Problem rotating a component accurately

rickgraham

Hi all,

See attachment. I want to rotate the blue face at the point specified to the other end specified. I tried with using the copy/rotate, but the rotation only allows from the center of the component (not the ends). I tried to use the rotate but the compass won't align vertically.

Is there a method that I'm missing?

Thanks,

Rick

Hi Rick,

Could you attach the files directly (I am not sure what you want to attach as the Mac makes a whole lot of extreme subfolders and exotic file types for a single image). What is a "voila" file type, anyway?

Oops! The file I wanted to attach should have been a .png file. Voila is the screen capture program I use.

Here is the .skp file.

Thanks!

Well, in such a twisted case, the easiest thing is to temporarily move the axes (see attached where I put the origin into the pivot point, the red axis along the intersection of your shapes and the green to where the red originally was - so the red/green plane is now the same as it was but you could also align it with the face of your component).

From here on, you can force SU to rotate it along the (current) green axis by

left clicking into the origin/pivot point
while still holding the left mouse button, dragging it along the green axis
when it turns into green, releasing the mouse button
clicking into the intersection of your leading triangle and the component plane
starting the rotation
finishing it by clicking on the upper endpoint of the triangle.
If you want the axes aligned to the component face instead, right click on an axis and > Place. In this case
with your first click, you establish the origin
with the second, the red axis (best to place it where it is now)
with the green axis, click on any of the far endpoints of your component.

heres a quick explanation of how you can do it without fiddling the axis.

Ahhh Axis - way cool! Didn't explore that far. Thanks!
