Drawing threads autocad 2012

This is done by setting center points 2 and 3 at one-half pitch and one whole pitch higher in the z-direction, respectively, as shown in the following code:. LSP then uses these new center points in the generation of point lists, as shown in this typical if statement that is part of the get-ptlist function. Last word on screw threads Until now, when I needed to use screw threads in a drawing, I simply made either a surface or a solid of revolution based on a zigzag polyline.

LSP could be a solution. MDT makes threads the easy way Note that Autodesk Mechanical Desktop can create a 3D helical sweep to automatically make a solid model of a thread form. Figure 4 shows Mechanical Desktop's convenient Helix dialog box. You can specify parameters such as the pitch, revolutions, height, orientation, start angle, diameter, and taper angle. Figure 5 shows a solid model thread form based on a triangular cross-section created using Mechanical Desktop.

However, you can easily rectify this by using the appropriate solid modeling Boolean operations to subtract a box from each end of the thread form.
