Make your own lathed 3d shapes!

Just move the black dots in "edit mode"
When you want to see it in 3d, change it to "View Mode"

Try making Cups, Classes, Bowls, CD's, Tops, Lamp Shades, Tires... Anything symmetrical!

Feel free to save and share your work! Download and edit in scratch.
I'll add it to the Lathed 3d shapes gallery.

HOW IT WORKS:
When you enter "edit mode" every dot moves to it's x, y location and becomes visible, and it's drag-able so you can move it around.

When you enter "view mode" every dot becomes invisible, and copies it's sprite location to it's x, y.
Now it sets the DrawRotY to 0 and increments it based on the "DrawSteps" setting.
for each of those increments, every dot's x,y location is rotated twice: First to the "DrawRotY", then to the "CamRotX", then the point is moved back from the camera "CamZ". After all the points are moved to where they go for that step, the "draw" sprite, with the pen down moves to all the points 01 through 16. Also all those points have the pen down so they draw the horizontal lines as they're rotating along the "DrawRotY".

Let me know if you have more questions.


UPDATED:
Now with color picker.
(link to project)
Drawing now resets when sliders change.

KNOWN ISSUES:
It makes stray lines sometimes when changing values or switching to view mode.

Please "love it" if you do!
