![]() Stay tuned for more DraftSight design and modeling blogs at Īlso please visit our blog for our other blog articles pertaining to DraftSight:ĭraftSight for the AutoCAD User – Laura Nickerson This will leave me with the completed body. This is what all of the bodies that will be subtracted from the primary body look like.įor the last step I will use the Subtract command to remove the primitive solids used for the cuts from the primary solid. Next I will create a Box 40mm X 3mm X 40mm for the undercut and add 8mm fillets. Next I will need to create two cylinders at the center of the vertical boss, one 18mm Dia X 5.68mm deep and one 9mm Dia X 10mm deep. To start I will activate the layer for the primitive negative bodies and create two cylinders offset from the corners by 15mm from the outside edge and 10mm from the top edge of the base. Now I will begin to create the primitive solids used for the cuts. Next I will move it to the Combined solids layer by activating the layer and moving the body to it. Now after selecting the three solids and completing the command, if I hover over the solid it looks like this. It’s time now to combine the three solids into a single 3D shape. ![]() Here are the separate rendered solids (there are three). ![]() Next I will create the last of the positive primitive shapes by adding a cylinder at the midpoint of the edge of the vertical rectangle. This will be the rectangular portion of the vertical tombstone shape. Next I will create another box 40mm x 10mm x 30mm located on the front face of the base body at 0, 30, 0. I will use the Fillet tool to create 8mm fillets on the cornersĬhanging the render to wireframe makes it easier to collect the edges. Next I will create a Box, 40mm X 150mm x 10mm with the bottom left corner on the Origin. I will start by setting up the layers to organize my 3D shapes. Here is a drawing of the part I will be creating: In an earlier blog - Introduction to Basic 3D Shapes in DraftSight - I demonstrated the methods for creating the basic 3D shapes using DraftSight Premium or DraftSight Enterprise Plus.įor this demonstration I will be using the basic 3D shapes from the 3D Modeling Workspace to create over-lapping solids, which I will combine or subtract to achieve the desired shape. This method may be used with any version of DraftSight. ![]() Then using the Extrude command to create a solid body. If you find a performance issue, you may need to reduce your resolutions to a level that does not effect the performance of DraftSight, but provides a fair resolution.In my last blog - Using Sketched Contours to Create 3D Extrusion in DraftSight - I demonstrated a method for creating a closed contour with a polyline or with sketch entities and the Weld command. Please note, that if you change the resolution to a higher setting, this may reduce the performance of DraftSight as more effort is required from the computer to calculate the accuracy of the curved geometry. The issue is not due to the output from CAD packages such as SolidWorks but the resolution of DraftSight. This issue does not just effect circles, but may also effect arcs, ellipses, splines and other curved geometry. With the 2D model open in Draftsight, type in ‘VIEWRES’ in the Command Window located on the bottom of the DraftSight User Interface, say no to fast zoom and then type in a higher resolution value between 1 and 20,000 (with 1 being the lowest setting) you will notice the rasterised circle becomes smoother and round. When using DraftSight to view DXF’s, DWG’s or if you are using as a 2D drawing package, you may notice some circles that look like a ‘fifty-pence piece’ – heavily rasterised. DraftSight is a free 2D CAD package available from Solid Applications.
