# Rotating Objects in 3D

## Question

I've been struggling with Vectorworks 3D rotate for a long time, mainly when having two rotate non-cube objects along multiple axis. Here's how I'm doing it. There's gotta be a better way.

I have this multiple extrude object, essentially a rectangular pyramid:

From the side it looks like this:

From the top:

If I want to rotate in 3D in ONE direction it's easy. Say I need to tilt it down 45°

I go to the side view, here's what I do:

Great:

Here's how it looks from the top:

Now I need to rotate it 45° on the Z axis (panning it), great:

Now I want to fine tune that rotation. If it was still aligned like the first view, I would do this:

But now the side view looks like this:

I would think that solve here is to use the working plane somehow. I need to align my view to the side of the pyramid so I can rotate it along the Z axis.

So I've made the working plane the "bottom" of the pyramid and then extruded a line on the side of it:

Then I've made that extruded line the working plane:

Now I can fine tune the objects' 3D rotation on the Z axis.

Is there a better way to do this?

Adding some 3D Loci to strategic points within the frostum symbol could help. Then snap the rotation tool to these loci. You might have to enable 3D loci visibility in your prefs. Its a theory but maybe worth a shot

I made a frostum out of 3d polys and added 3d loci to the top center and front and the tip. I can snap my rotation tool even in isometric view and rotate away

Only you would know this is a frostum !

If understanding properly:

Then group those bad boys. Using this method, it sometimes works.

Right now in left iso, if I use the rotate tool, I get a rotation along this axis:

If I go to the side view, I can do it by the side, so now I have rotated it a long a few axis:

Cool. Now how do I tilt it down even more? This is the plane it's giving me:

I can use those 3D loci to create a temporary working plane and then use that for rotation. Ah right obvious!

I've added a fourth 3D loci so I can use the working plane method for both panning and tilting:

After some more tinkering, technically, you don't even need 3D loci (though if you add shift your frostrum it might be useful). You can select the mid-points of each plane and the tip to select your working plane. Works like a charm. Can't believe it took me this long to figure this out... Not super intuitive!

If only you could select a 3D anchor point for an object and control all of this stuff in the OIP 😞 like any other program 🤯

Or 3D handles:
