# Hinge-like 3D 'Rotate along line' function?

## Recommended Posts

Hello,

How do I rotate along line in 3D?

Let's say I have two extruded hexagons that are connceted side by side (see attachment). I'd like to rotate the left one 90 degrees to the right one, like there is a hinge between the two.

2 small details: the connceted side is not and should not be aligned to the X or Y axe & rotating the left hex along the side of the white cube is not the preferred method.

I'm looking for a Vectorworks 3D-function that will do the trick for me...

For now there isn't. You need a working plane perpendicular to your hinge-line.

Close enough, many thanks (as always)!!

Just a little downside: what if it's not a symmetrical shape so I cannot use parallel sides as reference?

Vectorworks offers at least a couple more ways. They depend on Automatic Plane mode operating.

1.      A 2 or 3 step process with Modify>Rotate>Rotate3d command, Move By Points tool (or drag), and Rotate tool.  Select hex A and stand it up by filling the Rotate 3d fields to rotate it 90° about the x or y axis (or x' or y').  Now in a 3d view use the Move By Points tool to snap a corner of hex A to the corresponding corner of hex B.  If hinged edges are not coincident, use the Rotate tool to align hex A: Establish the plane of rotation by hovering on surface of hex B, click on the snapped points to establish center of rotation, click on intended hinge edge of hex A then edge of hex B.

2.  Create a guide object, eg Draw a line perpendicular to the hinge, extrude it to form a plane. Use the Rotate tool to rotate hex A.  Delete the guide object after the rotation.

Use my "Set WorkingPlane By Vector" Plug-in which sets a working plane perpendicular to the vector in its name.
