SolidWorks is available for Windows operative system in several versions.

From the Sketch section on top you find all the tools to 2D-draw.

You can select points, lines and curves, setting their options from the Property Manager on the left.

You can select points, sides and curves to drop useful annotations on any distance, length or radius but also correct them on-the-go by typing in and applying with the Enter key.

The way to draw 3D Sketches is identical to 2D ones, enabling any drawing tool and selecting the right plane.

On the Features tab you will find several tools to build 3D objects from 2D entities that can be either 2D or 3D Sketches, depending on the tool.

You can select any face or contour and use the arrows to adjust the extrusion or move these.
