I am trying to get slice brush to act like a true planar wire cut relative to view. it seems to be doing some kind of averaging. in my images i am trying to show where the slice is not going through straight. any way to straighten out the slice brush?
When the slice brush is used, it only really cuts the slices the exterior of the mesh. It’s great for making straight cuts through a mesh, but it doesn’t “cut through” and flatten the interior when remeshed if sliced along a complex curve. I like to think of it as slicing through a hard candy coating with a liquid center that oozes out.
In those cases where you need that kind of cut accuracy, make the cut with a boolean object instead of slice curve.
One way is to insert and shape a negative cutting object that encloses the volume to be cut, duplicate the subtool, and perform a subtraction operation on one, and an intersection operation on the other.
Another way is to simply craft a long, thin (but not flat) negative shape along the desired cut path, and subtract that shape.
wow, that is really disappointing… looks like a case of “so close, but yet, so far.” that puts a bullet in this tool for me. would be amazing if it worked. way better than having to build boolean object.
It would only “put a bullet” though the tool, if there were some easier or more effective way to quickly cut up meshes for dynameshing. As long as those are simple straight cuts, or cuts not needing to result in mechanically precise form, I don’t believe that there is. And it is still effective as a tool for dividing polygroups.
There are simply limitations to it when needing to make precise, complex shapes. More ambitious forms currently require more complex technique. Yes, we can hope to see the functionality improved. But those limitations don’t make it not work for what it is good at doing.
Yes, it does slice up polygroups well. I am using ZB for industrial design/toy work. ZB is getting SO close to being a viable industrial design tool.
I primarily use Rhino and T-Splines. I have used Freeform and SolidWorks. all of these tools have wire cutting tools that work well and cut through volumes. That is why I dont understand why the slice brush drops the ball on the interiors. I dont understand why the gooey centers is considered acceptable. There is so much that is great about that tool being in ZB the way it exists in other software.
