A variety of tools for measuring the geometry of created models are also included. Additionally, if you’re using RS Components or Allied Electronics as your supplier, the software suite can also tell you how much these components will cost you. For example, DesignSpark Mechanical has a library of various machine parts from different suppliers, and allows users to insert 3D models of these parts into their designs.
Despite being free, it offers many features typically associated with paid (and expensive) CAD software. The ACIS modeler attempts to meet your desired edge length setting, but in some design scenarios, may create an edge length that is less than what you specify as your facet maximum edge length setting, to best accommodate the design.DesignSpark Mechanical is a free CAD software that focuses on mechanical design – that is to say, it provides tools that are most suitable for designing machines and machine parts.
The value you specify is the maximum value for the edges, however smaller edge lengths may be created. The angle is the angle that the chord line makes with a line tangent to the cross-section curve.įacet maximum aspect ratio to change the triangle faceting ratio when you export an STL file.įacet maximum edge length to enter a desired edge length. Check the Merge faces checkbox to seamlessly merge one or more faces.Ĭoarse, Medium, Fine to use the deviation and angle preset values.Ĭustom to use the Deviation and Angle sliders to set the resolution.ĭeviation is the distance between a chord drawn through a curved cross-section of the model and the curve’s most distal point.Solid/surface body: Convert STL triangles into full geometry.Simple mesh: Create a lightweight mesh with no connectivity information between facets.Connected mesh: Create a lightweight mesh with full connectivity information between facets.Set the output of your AutoCAD files to a 1:1 ratio. Save as Black and White: Remove color information from exported designs.Īssociate Dimensions to Geometry: Select dimensions to associate with adjacent geometry. Version: Select the AutoCAD version to set the format of exported designs. The center of the bounding box for the imported data is moved to world origin coordinates (0, 0, 0).
Insert hatch identities as: Select the behavior for hatch identities.Ĭenter imported data: This is useful for AutoCAD files that have models positioned outside of the DesignSpark Mechanical modeling range (+/- 1km). Insert polyface mesh, 3DFace and Solid entities onto drawing sheets as: Select how you want to import these entities onto drawings sheets. Insert polyface mesh, 3DFace and Solid entities into 3D as: Select how you want to import these entities as 3D into DesignSpark Mechanical.
