Good day.

Question is there something in Moi or another program that I can generate a similar pattern to the yellow gear to use in Moi?

Thank you1

Hi Matadem, in the steps that are listed there, it has step 3 as:

3. Trace the bitmap with pstoedit and export a dxf with potrace

You can probably import that DXF into MoI to get the profile curve, then inside MoI use Construct > Extrude to extrude it into a solid, then Transform > Deform > Twist.

In the description for potrace (https://potrace.sourceforge.net/) it also says it can generate SVG or PDF output as well. These should also work, try those if DXF format doesn't work.

That program will help me!

Question ...Can you in Moi scale down one item smaller than the next?
Let say I have linear array a circle by 10.
but each circle going to the next should be smaller??

tnx!

Yes there is a plug-in here called "ScaleArray" that you can use to apply scaling to the result of any array command:

You just need to include a point object to be arrayed as well, the point is used for the scale origin point.
