. Sketchup has a bunch of rounding errors (one thing I always do is to set the precision to the maximum number of decimals before I draw), so sometimes surfaces aren't detected as being coplanar.
