Very often there is a need to build a 3D object of a certain cross-section along a complex path, such as piping, wiring, pipes, hoses of sleeves, etc. Such an object can be constructed using the EXTRUDE use the parameter Trajectory. We build the trajectory necessarily using the command POLYLINE geometry can be any.
We construct a section, which we will squeeze out, necessarily perpendicular to the trajectory, in our case, it is a circle.
Select the command to SQUEEZE. In the command prompt, enter «T» (for the Russian version of AutoCAD) ie squeeze sweep. Receive result.
