Rhino 4 NURBS Solid Modeling Tutorial – Model a Webcam Step-by-Step
| Step 51 Activate the FilletEdge command. Click CurrentRadius or type ‘C’ and set the radius to 0.05″. Select the top edges of the crown shape formed in step 50 as the edges to fillet. |
  |
| Step 52 Turn off grid Snap. Turn Planar on. Turn on Osnap, and select only the Quad option. In the Perspective viewport, rotate your model so that the camera is facing the flat circular surface formed in step 50. Activate the InterpCrv command. Set the first point by snapping to the quad on the left side of the flat surface. Disable Osnap after setting the first point. Then from the Top viewport, draw a curve as shown. |
 |
| Step 53 Still working in the Top view, turn Osnap on and select only the End option. Activate the Line command and draw a line as shown, snapping the first point to the end of the curve drawn in step 52. Set the second point so that the line intersects the flat face of the spherical body. |
 |
| Step 54 Still working in the Top view, turn Osnap on and select only the End option. Activate the Polyline command. Snap to the end of the line created in step 54 to set the first point. Turn off Osnap to set the rest of the points, and draw a zig-zag line as shown. To set the last point of the line, turn on grid Snapping and snap to the grid origin. |
 |
| Step 55 Turn on grid Snap. Select the three curves created in steps 54, 53, and 52. Join them, then Activate the Revolve command. In the Front viewport, set the start and end of the revolve axis by snapping to two adjacent grid intersections that are in line with the selected curves. Set the start angle to 0, and the revolution angle to 360. |
 |
| Step 56 Select the ring-shaped surface formed by the revolution of the curve from step 52. Activate the Trim command, and Trim the flat part of the main spherical surface. |
 |
| Step 57 Select everything in the scene by hitting Ctrl+A. Activate the Join command to join all the surfaces into a solid (if you’ve done it right :) |
 |
| Step 58 Activate the Show command to unhide the base and the smaller piece from step 41. Select the base, then activate the Hide command again. Now select the main solid surface from step 57 and the remaining revolved surface. Use the BooleanDifference command with DeleteInput set to No to cut into the spherical body. Activate the Show command to show the base. |
