Center Marks
Center marks are annotations that mark circle or arc centers and describe
the geometry size on the drawing. With the Center
Mark tool, you can create a center mark or a center point on circular
edges. The center mark lines can be used as references for dimensioning.
Some items to note about center marks are as follows:
The axis of the circle or arc must be normal to
the drawing sheet.
Center marks are available as single marks, in
linear patterns, or in circular patterns. Linear patterns can include
connection lines. Circular patterns can include circular lines, radial
lines, and base center marks. Display attributes include mark size, extended
lines, and specifying the
for the center mark lines.
If you
dimension to a center mark, the extension lines are automatically shortened.
You can set an option so that center
marks are inserted automatically in new drawing views for holes, slots,
or fillets.
You can set options for center mark orientation
and location in Document
Properties - Centerlines / Center Marks.
Center marks propagate or insert automatically
into patterns if the pattern is created from a
and not a face or body.
You can rotate center marks individually, specifying
the rotation in degrees. In the
dialog box, you can choose to have center marks rotate automatically when
the view is rotated.
Center marks in Auxiliary Views are
oriented to the viewing direction such that one of the lines of the center
mark is parallel to the view arrow direction.
