Get a head start with a customized template

You should always start a new drawing either from an existing drawing (Application Button, Save As) or from a template.

What is a template?

A template is just like a drawing, but when you start a drawing from a template, the template creates a clone of itself, remaining unchanged. Many people have multiple templates that […]

Cover it up with the WIPEOUT command

Sometimes you need to hide your dirty laundry. The WIPEOUT command lets you do just that. You can create a polygonal outline that is filled with the drawing area’s background color. Everything behind the wipeout is covered up.

You might cover up part of your drawing that represents unapproved designs, confidential data, or anything else.

How to break walls to insert a door

In an architectural drawing, you often need to break walls to insert a door. There are many ways to do this, but here is one way:

Let’s assume that you have a simple wall 4 inches thick. You want to insert a door that is 28 inches wide. You can easily translate these numbers into […]

Choose a useful point style in AutoCAD

Points have many uses in AutoCAD drawings. They are used for construction purposes, to help you find a coordinate. You can find a point using the NODE object snap. Sometimes, they are used as symbols, especially the more visible point styles.

The default point style is a simple dot, but it’s hard to see. Some […]

Combine or subtract 2D shapes with the REGION command to create custom shapes

Sometimes you need to create a 2D profile that is a combination of the basic geometrical shapes that AutoCAD creates. While you might be able to use the PLINE command to create what you want, an easier way might be to combine or subtract simpler shapes.

For example, let’s say that you want to create […]

A different way to create an ellipse or oval

The ELLIPSE command is the usual way to create an ellipse — or oval — but there’s a different way that may be more intuitive for you.

Here are the steps:

Draw a rectangle. Select the rectangle. Start the PEDIT command (polyline edit). Choose the Spline option.

Now, select the oval. This is what […]

Create a circle tangent to a line

Sometimes you want a circle to hug a line perfectly. You could try to eyeball it, but there’s a better way–the tangent options of the CIRCLE command. There are two, TTR and TTT. The TTT option is something of a secret, because it doesn’t appear as an option on the Command line. I have no […]

Create views in your AutoCAD drawing

Do you create large drawings? If so, you probably spend a lot of time panning and zooming. Named views, which are pre-saved displays of part of your drawing, can help! A view can show any area of your drawing at any zoom value.

For the purpose of this tip, I’ll stick to views that you […]

Control the shape of objects when you edit them – Keep an equilateral triangle equilateral

Let’s say that you have an equilateral triangle and you want to make sure that it stays that way, even if you grip edit a corner. Because without any restrains, you can just wreck it, like this:

 

Use Parametrics to control the shape of objects as you edit them

AutoCAD’s geometric parametric feature […]

Create shapes to insert over and over

In AutoCAD, you can create custom shapes using code that resides in a text file. You can insert a shape using the SHAPE command. Custom fonts (especially non-Roman ones) are often created using this shape feature.

Shapes vs blocks

Inserting a shape is similar to inserting a block, so let’s start with the difference between […]
