On Wednesday, August 10th I will be giving the Keynote Address at the National Collegiate CADD Conference being held at Iowa State University; quite the honor, to be sure. I will also be presenting a breakout session of tips and a day long venue of A2006 cool features. Just in case I don't make it to all of the topics I would like to cover, I wanted to put my overflow content out here for all to enjoy.
There are a lot of "automatic" things in AutoCAD these days. The automatic update of a field is of particular interest and the application I have highlighted this month is pretty amazing. One of the other cool things I learned over the last few weeks was how to globally update the path of the source file used for the entire block collection of a palette (compliments of Alan Henderson of ResourceCAD International, www.resourcecad.com ). And I also discovered a way to globally update the Prompt for Rotation property of all the blocks in a palette. What a time savings that one is!
And finally, I have been remiss in not outlining the fundamentals of creating a layout. They have been around for years and I just wanted to give a fundamental overview of the elements of a layout in an effort to illustrate yet another area in which DesignCenter can be used to increase your productivity. There should be something in here for everyone. Enjoy!
If you would like to contact me directly, you can do that also.
Blessings to one and all,
You will really love this one. Wouldn't it be cool to have the area of a closed polyline update when the polyline itself changed? One method of changing the shape of a polyline is the Stretch command. When you have a field associated with the area of the selected object, when that object changes, you just update the field.
In the following example I traced the perimeter of a room with a polyline on a separate layer.
Note: The variable Fieldeval specifies when a field is to be updated. (See) The default value of 31 specifies that a field is to be updated when its associated information is modified.
To give credit where due, I found this trick on Shaan Hurley's website, http://autodesk.blogs.com/between_the_lines. His site has lots of links and AutoCAD tips and he's pretty diligent about updating his site several times per week.
For those of you doing civil engineering…
or creating golf courses in your spare time…
that field trick is a great way to keep track of the square footage of the area of a closed spline during the design phase of your project!
In AutoCAD 2005 we were given the ability to assign a Prompt for Rotation property to blocks on a palette. The bummer is that the default setting is No. Now what person in their right mind wouldn't want the ability to rotate the block when it was placed on the drawing?
Answer: The person far smarter than myself suggesting that the prompt for rotation would potentially "adversely affect" a dynamic block with a Rotate Action assigned to it. Point made. That still left me with a lot of blocks on a palette that were all set to 'No' for their Prompt for Rotation.
Solution: Hold down Ctrl, then click on a block on the tool palette. This effectively disables the process of placing the block in the drawing that usually occurs when you click on a block. That block is now selected.
Next, hold down Shift and click the last block in the column that you want to select (or use Ctrl and click individual blocks on the palette). If you have added Text or Separators (palette features available in A2006 only), use Ctrl and click those elements to deselect them.
Now right-click on any of the selected blocks and click Properties. In the Properties window, set the Prompt for Rotation to Yes, then click OK. All of the selected blocks now have their Prompt for Rotation set to Yes! How cool is that?
Some of you may be asked to create or customize tool palettes for your customers or perhaps you're the CAD Manager and have been working on your company's tool palettes at your home office. Regardless of the situation, when you add a block to the tool palette the source file is included in that block's properties. And in the current scenario, that source file just happens to be on a system other than where it will be when finally install your custom palette.
Quandary: You now have a couple dozen blocks on a palette (or palettes) with source files you will need to change once you turn it over to your customer (the Space Planning Dept. at CalPERS, for example) or your own corporate network. Can you do it globally? Yep.
I posted this question to the CADTutor Forum, and received an immediate response from Alan Henderson, one of the talented members of the support team at Resource CAD (www.resourcecad.com). Check it out.
When you copy the .XTP file onto the customer's system and Import the tool palette, the source drawing of the blocks will be recognized. Don't forget, of course, to bring along the .DWG file where the blocks live when you configure the new palettes.
One of the most powerful features of the DesignCenter is the ability to access named objects (Layer, Dimension Styles, Text Styles, etc.) from any drawing (see The Basics in June 2005). Among that collection of drawing features in DesignCenter are the Layouts of a drawing.
So consider this: Rather than putting all of the title blocks on their respective layouts and including those in your template (.DWT; see February 2004), how about having a separate drawing that contains only layouts. That way you access DesignCenter for the layouts as you need them.
Before I can show you the benefits of accessing Layouts from DesignCenter, I need to give you the fundamentals of creating a layout; something I should have done months ago. There are four essentials to configuring a layout: The device to which you will be plotting (a printer or plotter or in the case of the following example, a DWF driver), the paper size, a plot style table (usually monochrome or color) and the name you want to assign to the layout tab for easy recognition.
These fundamental elements are found in the same place for A2000-A2004. In A2005 & A2006, they re-arranged the "furniture" and shuffled their position, but the elements remain the same. Even for LT.
A2000-A2004: Depending on your current settings in Options, you may get the Page Setup dialog box. If you do, go to step 4 below. If you don't go to step 3 below.
A2005-A2006: Depending on your current settings in Options, you may get the Page Setup Manager dialog box. If you do, click Modify to go to the Page Setup dialog box. If you don't go to step 3 below.
A2005-A2006: Click Modify to go to the Page Setup dialog box.
A2005-A2006: Select DWF ePlot.pc3 from the Name list of devices.
A2005-A2006: Select ANSI B (17.00 x 11.00 Inches) from the list of Paper sizes.
A2005-A2006: Click OK, then click Close from the Page Setup Manager to see the layout settings.
The viewport rectangle now appears smaller since the original page size was probably an A size and you have configured the layout to a B size (17 x 11).
A2004-A2006: Open DesignCenter. Depending upon your OS, you may need to go to C:\Documents & Settings \Yournamehere\Desktop to see the CT_Aug Plot Sheets.dwg file.
Like I said at the beginning, those are the very fundamentals. At least you now have a better handle on using Layouts from the DesignCenter and you may be making some mental leaps on how to optimally implement this approach to your title blocks.
Next issue we'll look at even more applications for DesignCenter!

However, running a site like CADTutor does cost money and you can help to improve the service and to guarantee its future by donating a small amount. We guess that you probably wouldn't miss $5.00 but it would make all the difference to us.
Note from Michael: I want to thank all of my customers for continuing to retain my training services (some for over two decades!) and let you know your donations do not go to me personally, but to the ongoing maintenance of the CADTutor ship as a whole and to support the yeoman efforts of my friend and CADTutor captain, David Watson, to whom I am grateful for this monthly opportunity to share a few AutoCAD insights.
