Producing Geometry You Can Trust
Everyone at QC who I came into contact with on our latest projects—from the receptionist answering the phones to the engineers and lab personnel—were extremely friendly and a pleasure to collaborate with. QC was also very helpful in working with our customer to better explain the results and supporting data. Thank you very much!

CAD Modeling Services - With the Application in Mind
At QC, our complex CAD modeling capabilities are born out of extensive industry expertise with precision tooling. Additional industry experience brings a greater level of understanding to our modeling process. Our reverse engineering process begins with an evaluation of the part. We look at the level of accuracy required, your project goals and how the product ultimately will be used. After studying these reverse engineering elements, we determine the level of output you will need. Each of these file types are available to download so you can evaluate the type of output that will work best for your project. 
Native parametric solid models are produced in SolidWorks or Pro-E that are 100% editable. This file contains a fully functional model tree for when you anticipate having to change geometry of individual features of the part. Models are built with design-intent to eliminate unwanted features such as warp, sinks, flash, and ejector pin marks. Parting line and draft are included in the finished model.
Files are output in one of the following formats:
.sldprt .slddrw .sldasm .prt .drw .asm .ckd .ckt .prt .ptn .x_t .x_b 
Non-parametric surfaces, called NURBS surfaces, offer the highest level of accuracy in a solid, ready-to-use file. These are best used with organic shapes. Note: individual features will not be editable.
All surface variations are replicated - including texture if necessary. Accuracy of results are very dependent on the steps taken in the post-processing of the scan. This is the most accurate method of reverse engineering exact geometry for cutting tooling electrodes or another CNC operation.
Files are output in IGES or STEP format.
Hybrid parametric/non-parametric models are used when parametric shapes and complex organic surfaces exist in the same component.
Multiple scanning technologies are used when the project calls for higher levels of precision in select areas of the part. Micro-laser scanning will capture surface finish detail often needed for Class-A tooling.
Files are output in IGES or STEP format.
Polygonal models offer the highest level of surface accuracy, but have limited use. These are non-editable reverse engineering files that are very large in size and can be read directly into 3D printing rapid prototyping technology.
Files are output in STL format. 
Using our technologically advanced CAD modeling services, we'll arrive at a model that accurately reflects the original you provided, one that you can quickly put to use in the next step of your project.
