Can you edit an extrusion in rhino?

How do you edit a closed Polysurface in rhino?

You can, in Rhino, select faces by Ctrl-Shift click (Sub-object select) and then use Move, or Gumball (Set Gumball to orient by object) to move the faces. You can also use SolidPtOn. Keep in mind that things can get squirrely pretty quickly if the faces get twisted up.

How do I edit surface in Rhino?

Change control point structure

Insert a kink at the start/end of a curve or surface. Remove the kink from the start/end of a curve or surface. Reconstruct curves, surfaces, and extrusion objects to a specified degree and control point number. Restore surface edges to their surface.

How do you change points in Polysurface Rhino?

To control-point edit a polysurface, Explode the object into separate surfaces first or use the ExtractSrf command to separate the surfaces you want to edit. While control points are on, they can be selected and deleted. This changes the shape of the curve or surface.

How do I make my extrusion longer in rhino?

If the extrusion is vertical use Command-Drag or Move > Vertical to constrain the point. Gumball can also help. My favourite is to command+click the extruded edge(s) , or surface if extruded solid, and pull with GumBall. You can do this but it will no longer be an extrusion object, if that matters.

How do you convert mesh to Polysurface Rhino?

Converting a Mesh to a Solid in Rhino

  2. Apply Mesh > Mesh Repair > Unify Normals to all component meshes.
  3. Join all component meshes with Mesh > Mesh Boolean > Union.
  4. Enter “MeshtoNURB” at the command line to convert mesh to solid.

Can you undo a boolean union in rhino?

Is there no way to make it separate again? There isn’t a one-button function to do that, no. You can extract surfaces and untrim those, then join back into the original objects.

How do you make an extrusion solid in Rhino?

To make a solid extrusion from a closed planar curve, make sure Solid=Yes at the command line in ExtrudeCrv . If the curve used to create the extrusion is closed but not planar, then EdgeSrf (prefered if it works) or Patch can be used to close the ends. Then Join with the extrusion surfaces to form a solid.

Can you extrude mesh in Rhino?

The MeshExtruder type exposes the following members. Construct object to extrude given mesh faces, edges and ngons. Whether or not to keep original faces.

How do you make Polysurface in rhino?

Draw a pyramid. Extrude a curve in two directions to a boundary surface. Offset a curve and create a ruled surface between the curves. Offset a polyline, and extrude and cap the result to create a solid.
