Mirroring in general is more complicated that it SHOULD be.
I have a part model that I need the opposite hand for. The most obvious way of creating this mirror model would be to go FILE/SAVE AS/MIRROR. The only problem is that you can NOT choose the plane to mirror from. WHY NOT? There is absolutely no reason this crucial step shouldn't be included.
There is a work around that involves extra un-needed steps.
This includes going into an Assembly and creating the mirror from this. Within Assembly it does allow you to specify the mirror plane.
I have followed PTC's specific directions to produce my needed mirrored part.
I specified the mirror plane from my original part (I also tried this with the Assembly mirror plane)
I am very happy with my result. See picture below (New mirror is in green)
The satisfaction fades however as I see that my model is precisely the way it mirrored before. See picture below.
After the ensuing frustration I discovered that I could rotate my part so I was able to get the correct orientation. See picture below.
When I go back into Assembly after rotating the part I see that it displays incorrect to the view visibility within the part. See below picture
Any idea as to why my Part and Assembly models do not line up?
After this experience I voted up one of the Mirror part with specified plane Idea submissions.
What worries me however is that I have a mismatch between what I can view between Part and Assembly. This could lead to extremely expensive manufacturing results.
I did modify my planes to a World View Coordinate System. My views and Csys orientations appear to agree with each other in my Part and Assembly templates. This is the 1st such anomaly I've seen.
