Dear Ashlar-Vellum: Most laser and waterjet cutting vendors that I’ve contacted prefer solid models in a SolidWorks format over any other format. I would prefer, however, to use my MAC and either Argon, Xenon, or Cobalt. What should I do to send files to laser and waterjet cutting facilities who ask for a 3D solid in a SolidWorks format?

The spline tools in all Ashlar-Vellum CAD and 3D modeling products create NURBS (Non-Uniform Rational B-Splines) which are a superset of Bezier curves. These splines are curves created by a complex mathematical formula.Read the rest.
Ashlar-Vellum’s technical department is often asked, “How do I import and edit a PDF into Cobalt (or Xenon or Argon)?” It’s a good question with a very complex answer.Read the rest.
We’re often asked what’s the difference between our 3D modeling products Xenon and Cobalt. When we say that Xenon has associative parametric modeling but Cobalt also includes geometric and equation-driven parametric constraints, most people’s eyes glaze over and they do one of two things, usually for the wrong reasons.Read the rest.
Occasionally our tech support line gets a desperate call saying, “When I open my CAD or 3D modeling drawing, it’s become a tiny speck!”Read the rest.
While Ashlar-Vellum 3D modeling products do not currently have specific sheet metal commands, thousands of sheet metal designs are created each year in our software.Read the rest.
Ashlar-Vellum CAD and 3D Modeling products export data to any number of Finite Element Analysis (FEA) programs. The issue is getting the data to the target program. FEA is a serious science best left to professionals using something more than the “light” FEA features built into some competitive CAD packages.Read the rest.
Rendering within 3D modeling software is all about simulating the real world as much as possible. Lighting and the scene are the most import things to start with when setting up a rendering. Once the lighting and the environment are correctly set up, everything else falls into place.Read the rest.
If you’re having difficulty finding something in a file imported from AutoCAD and think Graphite v8 CAD software didn’t import the entire thing, try using View>Sheets. A new feature in Graphite v8 is the support for what AutoCAD calls layouts and Ashlar-Vellum refers to as sheets.Read the rest.
There’s nothing more frustrating than getting an email back from tech support saying in effect, “We have tested the issue on three machines in our office and cannot reproduce the problem.”Read the rest.
Graphite users often ask how they can trace over an image in our precision CAD software. While this is a convenient technique for general shape extraction, it does not necessarily provide a precision drawing. Both parallax caused by the camera lens and perspective of the photograph greatly effect the accuracy of the drawing.Read the rest.
You’re hard at work putting the finishing touches on a 3D model when suddenly it won’t shell or the edges can’t blend. On the screen, as if out of the black lagoon of 3D hell, looms the dreaded ACIS Error. Horrors! How was this monster invoked and how can you avoid becoming the object of his evil eye ever again?Read the rest.
