Some constraints do come across if BOTH references are in the mirrored set. From the help ...
The Mirror command recreates any constraints that have both references in the set of components that you select for mirror or reuse. If the orientation of the new reference is ambiguous, the new constraint is suppressed.
It is logically possible. Solidworks does it great. You can mirror about a global plane and then drag and watch as the mirrored parts dynamicaly follow in all 3 directions. Definatley an ability that Autodesk needs to play catch up on.
Yes but are you going to mirror using a global plane on all occasions?
Since I use a common global coordinate system I would say about 99% of the time.
But SWx can be about any plane or face, I just used global as an example. They have a symertry constraint and width constraint, which inventor doesnt, so its capability is probably based on that technology.
Skeletal modeling using derived parts as composites when references are needed. Most parts have their origin at 0,0,0 and they are grounded in their assembly at 0,0,0. Sub assemblies are also grounded at 0,0,0. Very few mates needed and very few associative sketches. The only exception is when I place standard items from my library, but they are also modelled at 0,0,0 with the global orientation in mind to make it faster to mate them.
I understand skeletal modeling. Have modelled that way for years. But now use the multi body technique. Also have written code to include parameters from the main solid body file, then flat pattern the plates and populate thickness, width and length.
What if your solids aren't centered around the origin. How do you mirror them and keep constraints in the assembly?
No matter which plane I use, if grounding isnt suitable then I manually add the constraints, but its frustrating that there is no symetry or width type mates. Makes it hard when needing to drag things around at the concept stage.
Go to 3min 30 on this video so see what I mean http://www.youtube.com/watch?v=a-dnuZLdsz8&feature=related. To be able to drag and maintain symetry is impossible in inventor because we have to enter an offset value which doesnt update live. Notice also how they have a mirror feature which can be edited, we dont have that either.
Yep agree. Looks like sw are a step ahead here with this functionality. You will find that both softwares will be ahead in different areas. I'd actually like to see the grip snaps in inventor improved for quick conceptual work. You might be out of luck for the next version of inventor for this mirror feature. Unfortunately.
