AutoCAD Tips & Tricks

Today's Tip

Moving vertically in 3D

Moving objects vertically always used to be a bit of a chore with AutoCAD, usually involving some relative coordinate entry for the Z direction or maybe the .XY filter. Fortunately, AutoCAD 2007 introduced a new command that makes moving objects vertically a snap.

You'll find the 3D Move button on the Dashboard or Modify3D Operations3D Move from the pull-down menu.

As with the normal Move command, you're first prompted to select objects. Once a selection is made, the cursor changes to the move grip tool. Now, pick any point on the base plane to fix the move grip tool at that elevation. Next, hover your cursor over the blue axis handle (Z axis) until it changes to a gold colour and left-click. This has the effect of constraining movement in the z direction. All you need do now is enter the distance you want the object to be moved or use the mouse to pick a distance.

Dashboard's hidden depths

Did you know that there's more to the Dashboard than is apparent on the surface? When I first started working with it, I thought, "wouldn't it be great if all the 2D drawing tools were on there as well". Fortunately, they are. All you need to know is how to get at them.

Simply right-click on any part of the body of the Dashboard (not the vertical title bar) and select "Control panels" from the menu and then click "2D Draw control panel". You should see that the Draw and Modify toolbars are added as a new panel to the top of the dashboard.

Now you can keep your work area cleaner when using the 3D Modeling Workspace.

AutoCAD Alias Editor

If you're new to AutoCAD or even if you're not and you find it difficult to remember all the keyboard shortcuts to your favourite commands like L for Line and C for Circle or even 3DO for 3DOrbit, then you need to know about the AutoCAD Alias Editor.

Enter ALIASEDIT at the command line and AutoCAD will launch a tiny application window that lists all the shortcuts in alphabetical order. As this is a seperate application, you can keep it minimised on your taskbar until you need it for reference.

Essentially, this editor simply lists the contents of the acad.pgp file where all the command aliases are stored. Those of you who are a bit more adventurous, may even like to use the Alias Editor to create your own aliases or edit existing ones.

Extend/Trim commands

While in the middle of either of the Trim or Extend command, you don't have to exit out of one to start the other; they're virtually the same command. So if you're using Trim, and need to Extend, simply hold down the SHIFT key and it will convert to the Extend command, and vice-versa.

DWG TrueView

Quite often, you need to share your AutoCAD drawings with co-workers or others who don't have a copy of AutoCAD. In the past, this meant either providing drawings in DWF or buying some special viewing software. Well, now you can share your drawings files in DWG format for free.

Autodesk's own DWG TrueView application is free to download and install, and it looks just like AutoCAD. Co-workers without AutoCAD can not only view your drawings but they can plot them too and publish them as DWF. See here for more information.

Tuesday's Tip

Selection Preview Cycling

Making positive selections is much easier now that AutoCAD highlights (previews) objects as you mouse over them. However, it can still be difficult to select the right object when drawings become complicated with lots of overlapping objects. Fortunately, AutoCAD allows you to cycle through all the overlapping objects under the cursor.

All you need to do is hold down the Shift key and then repeatedly hit the Spacebar (Shift + Space). Each object under the cursor will be highlighted in turn and you can easily pick the one you want.

You can use a similar technique to cycle through sub-objects such as faces and edges on 3D Solids. To cycle through sub-objects, hold down the Control key and hit the Spacebar repeatedly (Ctrl + Space).

Monday's Tip

Auto-repeating Commands

Sometimes you need to repeat a command lots of times and it can be a bit tedious doing the usual Right-Click and Repeat… or even using the Enter () key on the keyboard. It would be really useful if you could just keep a command auto-repeating until you hit the Escape (Esc) key. Well, you can. All you need to do is make a small change to the CUI.

For example, say you want to draw lots of circles and have the circle command auto-repeat so that you can just pick center, radius, center, radius etc. Here's what you do:

1. Select ViewToolbars… from the pull-down menu to display the CUI dialogue box.
2. In the "Customizations in All CUI Files" section, click on "Toolbars" and then "Draw" to reveal the Draw commands, and then click "Circle".
3. The Properties area now changes to display the Circle button properties and under the "Macro" heading, you will see the macro used to start the Circle command. By default, this macro is: ^C^C_circle. To cause the Circle command to auto-repeat, simply add a "*" before the existing macro. Once edited, your macro should look like this: *^C^C_circle.
4. Now click the "OK" button to save and return to the drawing.

Try the circle command and see what happens.

This technique can be used with most commands. For example, if you are doing a lot of dimensioning, you could auto-repeat the Linear Dimension command so that you can draw all your dimensions without breaking stride.
