I am modelling architectural ornament and I created one side
of it and tried to mirror the other side but got a failure message
saying that it would "result in zero thickness geometry"
I created this with a swept loft.
Try mirroring bodies.
As Tony said you should use mirror bodies when mirroring as you are there.
I tried mirroring bodies but I got a message saying "failed to merge the newly
generated body with the work piece."
Can you post your part
Try checking Geometry Pattern to see if it helps. I also have problems mirroring sometimes but after playing around with the options I usually get it to work.
Double check with a fine comb that your reference planes and sketches are all on the up and up. If no error ifs found there, try extending the surface a little bit at the plane the feature is to be mirrored about. Then trim the surface using this mirror plane, attempt the mirror feature.
Rarely something I've noticed or experienced is similar to this scenario. A normal mirror feature doesn't work, mirror body merge result doesn't work, though mirror body do not merge result + combine feature later on does work.
Here's the model. When I did the loft it seemed like the loft wasn't following
the guide curve closest to the mirror plane exactly. It looked a little off.
I cleaned up some of the faces into and was able to mirror.
Thanks Martin, How did you fix it?
Thanks to everybody else too. I learned a little more about this command.
I had to delete and patch a few faces as they weren't planar with the cut extrude.
Anytime a feature or body crosses your mirror plane you will get this problem, I usually go to "Check sketch for feature" to avoid This.
Martin, I couldn't open the file you sent but I tweaked the extrusion and was able to get mirror to work.
Tony, where is the "check sketch for feature command" Is this the check command in the toolbox?
I have another question for the same model. In this model I created a projected curve. Is there
a way to mirror projected curves?
While in the sketch go to tools-Sketch tools-Check Sketch for Feature.
As far as the second question, you can't mirror the sketch itself, but if you create a swept feature, you can mirror it.
