# A simple idea for Version 11

## Question

For some time Vectorworks has had the extrude rectangle tool. Why haven?t NNA implemented a extrude circle tool on the same tool set? This would be great for 3D piping, 3D handrails and other such things. I know someone is going to tell me you can now use nurbs and/or use the extrude command to do the same thing but these methods can be tedious if one simply wants to draw a freehand run of piping or rail. I suppose the question then is how does one turn corners and intersect a run of piping with another? The answer may be nurbs but a more elegant solution would be to use a sophisticated fillet tool for turning corners. As for t and y intersections I appreciate this would be a tricky bit of code, but probably worth it, as 3D piping type elements are used so often in construction and architecture.

It would be fairly straightforward to reuse most of the cone tool to work as a cylinder tool, but other stuff has seemed more important. But it's on my personal suggested future projects list.

I think what is really needed for that is a 3-D pipe plug-in. The plug-in would have a 3-D path, created from a (degree 1) nurbs curve, and a radius and diameter value. The plug-in would generate a pipe of the given diameter corresponding with the provided path, putting in curved pieces at the corners.

This is a lot like an extrude along path of a circle, except for the automated corner generation. You could combine pipes by doing an Add Solids operation on them. I added this idea to the wish list not that long ago.

I made a Plugin for such purposes, unfortunately it has one small bug. If the bug is eliminated maybe i will consider to make the tool availlable to others.
