Is it possible to revolve a 2d wire frame to a 3d solid. Draw a 2d model (dxf?) and make an 3d model because the use of revolving. HyperMill does this great trick to make a 3d design of a mill or holder.

Hi, At the moment CadLib doesn't have this ability. You'd have to e.g. generate a polyface/polygon mesh manually. Wout

Thanks for your quick reply. Do you know where I could fuind information about revolving? I don't know much about the 3D world in Visual Studio :(

Hi, You can try this approach:  First pick a number of samples with which you will approximate the circle, let's say n.  Suppose you have a number of points with (x, y) coordinates, and you are revolving around the xaxis (or yaxis), then for each point you will approximate a circle with the xaxis as center, so the xcoordinate will remain fixed, and you'll calculate a 2D circle with (y, z) coordinates. You can do this by using (cos(angle) * y, sin(angle) * y), where you'll be sampling a number of angles around the circle.  Now having all the 3D points, you can either create a DxfPolygonMesh, or e.g. a DxfPolyfaceMesh. Let me know if this gets you going! Wout

Is het mogelijk om verder in Nederlands te communiceren?

Hi, You can email me in Dutch, on the forum English is more appropriate so people outside the Netherlands can benefit from this information! Thanks, Wout
