Hi @Shalm, hello to the Community!
It simply wants to be an example of the possibilities offered by FC in addition to those already suggested, no control over the rest.
Of course you can use the spredesheet, but in certain situations using a "fictitious" Sketch offers undeniable advantages: it allows me to have many numeric Combo Boxes and immediately appreciate their effects, not having to alternate the view between model view and spredesheet or divide the display in two windows.

Hi,

Thank you everybody. Next piece which gives me trouble will test different methods.

Spreadsheet programming is not that much of my liking :-)

I solved the problem differently as the motor shaft has the flat part and still has left about 2mm of round part again towards the motor plate. I then added another rpiund pocket which brings me the pulley nearer to the motor and chamfering that round hole 1mm deep with no problem and printed pulley did slip like a dream over the shaft ...

I don't think that (ab)using a sketch for this should be recommended, because it obscures things rather than making them clear. Although this needs an addon, I would then recommend using a DynamicData object.

You could do a PartDesign_Revolution, then copy the gear, then add the slot part.

Hi,

Do not understand ?

and BTW I made that gear from Gear workbench and built the other parts upon it but now the refreshing takes very long which I asume it is because of the gear. Is there a different way to build this ? Is PArt workbench in this case faster ?

Thanks

Hi chrisb, hello to the Community!
Certainly it is not an "elegant" thing, let's say a "forcing ...." to obviate the future enhancements of the Spreadsheet.
You do not know how much I appreciated your suggestion (!) (I did not know the Wb :o , indeed I was thinking of such a thing), there is no denying it is a huge Wb, I think to make it enter very early in my "everyday life", dutifully thanks again !! :D

... but keeping all the chamfers outside the sketch could be safer.
