Design Master Entities and Text Not Scaling Correctly
When I insert Design Master HVAC graphics and text, they are too big or too small for my drawing. How do I make them scale correctly?​
Design Master HVAC uses the standard CAD system variable DIMSCALE to determine the scale of the current drawing. DIMSCALE is used to size text, leader arrowheads, ductwork lines, and other drawing elements that are not to scale. Design Master HVAC entities are designed to look right collectively as long as DIMSCALE is set correctly.
Do not use the CAD SCALE command to rescale Design Master HVAC entities. The changes will not be saved and will likely be undone later.
Setting DIMSCALE​
To make your Design Master HVAC entities scale correctly for your drawing, you will need to adjust your DIMSCALE value, then update the Design Master HVAC entities on the drawing using the steps outlined below.
-
Enter DIMSCALE at the command line to check the current value.
noteIn almost all cases, DIMSCALE should never be set to 1.
-
Enter the value you think the DIMSCALE should be. See Common Drawing Scales below for a table of common values.
noteHigher DIMSCALE values will make entities larger; smaller DIMSCALE values will make entities smaller.
-
Insert a new scaling entity, such as a ductwork double-line, on the drawing. The block and callout will come in at the new scale.
If the new scale looks right, proceed to the Updating Design Master Entities section below.
If the new scale does not look right, repeat these steps until it does.
Updating Design Master HVAC Entities​
Once your DIMSCALE has been set correctly, to update the size of devices and text already on the drawing, run the Coordinate Drawings and Database command.
If you have inserted any schedules on the drawing, their text and blocks will change the next time you update them.
Ductwork lines and labels will update the next time you draw or recalculate them.
