====== CAD Modeling ======

===== About =====
I can help you develop CAD models based on anything that you would like to make. I specialize in making models that take into account the tooling that will be made to manufacture them. Not only can I help you create parts that meet your mechanical and aesthetic requirements, I can optimize the geometry to be cost effective to actually make.

I have the most experience with Fusion 360, but am also familiar Solidworks, and OpenSCAD. I can provide solid or surface models in a wide variety of formats depending on your needs. I can also provide models that are parametric.

Examples of my CAD work can be found on [[https://grabcad.com/robert.kuyper-1|GrabCAD]].

===== Terminology =====

  * CAD: Computer Aided Modeling is the use of computers to create, modify, or analyze a part.
  * Solid Model: a digital representation of an object that understands that the volume of a part is filled. These types of models are often used for engineering analysis like Finite Element Analysis.
  * Surface Model: a digital representation of an object made up of surfaces that understand the inside and outside of a face but not that the part is filled.
  * Parametric Models: a model that has a table of values that can be changed to dynamically change the part. If you want to offer two sizes of a part or a varying number of holes, this can often be generated with a parametric model.


As long as the surface model has no holes or overlapping geometry, it will typically be interchangeable with a solid model. Solid models enure that there are no holes or overlapping geometry in a generated mesh.
