Thanks for answering, nallath. I ended up doing this to create a cube that touches the buildplate: s = size / 2 dtb = distance_to_buildplate verts = [ # 6 faces with 4 corners each [-s, -dtb, s], [-s, s, s], [ s, s, s], [ s, -dtb, s], # a = x-yz [-s, s, -s], [-s, -dtb, -s], [ s, -dtb, -s], [ s, s, -s], # b = x+yz [ s, -dtb, -s], [-s, -dtb, -s], [-s, -dtb, s], [ s, -dtb, s], # c = xy-z [-s, s, -s], [ s, s, -s], [ s, s, s], [-s, s, s], # d = xy+z [-s, -dtb, s], [-s, -dtb, -s], [-s, s, -s], [-s, s, s], # e = +xyz [ s, -dtb, -s], [ s, -dtb, s], [ s, s, s], [ s, s, -s] # f = -xyz ] where "distance_to_buildplate" is the position in the Y axis of the cube when you click on the model, which is the same thing as the distance from the cube the ground.

Hey guys! I'm working on a plugin (for Cura 3.6+) to enable manual supports, and one of the features I want to add is to show some kind of "preview" of what area the support is going to be taking. Right now, I'm creating a cube and adding it to a X,Y position using this code: active_camera = self._controller.getScene().getActiveCamera() picking_pass = PickingPass(active_camera.getViewportWidth(), active_camera.getViewportHeight()) picking_pass.render() picked_position = picking_pass.getPickedPosition(event.x, event.y) After that, the script creates a cube kinda manually (I'm basing myself on the SupportEraser plugin) with a value entered by the user. Thus, the cube has the same width, height and depth. What I want to do is to make it as big in the Z axis as necessary so that it touches the build plate , and the user can see what it'd look like once it's processed. Is there a way to scale it enough? Thanks!
