How do you Compare CAD Models?

The need to compare CAD models Imagine you are an estimator who works for a mold development company; a prospective customer sends you a CAD file and asks for a quote to have a mold made. You pull up the model on your CAD or viewing system, make a few measurements, and take your best guess at what it might cost to make a mold for this part. You send the quote to the prospect, and a few weeks later, they send you a revised part and ask for a new quote; they also communicate that the only change is the size of one hole. Your inclination is to do a quick visual check to verify there are no other changes, and quote a similar price to the prospect, since this is...
CAD Model Validation

CAD Model Validation

A Recent CAD Forum Discussion Reading various CAD forums can be illuminating. Here’s a paraphrase of a discussion on a recent CAD forum where a CAD engineer is looking for a way to test if the original CAD model has been changed in any way when translating from CATIA to STEP to SOLIDWORKS. So the question is, if CNC machining or other operations are going to be performed on models that were translated from the original, how do we know that those models are accurate? Let’s look at the question and some of the answers. Question We do aerospace design, and are sending a lot of models to subcontractors for CNC machining. During the CATIA to STEP...
MagicCheck Micrometer Tool

MagicCheck Micrometer Tool

The MagicCheck Micrometer is a simple yet powerful tool that allows you to easily, instantly and precisely measure discrepancies between two parts. When the Micrometer tool is used with MagicCheck, it does more than simply calculate part thickness; because the context of MagicCheck is part-to-part comparison, the tool calculates part thickness for both the Source and Target parts, as well as the distance between those parts. The Source part is always assumed to be the first part selected via the Open Parts dialog box, and the Target part is the second part; the order of Source and Target parts can be modified in the Open Parts dialog. Micrometer Dialog Box...
