Create a single part model which consists of your 2D layout sketch. Tutorial Common Origin Position Independentġ. To avoid crowding the highest-level skeleton with too many sketches and features, derive additional skeleton parts from the master skeleton to represent or add details for sub-assemblies. To change the assembly, edit the skeleton part, and then update the assembly to reflect the changes in all components affected by the skeleton part. Repeat these steps for all components defined in the skeleton model. Continue to model the primary features of the component from the derived geometry. The new component is grounded at the assembly origin.ĥ. Select the sketches, work geometry, features, and bodies to derive into the component. Use Make Part, from within your layout, to create a component in your target assembly. Be sure to name the parameters appropriately and mark them for Export.Ĥ. Establish all critical parameters in the skeleton part. Include construction surfaces, work features, and even solid geometry to be used as feature terminations or reference geometry during assembly component modeling.ģ. Position the sketches to reflect the position of the components in the assembly.Ģ. These sketches reflect the layout of the assembly components. Create a single part model, called the skeleton, consisting of base sketches. Additional creation of skeleton sketches.Reference common connections or critical locations from a single file.Solids define volumes for final assembly as a single part or for defining subareas of the design. Parameters define important values for part size, angles for placements, and other known values for the design.Ĥ. Work geometry defines important connection points, axial directions, and work planes that define assembly levels.ģ. Sketches define the concept of the final product or use as a layout of different areas of the assembly.Ģ. The following is typical information created in a skeleton file:ġ. Then you use it as a base for most of the subassemblies and parts that make up the assembly.Ī skeleton file can contain any type of element in any combination. In the skeletal modeling method, you put all known factors into a skeleton file. Also use the position independent workflow with sketch blocks to create kinematic layouts Make Components translates sketch constraints to equivalent assembly constraints to achieve the kinematic behavior. With position independent components, changes to the position of sketch geometry in your layout do not require component revisions. Use the position independent workflow to derive shape only. Note: Use the common origin workflow to derive shape and position to your new components. Although many variations of this technique exist, the basic workflows are as follows. Skeletal modeling (a type of top-down design) is a technique that facilitates centralized design criteria and creates components that reference those criteria.
