Spin problem

Why wont the spin work correctly.
i am looking for the shape to be radial around the cursor?

nks
thanks
using 2.69tempkeys
this is what i am aiming for with 35 white keys not 36
thanks

I am not sure what you mean by spin. I assume you are trying to use a modifier (mirror or screw, with object offset [an empty at the center and rotated]). I played with those, and noticed that your object scale is not “1” and it has a rotation. Perhaps applying the scale and rotation would help (CTRL-A, and chose rotation and scale). Maybe even apply location, too, to have the object pivot at the center?

If that does not work, and considering there are not that many objects (keys) involved, you might just try modeling them.

I tested this method: (with keyboard shortcuts)

The White Keys:

  • Note that I would save the bevels for last, or even just use the bevel modifier instead.
  • Center the cursor (Shift-C), and set the pivot to be the cursor (Period key, 6).
  • Select the one key on the y-axis, make a linked duplicate (ALT-D), and rotate it around the z-axis by 360/35 (10.285). [Alt-D, R, Z, 10.285].
  • Go into edit mode, change the pivot to median (Period key, 8), and scale the “front” and “back” faces on the x-axis (S, X, drag mouse) so they just touch but do not overlap
  • Assuming you do not want linked duplicates, delete the linked duplicate you made previously.
  • Set the pivot back to the cursor (Period key, 6), select the original key and duplicate it with Shift-D, R, Z, 10.285, and press the Enter key. Then press Shift-R to repeat this process around the circle (i.e., hold the Shift key and tap the R key 33 times).

The Black Keys

  • Select all the white keys and rotate them around the z-axis by 10.285 / 2. This way you can model the black keys on the y-axis as you did the white keys.
  • Model the black keys as above, creating 35 of them, and delete the ones you do not want.

Note for the rotations (360/35), I used the computer’s calculator, copied the result , and pasted it in (10.285714285714285714285714285714, for reference). Or divided by 2 for rotating all the white keys before adding the black keys. Blender does not let you do math in transforms by default, though there is a setting to allow, for instance, “R, Z, 360/35” if I recall.

Lastly, I also noticed that your top and bottom faces were tilted with respect to the X-Y plane. I would start with a fresh Cube to model this.

here is the spin tool.
thanks for your explanation
never had to do anything that complicated before when i did a spin.
suspect there is something i forgot
thanks

I think you need to toggle Dupli.

Thank you very much
dupli it was!

Sorry, I did not realize it only showed up in edit mode.
