[Secondary Development of SolidWorks] sketch drawing-Overview

When you open a new part, the first feature you generate is a sketch. A sketch is the basis of a 3D model. A sketch generates an entity after being stretched, rotated, scanned, or loosed, and then modifies the entity. This is the general modeling process of SolidWorks.

To insert a sketch, you must first determine its placement plane. It can be a preset reference plane or a user-painted reference plane. Or a plane on the object.

The three main information of a sketch is: ry, dimension, and ry.

Sketch drawing process: 1) Select the place Area of the sketch and insert the illustration. 2) insert the sketch and draw the approximate shape. 3) insert size to determine the relationship. 4) Exit the sketch.

1) insert, edit, and delete a sketch. 2) insert the sketch ry (line, arc, and so on ). 3) add dimensions. 4) determine the relationship. 5) Use a sketch tool (rounded corner, chamfer, cropping, image, and so on ).

All Sketch-related APIs are included in the sketch object package. The most important class is sketchmanager.
