I started to make some belt pulleys and ran into some annoyances and one possible bug (or misinformation, in case it's not a bug). I use 3.00000000000 version
1. I want to make a T5 pulley. Open the Pulley tool, set the params as needed and add the pulley to the project. So far, so good, Pulley tool is still present and I can go back to it to mod the pulley. Now I want export that pulley as DXF from a project. As soon as I click the DXF button, "Pulley" tool at the bottom of the screen is gone and everything needs to start from scratch.
Related to above - would it be possible to make dxf exports directly from the Tool, not only from gears (and things), that are added to the project?
2. Specific case of a pulley making. I make T5N pulley, 42 tooth, set shaft dia as 54mm. Then I change shaft dia to 6mm and hit enter. Shaft dia is actually entered as 49.5561. Happens every time.
3. Belt length calculator. "42 tooth mating with 42 Tooth". I know "Teeth on Belt" is 82 and want to know center distance. Doesn't calculate, although it says to enter any two factors. Works when I enter only belt length or center distance. Tangent to that, I think it would be nice to fill the input box value automatically to zero, if it is just empty. Currently it asks to enter an integer, even if 3 params are entered and 4th box is empty that needs to be calculated...
