Do objects with thickness have tops and bottoms?

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 […]

Create contours from elevation points

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 Home tab> Utilities panel drop-down, Point Style in the Drafting & Annotation workspace. (This is the DDPTYPE command or PDMODE system […]

Converting 3D drawings into 2D drawings

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 […]

Convert a 3D solid to a 2D drawing with a hidden view

Koyilada Venkata Rao sent in this tip for converting a 3D solid to a 2D drawing. His tip explains how to create a hidden view, but you can create a wireframe as well. It uses the SOLPROF command to create a profile. By transferring the results to another file, you get a solely 2D drawing.

Carve a solid with a surface

One of the exciting new features of AutoCAD 2007 was to allow you to use the SLICE command to carve a solid with a surface. Previously, SLICE was limited to planes. Because you can create such interesting surfaces, you can now carve out solids to make solids that appear molded.

Follow these steps:

Create the […]

AutoCAD tutorial: Draw 3D walls with polysolids

Polysolids are like 3D polylines that come with a thickness. You can use them to quickly create walls based on a 2D floor plan. The result is a swept solid. You can also draw polysolids without a 2D floor plan, by just specifying points, but here I use existing objects as a basis. Follow these […]

AutoCAD Tutorial: Create a mesh solid jar

This tutorial requires AutoCAD 2010 or later and shows how to create a mesh solid jar.

Start a new drawing using acad3d.dwt. Switch to the 3D Modeling workspace by choosing it from the Workspace Switching pop-up menu on the right side of the status bar or next to the Quick Access toolbar at the upper-left […]

3D Tutorial: Draw a glass

This tutorial will create a drinking glass. I used the measurements of one that I had in my kitchen. I recommend using the 3D Drafting workspace

Draw a circle with a radius of 1.25. On the View tab, click the Views drop-down and choose SE Isometric. Start the EXTRUDE command. Select the circle and […]
