Sjack Abeling Gravity Wheel and the Worlds first Weight Power Plant

@ Omnibus,

I have never seen in WM2D more than a rough guide. It is of limited usefulness.

Having said this, it is a quick way to mock something up and study its behaviour under differing conditions. Something that would take weeks with a real model can be done in a matter of hours. So what if it is not precise? It will give a good idea what to expect in a prototype.

When WM2D goes wrong it goes so wrong that it becomes obvious something is amiss.

The moment it starts dropping constraints for instance you know it goes haywire. The programme is a long way away from being a true simulation of real processes other than the simplest systems.

@ruggero,

I finally found a way to save a drawing in SolidWorks as a dxf file. However, to have a functional drawing imported into wm2d turns out to be a very complicated task. If you draw the grooves in the Draw section of SolidWorks, the way they are drawn in the Parts section of SolidWorks (an image of which I already posted), these grooves appear as separate solid entities in wm2d and not as holes in the wheel. They have to be subtracted somehow from the wheel while still in the Draw section of SolidWorks (as they are extruded in the Parts section of SolidWorks). Don’t know how to do that yet, if it’s at all possible. Another approach would be to draw certain number of segments of proper form which when put together would make up the wheel w/ the grooves, if that makes sense to you. This is a hell of a job.

If an imported polygon contains errors try converting that polygon to lines (Object -> convert to lines). Then make corrections to the object in line format and when done reconvert all the lines to a polygon by using a reverse conversion (Select all lines and then Convert object -> convert to polygon)

That´s how I basically make all grooves in wm2d

Can't do it. Observe, for instance, a simple example -- I want to have a wheel with one small circular hole. No polygons. In the Part section of SolidWorks it's easy to do -- you just Extrude the hole through the entire body. That can't be done in the Draw section of SolidWorks. The two circles, the large, that is the wheel, and the small, that is the supposed hole appear as two separate solid entities in wm2d. The only way to do it is to have the wheel be composed of two halfs which when put together form a wheel with a hole.
