Mesh to Solid in Geomagic Design, New Update

CADDIT announces the availability of a new update for Geomagic Design with enhanced mesh to solid functionality and other enhancements. Geomagic Design is a complete but affordable 2D/3D CAD system for mechanical design similar to SolidWorks and Inventor, and  available through the CADDIT.net website in Australia since 2009. Version 16 recently added milestone mesh import and conversion functionality to the already large set of design tools including parametric and direct solid modelling, assembly and sheet metal design, BOM and 2D drafting along with a large collection of third party applications for motion simulation, rendering and CNC machining.

When Geomagic Design 16.0 was first announced, milestone features allowing users to convert mesh triangle models (such as from 3D scanners and printers) into useable CAD models was introduced. This means that we can read a file of discrete triangles such as in STL, OBJ or 3DS and convert these into true NURBS based solids for export as IGES, STEP or SolidWorks CAD models using a proprietary "auto-surfacing" technology. Geomagic Design 16.0.2, recently released, adds Boolean to Mesh, trim solid to 3D mesh, and the ability to "snap" to mesh edges in Sketch mode. This provides the mechanical CAD designer with a true hybrid modelling environment unique to Geomagic Design. The following table summarizes these powerful new capabilities.

Scan to CAD - scan directly into Geomagci Design using Sense Scanner
Scan to CAD - users can now attach a low-cost Sense scanner directly into Geomagic Design and begin importing 3D scan data without any need for conversion. Simply click "Launch Sense Scanner" from the main menu. The resulting 3D scanner information will be added to the parametric model history tree as "Mesh" type entities.

Convert to Solid - Mesh entities do not need to remain mesh entities anymore. Reverse engineering time is now greatly reduced with the ability to change a mesh into a solid model with just a few mouse clicks. This functionality was originally discussed in the v16 announcement here: http://cadcam3d.blogspot.com.au/2014/06/geomagic-design-3d-cad.html

This works for both mechanical or organic type mesh models. The results of this conversion process for a sample freeform surface model are shown here to the right.

Boolean to Mesh - Solid model Boolean operations are among the oldest in the direct modelling toolbox of CAD software. Shapes are changed by "adding" or "subtracting" the volume or one solid to another. Geomagic Design extends this functionality by allowing users to specify a mesh as the Boolean tool. Solids may also now be trimmed or cut against an imported or scanned mesh entity as shown below.

Version 16.0.2 also introduced the ability to "snap" to a point on a mesh while in the part sketch mode. The To-Next termination condition type for the Extrude Boss and Extrude Cut operations also now supports the selection of a surface or a mesh. Imported meshes can also now be precisely re-located and oriented against the existing model space using the new Locate Mesh function.

Geomagic Design 16.0.2 reveals the forward vision of Geomagic Design as a true parametric hybrid, capable of using both NURBS solids and triangle mesh models together in the mechanical design process. For a free trial of the new version of Geomagic Design visit the CADDIT website at this link:
