It is mostly just a nuisance, any help would be appreciated. Trying new ways of doing stuff and I could only use the curves on one side so they did not even work for what I wanted. Go figure.

It is mostly just a nuisance, any help would be appreciated. Trying new ways of doing stuff and I could only use the curves on one side so they did not even work for what I wanted. Go figure.

Try to select any brush that using curves like “ZremesherGuides” and left click on the model away from actual curve lines
PS. I’m not sure to have understood you. But if you have meant both sides. Then make:
A.) Set your created polygrouparea also on the other side with the Mirrow and Weld function:
Tool > Modifiy Topology > Mirror And Weld. And you receive the same created polygroup area at the other mirror side of your model.
B.) Or: created by hand your curves also on the other side, like in your image is to see. Hmm…
The ZRemesherGuide brush solution from Piosio worked for me!!! Thanks man
