Hi all,
Not sure if I'm the only one who uses chamfers and fillets which needs to be modified later or I'm missing some crucial funcionality in MOI.

I have this cover model and I want to modify chamfer but I cannot do so.

I tried to delete the chamfered surface and extend one wall down and make planar surface with lower face edge, then join everything but I never get the solid again.

I tried the script
script:var gd = moi.geometryDatabase; gd.deselectAll(); var breps = gd.getObjects().getBreps(); for ( var i = 0; i < breps.length; ++i ) breps.item(i).getNakedEdges().setProperty( 'selected', true );
and I can see some edges that are not highlighted, but no idea how to properly remove them to get that thing to solid.

Things like these are so frustrating that I feel like total idiot and really want to break something. Simple thing like this takes me more than 30 minutes trying to figure (and I failed).
Is really MoI only artistic modeler or anyone who uses it for mechanical parts got their models 100% everytime so they don't need to do any alterations afterwards?

Do I have to look for another software if I want do make and modify mechanical parts?

Thanks a lot.
