Utility Dim Adjustment
Command line: DIMADJUST
Adjusts a dimension when the pipe segments of a particular run have been adjusted or modified with the ISO flag command. For more information, see ISO Flag. This command works with the associate dimensioning setvar DIMASSOC on. The command also adjusts the pipe’s stored xdata length. This is performed by using the dimension to adjust the pipe’s xdata. You can adjust the pipe with Dimension option, or adjust the dimension with Pipe option. Both options of this command read and write fractional characters used with the dimension routines.
Options
Dimension
Adjusts the pipe to match an existing dimension. Select the dimension, then select the pipe’s centerline.
Pipe
Adjusts the dimension to match the stored length in the pipe’s xdata.
Line
Adjusts the pipe distance to match the length of a line that you select. CAD platform dimension lines stop at the back of the arrow, so they are not typically a good choice for this option.
Pick reference points
Adjusts the pipe distance based on two reference points that you select. This is the most commonly used option and can be used to pick each end of a pipe.
For this option, the following prompts requests the selection of the pipe(s) that were adjusted. Selection can be made by crossing, window or individually selecting the centerlines. Other components which might have been selected with crossing or window are simply ignored. This only detects adjusted pipe.
