How To Center Anchor Point On 3D Text - Possible ?

Question

Hello and good morning,I do a lot of fun little spinning 3D text, ( simple rotation on the X axis )Method: - I type out the text, turn it into a 3D layer, add an extrusion on it, and a little bevel. That's it.I cannot see a way to automatically move the anchor point to the exact middle of that textso that it rotates correctly ( centered ) ... currently, I hit the "A" button to bring up anchor, thenspin the 3D text around so I can see the top of it, and then manually move the anchor point so the arrows"look right"  There must be a way to auto-do this.  If there is, I'd love to know the secret ! Thanks so much for your help !

You can add this expression to Anchor Point. It will correct for Base Line shift and paragraph justification. It will throw an error unless the Rendering Engine is set to C4D.

txtBox = thisLayer.sourceRectAtTime();

xLeft = txtBox.left;
yTop = txtBox.top;
yHeight = txtBox.height / 2;
xWidth = txtBox.width / 2;
x = xWidth + xLeft;
y = yHeight + yTop;
z = geometryOption.extrusionDepth * .5;

[x, y, z]

If you want the Z position of the Anchor point to be on the front surface or work with the Classic 3D renderer change the z variable to z = 0;

In theory a sourceRectAtTime() expression expanded with figuring in the extrusion depth might do the trick, but generally anything to do with fonts and that 3D stuff has caveats because what you see on screen does not necessarily represent the abstract exact values you may need for these calculations. Anyway, you can easily find a ton sourceRectAtTime() tutorials that explain its uses, so perhaps give that a whirl.
