Selecting Dimension Points

You can select a line or a point as the dimensioned element. Just like when adding basic geometry elements or building components, the appearance of the cursor indicates whether you are selecting a point on a line, a start or end point of a line, an intersection point of lines, the center of a circle/arc, or a quarter point of a circle/arc. For example, a start/end point of a line:

Selecting a center point of a line is the exception. During dimensioning, the appearance of the cursor will not change when you move the cursor near the center point of a line. You can select a center point of a line as the point to be dimensioned as follows:

1. Move the cursor near the line.
2. Press the C key.
