Hi Nick,

I agree that you can get very good results from the latest releases of software that have borrowed heavily from the platforms of CAD packages such as SW and Inventor. They will most certainly do much of what the average user will expect of them, particularly when most of the output required is comprised of more basic geometric shapes -- cylinders, cones, blocks, etc. which, when grafted together, form the object to be modeled. For instance, the arm of a Welin davit is nothing more than a construct of several dozen basic geometric shapes. Such software could remove a lot of the drudgery involved in making parts were a lot of "repeats" are required. (Unfortunately, at least for me, it also removes a lot of the artisanship of crafting scratchbuilt models or parts, which is what attrached me to model-making in the first place!)

The place where trouble can be encountered is in producing accurate and error-free solid models of something such as a propeller. While free-form shapes such as a propeller blade can be adequately modeled in many software platforms and will work fine for creating representations on line drawing or for creating a surface mesh for use in CGI work, the results obtained will often produce failures in the form of tiny gaps and mismatched surface edges that will fail to produce a "solid" during conversion to a STEP file or and STL. And, to be fair, even very high-end CAD software is prone to these difficulties.

Regards,
