Today's Tip

Lock your viewports!

The zoom factor of your viewports is crucial because it affects the plotted scale of your drawing. So, once you have set your viewport scale, it's a good idea to lock your viewport so that you don't inadvertently change it. To lock a viewport, select it in paper space by picking on its boundary and then right-click anywhere within the viewport. Select "Properties" from the right-click menu and the Properties panel will appear. In the "Misc" section, click on "Display locked" to activate the pull-down and set the value to "Yes".

2D Drawings from your 3D Models

Over the years, there have been various methods of creating 2D drawings from 3D models in AutoCAD. In the early days, we used export to DXB, a file format that is no longer supported. Then came the FLATTEN command. Now, there's a new command that's better than previous methods.

The FLATSHOT command creates a 2D block object of any view that includes 3D solid objects. There are a number of options including show/hide obscured lines and independent control over the colour and linetype of foreground and obscured lines. Flatshot works by projecting the lines of your current view, not UCS, onto a plane. This is a little more versatile than Flatten and doesn't seem to skew the dimension of the object, which Flatten is notorious for. It also has the advantage of leaving the original object as is. The only downside is that it seems to have problems with perspective views. Parallel projection views work perfectly.

Thursday's Tip

Maximize your work area

You can use Ctrl+0, or go to ToolsClean Screen, or click the faint blue square icon at the very bottom right of the AutoCAD program window to maximize your entire work area. The only thing that will show is your top Pull-down Menu, your Command Line, and/or your Layout Tabs, maximizing the drawing area as much as possible. Of course, you could also turn off the command line and just work with Dynamic Input if you wanted to be even more minimal. These command options work as a toggle, so simply repeat the action to restore the full interface.

If you are a customized keyboard command type of person, the command is CLEANSCREENON and CLEANSCREENOFF so you can easily add it into your ACAD.PGP file complete with your personal Command Alias.

Layer States and Viewports

Did you know that Layer States can be saved and used to control visibility of layers per viewport? If you create and save a couple of layer states within an active viewport, you can then toggle them back and forth without affecting any other viewports, or model space. The changes only occur within the active viewport.

Try this:

Create a bunch of random objects in model space on different layers. Now switch to paper space and create two viewports so that you can see all the model space objects in both viewports. Now activate one of the viewports and open the Express Tools LMAN layer states manager. Create and save a new layer state. Now close LMAN and freeze some of the objects within the viewport. Open LMAN back up and create another new layer state. All of this must be done within the active viewport. You can now toggle back and forth between the two layer states within the active viewport without affecting model space or any other viewports. You can also switch to another viewport and use the same layer states on it, or create new ones.

Easily set properties for multiple blocks in Tool Palettes

Lots of people think that when you have blocks saved in a Tool Palette, you have to Right-clickProperties each individual block to apply custom settings. What if you have 20 blocks and you want them all to have the same setting? Well, just hold Ctrl and highlight the blocks you want within the Tool Palette, then right click on any of the selected blocks to apply global settings.

Also, you can hold the Ctrl button to select your first block, then hold the Shift button to select the last block, then right click on any of the selected blocks to apply a global settings. Makes things much easier than one at a time.

Monday's Tip

Absolute and Relative Coordinates

It used to be very simple. Enter a coordinate and AutoCAD interpreted it as an absolute coordinate. Enter a coordinate preceded by "@" (the at sign) and AutoCAD interpreted it as a relative coordinate. This simple rule changed when dynamic input was introduced and now the interpretation of coordinates is contextual. For example, when you draw a rectangle using RECTANG, the coordinate for the second point is interpreted as absolute with dynamic input turned off and as relative with dynamic input turned on. Really, try it and see.

Fortunately, there's a new coordinate prefix that forces an absolute coordinate, even when AutoCAD decides you want a relative one. Precede any coordinate with "#" (the hash sign) to force an absolute coordinate.

Quick Extrusions with Presspull

As of AutoCAD 2007, there's no need to draw closed shapes before extruding. The Presspull tool will find any enclosed area (just like BHATCH) and extrude it.

Any objects can be used as boundaries; lines, circles, splines, they all work. This makes building 3D solid models much quicker than before.
