When adding sketch dimensions from one circle or arc to another, a dimension will be added between the center points by default. However, by selecting the circle and/or arc when adding the dimension, the properties for that dimension now have options to change where the extension lines display.
These options can be changed at any time for dimensions that fit this criteria by editing the Dimension Properties in the Property Manager.
In addition, if you know the desired orientation of the dimension prior to adding it, you can ‘set’ the Arc Condition properties simply by the way you add the dimension to the sketch.
Below is a dimension added by selecting the two circles and placing the text. Switching to the LEADERS Tab in the Property Manager shows how the Extension Lines can be changed.
Setting the Arc Condition on Insert
WHILE adding the dimension, if you hold SHIFT, you can Snap to the Minimum, Center or Maximum Arc Condition depending on what part of the circle/arc you select.
|– While still holding SHIFT, if the cursor position moves outside the ’90 degree window’, the ARC CONDITION changes to CENTER.Click to capture Arc Condition.|
|– While still holding SHIFT, if the cursor is moved to the imaginary ’90 degree window’ on the far side of the circle, the ARC CONDITION changes to MAXIMUM. Click to capture Arc Condition.|
Both methods yield the same end result. By using the ‘SHIFT’ method, the user can save a couple steps with each dimension.
Hope you find this useful. Until next time,
