Hi,
I want to cut two equal sized parts from the left and right side of a sphere.
Is it possible to cut both parts in one step? So i don’t need to worry that both parts are of equal size?
If the mesh is symmetrical it’s probably easiest just to do one side in whatever manner you wish, and then Tool > Geometry > Modify Toplogy > Mirror and Weld the change to the other side (only works in one direction, so sometimes its necessary to flip a mesh to the other side first with Tool> Deformation> Mirror).
Live Boolean can always be used to set up complicated cuts with other subtools that can be placed symmetrically.
But still the middle edge loop is not melted correct. Do I need to add an edge loop?
It looks like your mesh was slightly off-center. That’s typically what causes seam issues like that.
Try moving your mesh towards the mirror plane slightly before performing mirror and weld, so that the problem geometry is cut off by the M&W operation. If it’s just a small problem area, pull the individual points across the mirror plane with the move tool, so that they are cut off by the M&W operation.
It may help you to visualize the mirror plane by switching on the floor grid with the proper axis active. Make sure the elevation slider in the Draw menu is set to zero.
Thanks @Spyndel that sounds quite tricky for such a simple correction. That is why I am thinking of sculpting without such geometric operations. Indeed I saw a lot of professional zbrush sculptors starting with an already high polygon mesh to sculpt. Like working with real clay. In the zbrush lesson there is a beginner tutorial explaining how to sculpt a head by starting with really low poly and then step by step going imto detail. But as I know of decimation master and other tools do I really need to think of having a low poly mesh at the beginning? How would you start sculpting human anatomy?
