Concept Design with ViaCAD Pro 9 Beta

Sunday, September 1st, 2013

3D printing is shaking up the do it yourself manufacturing communities.  Driven by  the lower cost cost of 3D printers as well as easy to use service bureaus, makers can now go from concept to part with little expense.

One of the features we’ve introduced in ViaCAD Pro 9 is subdivision.  Subdivsion can lower the bar to 3D modeling with simple push/pull modeling methods.  Subdivision also provides a complimentary alternative to ViaCAD’s feature based solid modeling tools that allow the user to pick the best method for a given design.

Check out this video where I use the ViaCAD Pro 9 WIP to create a baby spoon.  You may be in for a surprise at how simple and inexpensive creating plastic or silver plated versions of this spoon!

ViaCAD Pro 9 Mac WIP Update

The development team has announced availability of a Work In Progress build for ViaCAD Pro 9 for Mac.  PC builds will follow shortly.  If you are interested in testing the new release, click the icon to the right.

Some of the new features of v9 include:

• 64 Bit
With V9, all Mac builds will be 64 bit compatible.  This means you can load much larger parts and models. Previously you were limited to around 2.3 GB of model data in virtual memory. I’ve tested a model using over 20 GB with V9 and find this to be one of the more exciting aspects of v9.

•Cocoa
The old Carbon framework used to interface to the Mac OS has been replaced with Cocoa.

•Printing
Printing now supports floating point coordinates for improved accuracy.
Printing now supports previews.
Printing 3D objects in rendered views now support photorendered imaging.

• ACIS R23
Updated core kernel technology from our Dassault Spatial partner.

• Interop R23
Updated core translator technology from our Dassault Spatial partner.

• DWG DXF support for AutoCAD 2013
Support for the updated 2013 DWG/DXF file format.

•Woodworking Joints
We’ve added some woodworking joints. You can now create rabbet, dado (through, stopped, blind), miters, dovetails, and tongue/groove.

• New Quad Mesh Tools
This build includes a new main palette that includes tools for creating quad mesh primitives.

• Subdivision
New tool that smooths a quad mesh.

•3D Linear Duplicate

•3D Polar Array

•Customizable Grids
You now have an option to display the workplane grid as a polar or ISO grid. You can also change the grid orientation by an angle. Use the new Grid Properties dialog box under the Workplane menu to explore the different options.

*OpenGL

We draw our 3D data to the screen using OpenGL. In the past, we composited objects that did not have a 3D opengl equivalent using 2D. The result was a small frame delay for compositing the 2D frame into the 3D frame. With V9, those draw elements that do not have a 3D opengl equivalent are drawn into an overlay window on top of OpenGL. End result, frame rates have the potential to be faster in v9, more testing and benchmarking needed.

•General Performance Improvements
Large file performance much improved as a result of improvements to ACIS R24 kernel and Interop, 64 bit, and OpenGL performance.
