Every now and then I'm really glad Autodesk doesn't take stuff out of AutoCAD. OK, maybe they've taken out one or two things (like the plain old Text command; replaced with Dtext), but I think the Boundary command is a nice little routine that can assist in calculating square footages. Then I got an email from somewhere praising the merits of the Dline command, especially the ability to cut door openings in parallel lines. Little things like that are great to have at your disposal, and both of these features are available in LT!
And in yet another case of discovering applications while I'm "on the job", I was teaching some folks in Cincinnati and found a great application for graphically defining points when making a rectangle. Then finally, I wanted to remind the folks that are following my DesignCenter coverage about a great little feature called "Home". Oldies and Goodies: Gotta love 'em.
If you would like to contact me directly, you can do that also.
Blessings to one and all,
When it comes time to calculate the square footage of a space for fiscal purposes, just let AutoCAD calculate the area. And when you do so, it's best to have a polyline on a separate layer bounding the area to be calculated.
Those of you with AutoCAD 2006 can hover over the polyline to display the object.
Gold Star Tip: Clear the Island Detection check box if you have other objects in the area, such as furniture. Then, when you pick the point, click near the wall. AutoCAD will seek out the nearest object, then track the perimeter of the wall, not the furniture "islands".
Beginning in A2004, the Rectangle command provided an option for Dimension. Cool. What if you want to pick two points to identify one (or both) of the values. In a recent training in Cincinnati I had the opportunity to "explore" that feature. The situation was the need to put an 18" deep bookcase between a fireplace and a wall.
Similar to many other commands in AutoCAD, you can usually graphically specify the points required for a size. Here's the sequence:
Note for A2006 users: The Rotation option of the Rectangle command (displayed after specifying the first point) should be used before using the Dimension option. If you use the Dimension option first, then use the Rotation option to rotate your rectangle, you will need to re-enter your Dimension values. Curious.
If you don't have Architectural Desktop, this is a great trick you can use to create a door opening with a width of your choice. Back in August 2003 I did coverage on the Dline command. Once you have created the parallel lines, however, how do you cut a door opening?
Width - 36
Dragline - L
Offset From - Endpoint snap at the blue dot
Offset Toward - Eastward (with Ortho On)
Offset Distance - 6
Note: Turn off your Osnaps when using this trick. When picking the 'Offset From' point, just use Snap from Endpoint from the Object Snap toolbar or Shift + Right click.
In the June 2005 coverage of DesignCenter I mentioned the benefits of having a 'Master' drawing in which you have your most commonly used named objects. In the August 2005 coverage, I went over how to create a layout and the benefits of using DesignCenter to access to your layouts with the title blocks on a drawing containing your "Plot Sheets".
What I failed to mention in each of those reviews, is the most efficient method of getting to those important drawings: the Home button.
Gold Star Tip: To transfer named objects from one open drawing to another, click the Open Drawings tab, make the necessary selections, and drag them into the current drawing.
Next month I'll wrap up the DesignCenter review!
That explains it! The reason pigeons walk so funny is because their eyes can't focus as they move. The bird actually has to bring its head to a complete stop between steps in order to refocus.
