Are your drawings bloated for no obvious reason? When you insert a block, is there a long list of blocks that aren’t in the drawing? Ditto for layers?
Oversized drawings load more slowly, take up more storage space, and take longer to save.
Then you need the PURGE command!
Yes, you want slim drawings
Definitions of blocks, layers, styles, and more that aren’t actually used in the drawing make it slow and cumbersome. The PURGE command finds named components that aren’t used and lets you delete them. In a complicated drawing, there can be dozens or even hundreds of unused layers, blocks, text styles, dimension styles, and more.
To start the PURGE command, choose Application Button, Drawing Utilities, Purge or just type purge on the command line. The Purge dialog box opens. Components that have unused items have a plus sign next to them. In this figure, you can see that there are unused blocks, dimension styles, layers, and linetypes. You can expand these items to see what you can purge.

With AutoCAD, you can create a short animated walkthrough video of your architectural model that can help you in presenting your ideas in a more creative way. Using short animated walkthroughs you can simply convey a lot of information without using many tools or drawings and even a non-technical person will be able to understand your design ideas.

By default design, AutoCAD’s line is a single entity. This singularity of the line allows it to be treated as a simple drawing element without the leverage of more complex types. However, for those of you who may require such a feature, there is a way other than grouping different colored lines into one.
As said, by default the line is a simple element hence to replicate functionality not built-in, we need to setup the proper environment before we proceed with the actual development. See the below screenshots for a step by step explanation of the prerequisites of sawing multicolored lines.
Step 1: Command: MLSTYLE. Use the command MLSTYLE to access the Multi-Style menu. When you press enter, the dialogue box should open up.
Step 2: View current profiles
By default a “Standard” profile is defined for regular line drawing. This is also set to the current profile in selection. At any time, this one profile will be available if there are no other. Create a new profile as shown below.Step 3: Create a new Multi-Style profileContinue reading How to create multicolored lines in AutoCAD
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 layer and specify the transparency as a layer property. Here you see a red layer that is 75% transparent.
Transparency is pretty useless for the line that delineates an object, but is quite useful for a solid fill hatch or a gradient. Here you see the effect of a red 75%-transparent layer on top of an opaque blue layer. The result is purple at the point of overlap.
To create an object with a partially transparent solid fill, follow these steps:
Open the Layer Properties Manager (the LAYER command).
Click the New Layer button and name the layer.
In the Color column for that layer, click the color swatch and choose a color.
Click in the Transparency column for that layer to open the Layer Transparency dialog box and type a value between 0 (completely opaque, the default) and 90 (mostly transparent). Then click OK.
Make any other changes that you want to the layer’s specifications and close or collapse the Layer Properties Manager.
From the Home tab> Layers panel< Layer drop-down list, choose the new layer to make it current. (You can also do this after the next step.)
Draw a closed object.
Choose Home tab> Draw panel> Hatch.
In the Pattern panel, choose Solid.
At the Pick internal point or [Select objects/seTtings]: prompt, pick inside your closed object.
Press Enter to accept the solid fill and end the command.
Do you use transparency in your drawings? Why or why not?

