Frequently asked questions
What is the difference between 2D and 3D CAD software?
2D CAD software like LibreCAD and CorelCAD creates flat technical drawings and blueprints. 3D CAD software like Onshape and OpenSCAD builds three-dimensional models. Some tools like NanoCAD support both 2D and 3D work.
Which CAD software is best for beginners?
LibreCAD and Inkscape are excellent free starting points for learning CAD basics. Onshape offers an intuitive cloud interface with no installation needed. Choose based on whether you need 2D drawing (LibreCAD) or 3D modeling (Onshape).
Is DWG file compatibility important?
Yes, if you work with colleagues, clients, or firms using AutoCAD. NanoCAD, Onshape, CorelCAD, and Vectorworks all support DWG files, ensuring seamless collaboration with industry-standard formats.
Can I use CAD software without paying for a subscription?
