CAD Data

CAD Data

This overview of CAD Data focuses on Mechanical CAD (MCAD) applications and industries which have to do with the design and manufacture of products. CAD data can be 2D or 3D, composed of wireframes, surfaces or solids, and represented by polygons or voxels. CAD data can contain underlying spline or analytical geometry, gaps between faces, and formats can be ASCII or binary. It can contain PMI and UDA data, and can output that data to sharable formats such as 3D PDF and WebGL for anyone to view in a 3D viewer. It can be extracted to XML and other formats for analysis to help designers and manufacturers improve products and processes.   2D CAD Data This CAD...
Four Threats to Manufacturing On-Time and On-Budget

Four Threats to Manufacturing On-Time and On-Budget

Avoid Million-Dollar Manufacturing Disasters In engineering, something as simple as declaring the wrong unit of measure can create a disaster costing millions of dollars. John Pike, space policy director at the Federation of American Scientists, stated, “It is very difficult for me to imagine how such a fundamental, basic discrepancy could have remained in the system for so long,” regarding the English to Metric units mistake at NASA [1]. Watch the video overview. Article continues below. Four Threats to On-Time and On-Budget Engineering disasters can often be traced back to design errors that creep into downstream manufacturing processes through...
Top Blogs of 2016 & 2017

Top Blogs of 2016 & 2017

We’ve covered a lot of ground in the past two years. Here are the top twelve TransMagic articles from 2016/2017. Actually, it’s hard to measure what the top blogs were in any given year; do you count the number of views? In that case, older articles have a definite edge. In this case we looked at the posts getting the most views during the last 30 days. Here they are: #1. SOLIDWORKS Performance! Optimizing SOLIDWORKS Performance: SOLIDWORKS is still the clear leader in terms of existing MCAD seats, and is always a popular subject. This article goes over several hardware and software suggestions for significantly improving SOLIDWORKS performance....
Materials and Mass Properties

Materials and Mass Properties

This article will demonstrate how materials are applied to models in TransMagic R12, and how parts and assemblies can then be interrogated for Mass Properties. Mass properties are particularly useful if you are generating quotes or estimates, and need to know the weight or volume of materials for the part or complete assembly. Another common use for mass properties is to get the volume calculation for estimating 3D printing print times and material costs. The Mass Properties dialog box also provides moments of inertia and allows you to create three planes that intersect at the centroid. Applying Materials Parts should already have a default material assigned;...
CAD Data Extraction

CAD Data Extraction

As mentioned in last week’s article, CAD files are rich sources of information which can be used to better understand and optimize the entire design and manufacturing process (see The Digital Thread article). ‘Informating’ is a term coined by researcher Shoshona Zuboff, who used it to describe, among other things, “computer-based, numerically controlled machine tools or microprocessor-based sensing devices (which) not only apply programmed instructions to equipment but also convert the current state of equipment, product, or process into data”. This newly available data can then be analyzed to gather new insights into our, in this case,...
CAD Repair in Seconds Flat

CAD Repair in Seconds Flat

All core TransMagic products come with the Auto Repair Wizard and Lite Repair, giving you CAD repair in seconds flat. By default, every model that is opened is evaluated by the Auto Repair Wizard (ARW) to see if it is a watertight solid, and if there are any underlying issues. In the before-and-after image at right, the ‘before’ image has different default colors for each face or surface; this is an indication that you are dealing with an group of surfaces rather than a watertight solid model. In the ‘after’ image, the color of the model is uniform, indicating that the model is a cohesive solid. Based on what the ARW finds, it will...
