...you transfer this angle to each of the pinions But not using manual cut n' paste please. That leads to the mistake outlined below. By putting a named reference angle constraint on the Sketch and using that in an Expression for the pitch angle, the exact angle is reproduced. The angle in your scr...

When the fasteners appear in the model tree, is there any common property/name that could be used in a macro to identify them as a fastener 'object', and change their colour accordingly? Pseudocode: For object in tree: If object == fastener object: change colour to pink repeat until tree is traverse...

If you are doing this in FreeCAD, your drawing has too much information on it. You only need four of five angles and four of the five sides. See attached. The centre point (vertex) is fixed at a height of 5mm as requested. You can drag it around and the unfolded (called the 'developed') shape should...

This is not a FreeCAD question. It is a 'principles of bevel gearing' question. Only bevel gears with a 1:1 ratio have (what FreeCAD calls) a pitch angle of 45 degrees when meshed at right angles. You need to alter the pitch angle of each gear according to the ratio of the tooth counts (100:20). You...

...often times they are used to keep objects tight together and spaced out or apply pressure. Those are more an engineered washer. A common type is called a Belleville washer. They have defined properties as you say (https://www.sciencedirect.com/topics/engineering/belleville-spring). I get the imp...

Where can I find spring washers on fasteners library? You cannot. They are on the 'to do' list. Search 'freecad spring washer' in a nearby Google to find out further information if required. Post a link to a publically-available dimensional standard for the items. Knowing the dimensions, it is poss...

The only way I know of to "keep" a configuration, is to make a simple copy. Then change the table, make a copy of that, change the table, make a copy. Could you make the copy of the model/geometry as you suggest and then use the Label2 of each copy to pick the dd parameters required. If y...

....of course it's faster If it is really that simple, I wonder if it is worth a feature request for Draft, to add a 3-point circle as a drop down button to the standard circle one. It sounds like the code for three point arc could be re-used with just one additional step (setting Last Angle = Firs...

As an alternative to drawing a circle after the arc, would it be faster to select the arc, select its properties and make its Last Angle equal to zero?

...I guess revolution and groove won't work. That is being a little unfair on those trying to help and also a little under-studied in FreeCAD's abilities. Think of it this way: a rotation is a special case of an additive pipe (sweep), where the path along which the profile is swept happens to be a ...
