3D UG-NX (IDEAS) 3D SolidWorks

3D Parametric CAD has 3 Basic Functions - To Create,Parts, Assemblies, and Drawings / Documentation

Note: Parametric means that If the part changes, the assembly and drawing will reflect the changes also

Sheet Metal Modeling Weldment Modeling

Part Modeling is created by Sketches - it is assigned a Material, Specifications and you can Linked Values to a spread sheet for easy Future Modifications

Weldments are created with 3D Sketches that are assigned an Extrude Member that generate Cut List

This presenation only shows a small part of the many capabilities of CAD technology. All the models and drawing were prepared by myself with various CAD programs.

If you are someone who is trying to understand CAD, I hope this was a help.

If you are someone who need someone to help them create new design and documentation, I hope you will use the number below and give me a call.

Thank You for Your Time.
