A common, but difficult task, is to create a threaded bolt. I recently got a request for more 3D tutorials, so here you go. This tutorial assumes an intermediate knowledge of AutoCAD. I rummaged around a box of miscellaneous junk and found this bolt. You can see that it’s about 3 inches long. [...] Visual styles were introduced in AutoCAD 2007. They bring your ability to control how objects look to a whole new level. You can control how faces and edges look, as well as display a background, shadows, materials, and lights — all without rendering the drawing. Visual styles are important when you want to create [...] In 3D drawings, you’ve had some display options for years: wireframe, hidden, and various types of shading. These were the SHADE or SHADEMODE options on the View menu. AutoCAD 2007 introduced a new concept: visual styles. The main difference is that you can customize them to create your own visual style. AutoCAD comes with [...] You may want to draw in 3D, but if you need to deliver drawings in 2D, in several views, how do you convert them? In other tips, “Converting 3D drawings into 2D drawings,” and “Convert a 3D solid to a 2D drawing with a hidden view,” I’ve discussed some methods, but this excellent method [...] One of the nicest new features of 2007 is the ease with which you can change your viewpoint using a poorly-documented keyboard shortcut for 3D Orbit. Press and hold Shift and press your mouse’s wheel (or middle button) to temporarily and transparently enter 3D Orbit. While doing this, use that wheel to drag in [...] The Daily Autocad is a new AutoCAD blog containing in-depth articles each day by a variety of AutoCAD experts in Turkey. Here’s an excellent article on the system variables that effect the display of 3D solids: DISPSILH ISOLINES FACETRES FACETRATIO [...] The SOLIDEDIT command (open the Edit Solids toolbar for easy access) has an option that lets you separate solids. Many people have been confused about this option, because it requires that the solids be non-touching. So aren’t they already separate? It turns out that the UNION command can combine non-touching solids. Think of it [...] You can create 3D objects by adding a thickness to them. These objects function like 3D surfaces. For example, you can create a cylinder from a circle or a box from a rectangle. To add thickness, select the object and open the Properties palette. Choose the Thickness property and change the number in the [...] Surveyors, land-use engineers, and architects often need to create contours that show the elevation of land. You can easily do this using the SPLINE command. First, set an easily visible point style. Choose Format > Point to do this. (This is the PDMODE system variable.) Then use the POINT command to insert the points [...] Readers of my books often ask me how to convert a 3D drawing into a 2D drawing — either to simplify dimensioning or for presentation purposes. Here are three techniques: If your drawing is made up of solids, you should use SOLVIEW and SOLDRAW or SOLPROF, because they provide the most accurate results. SOLVIEW [...] |
