How do you make a solid Rhino extrude?

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.

How do you make a surface solid in Rhino?

Drive surface edges in a straight line to create a solid. Create a surface, polysurface, or extrusion object with a circular profile around a curve. Extrude a curve in two directions to a boundary surface. Offset a polyline, and extrude and cap the result to create a solid.

What is loft in rhino?

The Loft command fits a surface through selected profile curves that define the surface shape. Select the curves in the order in which the surface should pass through them. Select open curves near the same ends. For closed curves, adjust the curve seams.

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.

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.

Why can’t I extrude surface in Rhino?

If there is no closed loop, Rhino cannot create a complete trim curve to create the cap surfaces. The object will extrude, but since the Rhino can’t find a complete closed curve to trim the cap surface, it won’t be created, and you will be left with an open extrusion.

Is a closed Polysurface a solid in Rhino?

Mitch says: The official terminology for a closed solid in Rhino is a closed polysurface. A solid has no naked edges. That’s a concise definition.
