![]() ![]() Otherwise, each separate 2D entity may result in a separate surface entity being created, instead of a single solid body. If you have created a 2D profile using separate entities, you will often need to use the WELD command to turn the entire profile into a single polyline entity before extruding it. For detailed information on what each of these commands does, consult the DraftSight Help documentation. It can also modify existing solid entities by dragging faces. The PUSHPULL command makes it easy to use 2D entities to create 3D entities, either solids or surfaces depending on what you select. The POLYSOLID command is similar to a thin extrude. In the third flyout in the ‘Modeling’ section of the ‘Home’ tab, SOLIDWORKS users will see such familiar commands as EXTRUDE, LOFT, REVOLVE, and SWEEP. Then you can use one of several commands to extrude that profile into a 3D entity. This allows you to create whatever profile you want to serve as the base of your new model. The second method is to start by drawing profiles using normal 2D entities, such as lines, arcs, and circles. Tori are often called donuts, for rather obvious reasons. Options include boxes, pyramids, wedges, planar surfaces, cones, cylinders, spheres, and tori.īelow is an example of a 3D solid created with the TORUS command. The first method is to start by creating a basic 3D entity using one of the commands in the first two flyouts of the ‘Modeling’ section of the ‘Home’ tab. You can start a new model one of two ways. The tools in the ‘Mesh’ section are for mesh modeling, an alternative method to solid modeling. The tools in the ‘Solid Editing’ section allow us to modify existing 3D entities. The ‘Modeling’ section contains tools for creating 3D entities, either from scratch or from existing 2D entities. The ‘Home’ tab of the ‘3D Modeling’ workspace ribbon menu provides easy access to the commands we need to create and modify 3D bodies. Or just make sure the cylinders are on the same layer as the plate before subtracting them. But you could use the EDITSOLID command to match the color of those faces to the new layer. ![]() The final inside surfaces of the holes are part of the blue plate entity, but retained the color of the cylinders which created them. Note the plate and the cylinders were on different layers with different colors assigned before the cylinders were subtracted from the plate. Then you’d subtract the cylinders from the plate, resulting in a single solid entity with holes, as shown in the progression below. ![]() Then you could create several cylinders where the mounting holes need to be. For example, you could create a solid entity to represent a mounting plate. Once you’re happy with the shape, you’re done. Then you just add or remove material as needed. You start by forming a lump of material in a basic shape. But it’s easy to learn and is an excellent tool for many use cases.įor more information about parametric vs non-parametric Boolean modeling, check out the blog Can You 3D Model in DraftSight?įor information about navigating 3D space and changing view settings in DraftSight, refer to DraftSight 3D Modeling Part 1: Views and 3D Navigation The Basics of Boolean Modeling So, this method of modeling is unfamiliar territory for most of today’s CAD users. Parametric CAD applications have tools for working with these featureless imported bodies, but don’t build such models from the ground up. Users of parametric systems like SOLIDWORKS or CATIA may have encountered them by importing models from neutral CAD formats, like Parasolid, STEP, and IGES. Non-parametric models, often known as ‘dumb solids’ lack a feature history. DraftSight Premium, Enterprise Plus, and Mechanical offer users the ability to create non-parametric 3D models.
