Reverse a polyline in AutoCAD


This is a guest post by Will Forty, who runs I recommend that you visit Will’s website and sign up for his newsletter to get blog posts like this.

Probably my favourite entity in AutoCAD is the polyline. However, there have been a few things in the past that I’ve found somewhat annoying, [...]

Create a polyline from the boundary of existing objects


Sometimes you need to create a closed polyline from several existing objects that don’t meet end to end.For example, let’s say that you want to draw a polyline from the inside border created by the rectangle and two circles.

The BOUNDARY command is a very easy way to do this.

Start the BOUNDARY command [...]

Divide up a polyline or spline


Ever need to place an object evenly along a polyline or spline? For example, you may want to divide a plat into equal sections or 40′ sections. For whatever reason, you can do this easily using the DIVIDE or MEASURE command.

These commands are especially useful when your object is a curvy polyline or [...]

Speed up your work with command aliases


When I give instructions, I usually provide ribbon access instructions for commands, but the quickest way to work is to type command aliases on the command line. You just need to know them. Print out this list and keep it by your computer for a couple of weeks until you learn them. You’ll be [...]

I rummaged around a box of miscellaneous junk and found this bolt. You can see that it’s about 3 inches long.


Do objects with thickness have tops and bottoms?

To add thickness, select the object and open the Properties palette. Choose the Thickness property and change the number in 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 [...]
