Create or use STEP boundary-rep geometry. The most common use of STEP is to describe the CAD mathematical shape as a series of surfaces trimmed and connected by shared edges. STEP always describes products, so the shape information appears as a property of a product, often the only property. Tolerances attach to geometry to annotate the design with PMI information.
- Make Geometry: Make a simple brep solid box with product structure. Shows the basic elements of STEP geometry.
- Make Plate: Create a solid model of a polygonal plate with some circular or polygonal cutouts.
- Make Tolerance: Read an existing data file with geometry for a block and hole, then apply dimensions, datums, and tolerances to the faces.
- Mesh an Assembly: Create and print meshes
- STEP to STL: Mesh and print as STL
Create or use STEP assemblies. Assemblies have a product side and a shape side. The product side describes the structure from a bill-of-materials point of view, while the shape side describes the geometric positioning of all components.
- Make Assembly: Create a STEP assembly with geometry and the assembly relations between the product structure and geometry.
- Walk Assembly: Traverse the products, shapes, and relations in a file to print the assembly structure and key objects.
- Add PDM props: Read a STEP file and add some sample PDM attributes like a release date, owner, and an approval.
While shape and assembly structure are the most common use, the STEP models can describe many different aspects of product design, and STEP-NC goes beyond that to describe manufacturing process that makes a design.
- Make Hole Feature: Create a round hole feature with the parametric description (circular profile swept along a linear path) and a flat bottom condition.
- Make Property: Create a product with the common STEP structure needed to add descriptive and measure properties.
- Make Toolpath: Construct a STEP-NC toolpath, speed, and feed data.
