||PathCopyPro allows you to select an edge, curve, or polyline path, and then select an group or component to copy along that path. You can copy to the vertices of the path, or specify a distance between copies.
PathCopyPro adds new features to PathCopy:
Toggle path reversal with the TAB key
Toggle object rotation with the SHIFT key
Toggle make copies unique with the CTRL key
There are also three ways to affect the distance between copies:
Type a distance in SketchUp's VCB to set an absolute distance between copies
Enter 0 (zero) to put copies at each vertex
Type the equals sign (=) in front of a number to set the distance to that many equal spaces. For example, typing =7 would create 8 copies at 1/7 the total path length apart
From the Plugins menu, select "PathCopyPro" to start the tool. Select a path, then select a group or component to copy, and PathCopy does the rest. At any time while the tool is still active, you can change the spacing of the copies or use any of the modifier keys as described above.
