Hi,
I started reverse-engineering the base of a rat trap as an exercise, to align myself with the way things work best in FreeCAD. FreeCAD looks beautiful to me so far. I am mainly using Sketcher with Part Design.
Now I am failing to apply the PartDesign Mirrored tool which responds with an error "Recompute failed! Please check report view."
The idea is to mirror a feature, or features that make the small double bearing protruding from the center of the main body.
The mirror plane should be "latchBearingMirrorPlane"
I can see what the problem could be. There might be an issue with mirroring that key hole feature "PocketCenterBearingHole" (that also cuts into the base) while the features that this cuts into are not yet mirrored.
I don't want to push things too far. Is there perhaps an easier way of doing this? I am confused.
Many thanks!

Re: PartDesign Mirrored Question
You can't apply a mirror feature to another mirror feature. For that you need this tool: PartDesign MultiTransform

Re: PartDesign Mirrored Question
Thanks for the quick reply.
I still can't learn from it. I can't make it work. I don't know how to enter the right features and transformations.
Your transformations are not equivalent. The original is modified (feature PocketCenterBearingChamfer missing).
Please see the illustrations.
Could you please explain how to enter the data into the MultiTransform tool? I know it is a lot to ask for and I appreciate your help.
I could not create a MultiTransform based on PocketCenterBearingChamfer which is the best I could find to bypass / replace the first mirror transformation.
Many thanks.
