Combine or subtract 2D shapes 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, in some cases, 2 other methods may be easier.

Subtract shapes with the SUBTRACT command

For example, let’s say that […]

Working with linetype scales

Simple linetypes allow you to apply a repeating series of dashes, dots, and spaces to your objects. Complex linetypes can also include text or shapes.

Recently, a reader said that his linetype was defined as dash-dot but displayed as a continuous linetype. If you have this situation, zoom in and see if you can see […]

Create objects with transparency in your AutoCAD drawing

AutoCAD 2011 introduced the transparency property for objects. Transparency gives you the opportunity to create presentation-ready drawings. You can draw an object that is up to 90% transparent. Here you see some trees filled with a 60%-transparent solid fill.

 

As with other object properties, you should use the Layer Properties Manager to create a […]

Add a solid fill to a closed object

If you need a primer on hatching in general, here are some hatching tips.

Here are the steps:

Now that the trivia contest is set, let’s get into it. […]

Draw a donut (yum!) in AutoCAD

A donut looks like a wide circle with a hole in it but is actually made up of 2 semi-circle polylines. You can use donuts for electronic schematics, as trees or bushes, or as symbols.

Here are the steps to create a donut:

Choose Home tab and expand the Draw panel to find the DONUT […]

Know when unwanted layers creep into your drawing with layer notification

Layers are a big issue when it comes to maintaining drawing standards. Where you work, you may have lots of rules about which layers your drawings can have.

Xrefs can be a problem for drawing standards, because when you attach an xref, its layers come along for the ride. This is especially an issue when […]

Label the scale of individual viewports

A reader asked me how to label the scale of individual viewports when they have different scales. You can use fields to accomplish this.

Here’s a drawing with 2 viewports, one on the left and one on the right. Each one uses a different scale.

Here are the steps to label each viewport:
