I have made myself familiair with FreeCAD/PartDesign/Sketcher.
I know about Bodies, AxleCrosses, Pads, Sketches, DatumPlanes, etc.
I know how to activate a Body. But I do not see any Bodies in the Model Tree of a Bike design which I exported from BikeCAD.
I wanted to create a DatumPlane in the front fork. And turn the front wheel independent from the other parts of the bike. In order to get a better understanding of the steering behaviour of the bike.
Do I have to install another WorkBench, like Assembly ?
Revolving a fork in FreeCAD
I don't have a great response to this question as I have not tried to do this yet. However, I suspect there are likely a number of possible approaches you could take. If you send me your FreeCAD model, I can investigate options at my end.
Working with FreeCAD
On second thoughts, I think I do not have to export a BikeCAD design to FreeCAD. I have found a way to study the steering behaviour of my bikedesign, in a theoretical model. I have build my model in FreeCAD/PartDesign. The model does not look like a bike. But it has a variable Wheelbase, HeadTube (angle), ForkRake, WheelDiameter. The model of the bike is build up out of four sketches. Every sketch has got its own Body.
I have always wanted to know what happens with the stability of my bike when I interfere with the natural rotation of the front fork, while cycling.
For instance, when the center of gravity of the luggage is not in line with the Fork Tube. I am going to use this model to find a better placement for the luggage on the Front Fork....... I will send you my FCStd file by email.......
