In AutoCAD, you can cut a 3D solid to produce new 3D bodies in several ways. Consider two ways.
The easiest, use the CUT command (_slice in English version). At the command prompt, type CUT, press Enter, select 3D solid, and then the command prompts you for several options for cutting the solid. You can cut a body by specifying three points (the default) by selecting a flat object, a surface, or one of the coordinate planes (XY, YZ, ZX).
Another way to create another 3D solid completely intersecting the one you want to cut. Next, using the command SUBTRACT (_subtract) cut the desired 3D body by subtracting from it another 3D body.
However, after you use the command REDTEL (_separate), to actually divide the body into several.
AutoCAD is a very versatile CAD program. In confirmation of this, let’s consider a method by which you can translate relatively simple graphics from pdf to dwg format without the use of special programs. The essence of the method is to insert the so-called «pdf Underlay»into the current AutoCAD document. Open the Insert menu, select PDF Underlay. The pdf file selection window appears, select the file and in the next window select the desired page, the insertion point in the document and the scale if necessary.
If the graphics in the PDF vector after inserting into the AutoCAD document to it can be bound by object binding and» outline » the graphics pdf standard means AutoCAD such as polyline, circle, spline, etc.
Several variables are «in charge» of binding to the substrate graph: DWFOSNAP, PDFOSNAP, DGNOSNAP, their values must be equal to «1» for the binding to work.
