Re: Need Help Completing Drawings ASAP Please!!

I reused mem2704's model. As it broke on recompute I used a cheating trick: I left everything as is, made a simple copy of the mat, hid the original mat, and used the transfor tool to turn the simple copy and shift it in place. Done :mrgreen:

At home, in France some ecologists believe that wind turbines are not beautiful in the landscape, so they propose to bury them, :lol: :lol:
if you prefer that way , I'm OK :lol:

Work in progress.
Expressions + part/body concept works really fine.
Number of fanblades, angle, intersection change by values in spreadsheet.

Done in Part Workbench with all dimensions in a spreadsheet.
I've collected a few dimensions at the top for change tests, all yellow cells have an alias and are used in sketches and placements. Green is for marking cells that are used by expressions in the spreadsheet. Values in white cells are for remembering the standard dimensions, changes here should not affect the model.

I was going to model it using the Spreadsheet approach like Boneshaker used, but now I don't have to do that :lol:

According to my dictionary it is a children's toy which spins around a vertical axis.

The cat would have made the puzzle obvious. :D

I was curious about your way of modelling this.


Maybe we make a monthly FreeCAD challenge in the showcase forum to build a library of more complex examples.
