This fact somewhat limits its use to 3D printing, CNC preparation and early-on design conceptualization. Similarly, Mechanical only exports AutoCAD (DXF), OBJ, STL, XAML, JPEG, and PNG file formats, along with 3DPDFs. Similarly, Fill is used to create surface patches and Combine contains all the common boolean functions. For example, Pull is used to extrude, fillet, sweep, shell, and scale geometry, while Move can be used to reposition, rotate, pattern or mirror 3D features or 2D sketch components. Within each of those commands, however, reside many of the functions experienced CAD users would be familiar with. For example, using Mechanical is similar to Sketchup’s sketch and extrude technique, but focuses on four basic modeling commands: Pull, Move, Fill and Combine. To help spread the use of 3D CAD design, electronics distributor, Allied Electronics, in partnership with SpaceClaim, has released DesignSpark Mechanical, a no-cost direct modeling 3D solid geometry creation and assembly tool.īased on SpaceClaim Engineer code, DesignSpark Mechanical isn’t so much a “dumbed-down” or feature limited version of the comprehensive modeling package but a rearrangement of the interface to simplify it for new and/or casual users, say SpaceClaim reps. Typically, learning to use 3D CAD software efficiently requires a sizeable investment in time and money-two factors that keep many drafters rooted to their familiar 2D packages and many would-be designers at arms length from complex 3D applications.
