Hi Michael,
I did "keep separate" which helped a lot.
But now I have issue that I want to join those two objects (extruded side and original model) and when I do the command it seems like it's working but it will not join.
EDIT: found out that the big original object has issues performing booleans with other objects.
I also tried overlaping the objects with 0,01mm but didn't help.
Any idea why it won't work?
I can send you 3dm file but I would like to avoid people doing things for me.

Hi Mr. Yuri,
> Any idea why it won't work?
I can't really tell what you're running into from just a text description, I would need to see the .3dm model file to give very good advice on that.
Sometimes when objects just barely graze each other it can be a problem getting clean intersection curves, an alternative can be to use Edit > Join instead of a boolean. Join unlike booleans does not try to intersect the objects with each other and remove material, Join only glues things together where there are unjoined ("naked") edges.
Another thing to check is if your big original object is a solid or if it has any naked edges.

Hi Mr. Yuri, I sent you an e-mail reply with more details in it but basically the performance is poor with your model because it is structured as a polygon mesh with over 100,000 little flat faces and CAD solids are not designed to work with that kind of high density faceted geometry.
The main thing you would do to improve performance would be to use a polygon mesh modeling program to work with this kind of data instead of a CAD program like MoI.

Hi Michael,
sorry for late reply (have new son and all).
Thanks for thorough analysis and detailed explanation. I appreciate that.
It is however quite time consuming.
I designed the model in a way that I don't join the parts as a model but export all parts as STL (making it sliceable and 3d printable as one piece)
And found out MoI3 cannot handle in timely manner those models.
MoI4 is much better in this application (and I believe in many others) :)
