I have just created a somewhat complex part (several extrusions and material removals), it is the straight part. Now I need to draw the left piece, do we have a simple solution to make it? Otherwise I'm going to copy this part, and take each of the functions and reposition the sketches.
@benoit.lf and @pl gave the method for creating a new piece.
If you want to create a symmetrical configuration of the said part, you have to follow these steps:
view1-create the part and put it in an assembly (here, I created a virtual part in an assembly)
view2-mirroring the assembly by selecting a reference face and the part and -->
view3-select 'create symmetrical version then -->
view4-select 'create a new derived configuration...) then -->
view5-no need to select what you want to copy in the symmetrical part since it is in fact the same part and you validate
view6-we see the 'Function Symmetrical Components' folder in the original part, we can use the symmetrical part by activating the derived configuration 'DefaultSymmetry'
Thank you for your solutions, but I'll come back to the 1st proposal: Insertion/Symmetrical part. I can't find this function, in the insert menu I have repetition system or part. Not the symmetrical part function.
