Re: Improvements to Onshape - September 19th, 2025
I'd like if any of the 3 "planes" of a MC could be used, anywhere a MC is referenced. Either as a sketch plane, or a mirror plane, etc. Limiting it to the XY "plane" of the MC is annoying, IMO. Thanks.
Re: Improvements to Onshape - September 19th, 2025
Easy enough to add explicit MC to any of the main part CL (or directly in the assembly)… You can just create an implicit MC at the origin on the fly in any of the 3 axes so not sure what the big deal is…
I don't work a lot with symmetric assemblies so this hasn't been a huge issue personally but it looks to be nicely implemented!
Named section views in drawings are going to be a lot quicker to setup! Now we just need the ability to control the "regions" that are cut when using multiple section planes!
Also pretty excited to not have to reload the whole render studio to change configuration!
Re: Improvements to Onshape - September 19th, 2025
After seeing all of the strange cases that had to be considered with Assembly Mirror I can understand why it took as long as it did to happen. It's a lot to wrap my head around. Glad it's finally here though and the implementation is as thoughtful as ever!

Yes, this has made my day—mirror in assembly. Looks great, and I can not wait to use it. This should hopefully save days, if not weeks, of work per year.

Mate Connectors are Planes
Mate Connectors are Points
Mate Connectors are Coordinate Systems
Mate Connectors are Directions

Correct we are not flipping thread tags in the hole feature but if you model threads it will.

It's convenient that implicit MCs work, but I agree with @david_littlefair373 's basic point. We need a default way to reference the origin and/or the non-existent default datums of an assembly.

True,
Having the option to include MCs at the origin by default would basically solve this.
The section view is actually more of an issue. I'm not sure why the section tool doesn't allow implicit mate connectors! Especially since you can snap the section point to any implicit MC locations after it's been created! If you don't have a starting point you first have to add an explicit MC (at least you can use the right click and add to instance shortcut), which is pretty dumb… If mousing over the origin gave you the option to pick one of the directions to start the section I would think it would mostly solve the issue…

Haven't had a chance to watch yet, but @GregBrown has a detailed look at Mirror in Assembly:

RE default planes:
The only issue I can think off is if you have "stuff" that make selecting the origin tricky but hardly a difficult process…
Adding the option to save an assembly "template" would allow users to add 3 default MCs on the origin and solve this (and other requests…)