One common question that I get is how to access AutoCAD commands quickly.
AutoCAD is 30-year-old software. People used it before it ran on Windows. It was designed to run on different operating systems and different standard interfaces that are used today. That’s why there are many methods to access AutoCAD commands. One method may be faster in general, but another method can be faster when doing other tasks.
For example the command line is faster for most AutoCAD users for activating a line command. But Function keys are faster to toggle Ortho mode. It would be better for you to know all methods, so you can decide which one works best for you.
So let’s explore all the methods that you can use to execute AutoCAD commands and see how you can use them effectively.
The ribbon was introduced in AutoCAD 2009. If you learn AutoCAD after this version, you probably use this as primary method. I found that many occasional users also like ribbon.
Many AutoCAD veterans don’t like ribbon, because it’s a big change from toolbar to ribbon. It feels slow (personally I feel it becomes better in later version) and take too much screen real estate.
This is the most apparent way to activate a command in latest version. Even if you’ve never seen AutoCAD in your entire life, you know you can activate a command from here.
This is a fairly simple wheel with a center tube for an axle/pole, a rim, and 6 holes. You can create a 3D wheel like this entirely with cylinders! Watch this 9-minute video tutorial and follow along to create it from scratch yourself.
You’ll learn how to:
Create cylinders: Cylinders are an obvious choice for a wheel and are often used in mechanical drawings.
Set the workspace to 3D Modeling: The 3D Modeling workspace gives you all the tools you need for 3D work; you won’t find them in the default workspace
Use the SUBTRACT and UNION commands: These are called Boolean commands and they let you carve out holes and combine objects
Change the visual style to check your work: The default wireframe makes some work easier, but it’s really hard to tell if you made mistakes. This image uses the Conceptual visual style, which makes everything very clear.
and a few more tasks.
The basic concepts are applicable to many types of 3D models.
Here’s the video. Let me know in the comments what you think! Do you have suggestions for drawing this differently? Did you run into problems? And use the Share buttons below the post to share with your colleagues so they can practice it, too!
If you have LOTS of drawings and want an easier way to find them, you can give them properties that you can search for using Windows Explorer. You can even create custom properties. You’re supposed to be able to search for these properties in the Design Center and Content Explorer, but neither one worked for me. Of course, you can search for drawings by name, but what if you don’t know the name? What if you don’t know when it was last modified? Drawing properties can help.
Create the drawing properties
To specify drawing properties, choose Application Button, Drawing Utilities, Drawing Properties. This opens the Properties dialog box. It has 4 tabs:
General: This is just for your information. You can’t add properties here.
Summary: Lets you specify a title, subject, author and add keywords. You can separate multiple keywords with a comma. You can also add comments and a hyperlink base to use for relative hyperlinks.
Statistics: This is also for information only and tells you when the drawing was created and last modified, who last saved the drawing, the revision number (if any), and the total editing time.
Custom: To add custom properties, click the Add button. Then type the custom property name and value and click OK.
Of course, you want to use properties that will help you find the drawing. You might add properties for clients, discipline (architectural, mechanical), geographical location, etc.
Search for a drawing by its properties
To find a drawing by its properties, open Windows Explorer. Then follow these steps:
In the left pane, click where you want to search. It can be a drive or a folder.
Type a search term in the search box at the upper right. I searched for “chapter,” which was my property. I didn’t have to know its value.
At the top, choose Advanced Options and check File Options.
That found the drawing that contained a custom “chapter” property, as you can see in the figure below.
Why not Content Explorer or Design Center?
I tried searching in the Content Explorer and the Design Center and came up empty. What is your experience using drawing properties? If you don’t use them, would they help you? Leave a comment. And please share this post using the Share buttons below — maybe someone else will find it useful.
First set the layer that you want to use for your solid fill. The hatch will go on the current layer.
On the Home tab in the Draw panel, click Hatch. The Hatch Creation tab appears.
In the Pattern panel, choose Solid.
If you have one closed area, you can just click inside it to pick an internal point. If you want to select an object, you can click Select in the Boundaries panel, as you see here. Then press Enter to end selection.
Press Enter to end the HATCH command.
Turn fills on and off
I thought I’d tell you about the FILL command. This command (which controls the FILLMODE system variable) can show or hide solid fills. Its original purpose was to help your computer run faster if you had lots of solid fills. Nowadays, that isn’t usually a problem, but turning off solid fills can sometimes help you see your objects more clearly.
Just type fill and press Enter. Then choose On or Off. Type regen to see the change.
Warning! If you turn off fills, they don’t plot! So be sure to turn them back on if you turned them off for ease of editing.
The SOLID command that isn’t a solid
The SOLID command is an old command that’s rarely used now because using the Solid pattern of the HATCH command is much easier. It was the original way to fill a closed area with a solid fill, hence the word “solid.” It’s not related to 3D solids, although if you create an object with the SOLID command and give it thickness, it creates surfaces with tops and bottoms.
You can only use SOLID for straight-edged objects. First create the object and turn on object snap for endpoints and whatever else you’ll need. Type solid and press Enter. then start specifying points in a zigzag fashion. After the 4th point, you’ll get prompts for the 3rd and 4th points over and over until you’re done. You continue to create adjacent triangles in this way until the shape is solidly filled. Press Enter to end the command.

AutoCAD offers several types of text or annotation objects. Some are for dimensions or at the end of leaders, for example. But the most common type is text that you use as labels–and there are 2 types. The original type was called single-line text (or Dtext). When you use single-line text, every line is a separate object, ideal for short labels.
But many drawings require lengthy annotation in paragraph form and for that reason Mtext (multiline text) was introduced many years ago. You can format text almost any way you format text in your favorite word processor.
But sometimes, you have single-line text that should be Mtext, or vice versa. I have some old drawings that were created before Mtext! Here are 2 ways to convert between text and Mtext.
Convert single-line text to Mtext
Here’s some text in an old drawing that is single-line text. You can see that one of the lines is selected. It’s a plat description and of course, it should be Mtext. To convert it, use the Express Tools command TXT2MTXT. From the ribbon, choose Express> Text> Convert Text to Mtext.
At the Select objects: prompt, select the text objects that you want to convert. Usually, a window works best for selecting. After all, you don’t want to have to select each line of text individually!
If you press Enter instead, you get the Text to MText Options dialog box, shown here. By default, the command sorts from the top object downward and tries to word wrap the Mtext that it creates. You can choose to order the text by the order you selected it.
One cool feature of TXT2MTXT is that if you select the text objects first, the command executes without further input — very efficient! Also, the command does a true conversion by deleting your old single-line text objects.
You can see that you now have a single MText object.
Convert Mtext to single-line text
Sometimes, you need to reconfigure your text because it won’t fit anywhere as a paragraph. In these situations, you can convert the Mtext to single-line text.
One way to convert Mtext to text is to copy and paste. Double-click the Mtext to open the Mtext editor. Select the text and copy to the clipboard. Then close the editor.
Start the TEXT command. Specify the start point, height and rotation angle as usual. You’ll then see a small box and cursor. Paste from the clipboard and press Enter to end the command. The text becomes all one line (which can get pretty long if you have a lot of text). Then delete your Mtext object.
Or you can simply explode the Mtext. This method keeps the line wrapping. It all depends on which result you want. A plus is that you don’t have to delete the original object.
