Dimensioning
Changes the length, measurement and guide properties of the selected dimension line.
If you want to modify the line style or the arrow style of a dimension line, choose Format - Line.
A Dimension Line is always inserted on the layer called Dimension Lines. If you set that layer to invisible, you will not see any Dimension Line in your drawing.
Line
Sets the distance properties of the dimension line and the guides with respect to each other and to the baseline.
Line distance
Specifies the distance between the dimension line and the baseline (line distance = 0).
Guide overhang
Specifies the length of the left and right guides starting at the baseline (line distance = 0). Positive values extend the guides above the baseline and negative values extend the guides below the baseline.
Guide distance
Specifies the length of the right and left guides starting at the dimension line. Positive values extend the guides above the dimension line and negative values extend the guides below the dimension line.
Left guide
Specifies the length of the left guide starting at the dimension line. Positive values extend the guide below the dimension line and negative values extend the guide above the dimension line.
Right guide
Specifies the length of the right guide starting at the dimension line. Positive values extend the guide below the dimension line and negative values extend the guide above the dimension line.
Dimension line below the object
Reverses the properties set in the Line area.
Decimal places
Specifies the number of decimal places used for the display of line properties.
Legend
Sets the properties of the dimension text.
Text position
Determines the position of the dimension text with respect to the dimension line and the guides.
The AutoVertical and AutoHorizontal checkboxes must be cleared before you can assign the Text position.
AutoVertical
Determines the optimal vertical position for the dimension text.
AutoHorizontal
Determines the optimal horizontal position for the dimension text.
Show meas. units
Shows or hides the dimension measurement units. You can also select a measurement unit you want to display from the list.
Parallel to line
Displays the text parallel to or at 90 degrees to the dimension line.
