Hints & Tips
|Calculating User Scales:
The scales available in the Drawing Setup dialog are the most commonly used for most projects. But, what if you need a scale not listed. like 3/16"=1'0"? Turn it into a ratio and type it in as a User's Scale. Here's how.
Choose Drawing Setup from the Layout menu. Let's use the scale, 3/16" = 1'0". Multiply 16 by 12 to get 192. Then, divide 192 by 3 to get 64. The ratio equivalent of 3/16" = 1'0" is 1:64. Or you can make it even easier by performing the math calculations in the dialog box where you type in the scale. Simply type (16*12)/3 and press Enter.
|For Former ClarisCAD or
If you are used to using special keyboard commands in ClarisCAD, you can set the same key commands in PowerDraw and PowerCADD. Use the Commands function under the Layout menu to set and change key commands to those commands you are most familiar. PowerDraw and PowerCADD also allows you to print a list of all Keyboard commands set. A file named "Keyboard Commands" is created when you assign Commands and is in your PowerDraw or PowerCADD folder. Open this file within any word processing or spreadsheet program and print for a reference sheer.
|Dual Dimensioning with Metric
Many users have expressed a need to have both Imperial and Metric dimensions on a drawing. Additionally, the ability to print only one type of dimension at a time is desired. Try this.
First, turn Edit All Layers OFF.
Set up two layers named: Dim Metric and Dim Imperial (feet & inches)
Ensure the settings for your Dimension tools are currently the desired feet & inches, decimal feet, etc. and the placement for the text is ABOVE.
* Activate the Dim Imperial layer
* Dimension all items required.
* Select All and Copy.
* Activate (move to) the Dim Metric layer
* Select Edit from the Edit menu.
* Change Units to Meters and the Placement to BELOW and click OK.
You now have a drawing with accurate dual dimensioning. If you wish to print only Imperial dimensions, simply hide the Dim Metric layer before printing.
HPGL & Clipping
The file started in AutoCAD as a 3D drawing. The 3D model
was arranged to provide a 3/4 view similar to an isometric drawing.
Once the view was set, the hidden lines were removed. Finally,
the wireframe model was plotted to a disk file in HPGL format.
Associative dimensioning is a term created by the CAD world. Basically, it means that when you resize a dimensioned object, the dimension will recalculate automatically-the dimension is associated with the object it is defining. There are two ways to do this in PowerDraw or PowerCADD. You can simply group the object with its dimension or use Move Points.
Grouping the object with its dimension is the easiest. Once grouped, simply stretch the group and the dimension will change, too. If the dimension must be on a separate layer, and in most cases they are, you can use Move Points.
With Move Points, you can select an area to be moved which contains "points" of intersection. For example, suppose you had a rectangle which was dimensioned on its long side. To lengthen it, you could use Move Points to select one end of the shape (a short side) and one end of the dimension to be moved at the same time. Once selected, you may drag the object to a new length or use the Move command and specify the distance very accurately. When the move is complete, the dimensions will be correct, too.
Experiment with each method of associating dimensions to find the right one for your needs.

AUTOCAD TRANSLATION PROCEDURE FOR CONSULTANTS
Follow these simple instructions to insure that the AutoCAD file you send will be successfully translated into our native CADD format (PowerCADD). Note that there are two file format options, DXF and DWG. Base your choice on whether or not your drawing contains blocks with attributes (i.e., blocks that prompt data input upon insertion). If your file does have blocks with attributes, save file as dxf. If not, save file as DWG. The procedure as given below assumes file will be saved as a dxf file. The procedure for creating a DWG file is identical, except do not set dxfout in preferences.
PROCEDURE FOR PREPARING AUTOCAD FILE TO SEND TO DEPARTMENT OF RECREATION AND PARKS:
1. Open file and save to a temporary file name for backup
1. Open blank AutoCAD drawing.
1. Do save the file in AutoCAD Release 11, 12, or 13.
1. Don't save file in Release 14.
NOTE: Within AutoCAD release 14 is an object class known as ARX. At this time, its effect on the Department's translation software is unknown. Therefore, again, if you are using release 14, be sure to save back to release 13 or 12.

If you are experiencing "jerky" and slower-than-I expected operation of PowerCADD, check to see if you have MacTools. There have been reports that dumping them helps immensely.
Symbols consisting of only one piece cannot be replaced using the Replace Symbol command if placed as a group. If you use one-piece symbols, always place as an instance.
When printing with InfoWave's PowerPlot, always use the plain paper settings.
