If you are looking for an affordable 3D mechanical design software with a rich set of standard parts included, then BricsCAD is your right choice.
To access the library of standard parts, open the Mechanical Browser panel. Then click on the “Library” tab. You can choose between 13 different standards, including ANSI, DIN, and ISO. All the parts are grouped into categories.
Expand a category to see its content. To insert the selected standard part into your model, just drag it from the library and drop it in the drawing area. You can use dynamic dimensions and snapping to position the part precisely. For many parts you can also specify the length.
