    Construction geometry panel Example of Construction geometry

    The illustration above shows the selections made in the dialog for construction geometry; the image to the right shows the virtual sharps are purple and edge extensions are green.

  • Centermarks - For automatic or manual centermarks, specify the default line color and thickness, mark size, gap size, and whether or not to extend the lines. For circular centermarks, specify whether to show a bolt circle, radial lines, and/or the pattern centermark.

    • To alter the length of the automatic or manual centermark lines, enable Extended lines. Hover over a centermark line to display the grip points at the end of each line. Click and drag one of the grip points outward or inward and drop at the new position. All lines move simultaneously. To move one line independently, hold Shift, and then drag and drop.

      Hovering over a line to expose grip points (shown in the first image above), click and dragging a grip point to extend all centermark lines outward (shown in the second image above), and holding Shift, then clicking and dragging the grip point to extend a single line upward (shown in the third image above)

    • When dragging the automatic or manual centermark grip point over an edge, a snap point is displayed as a red diamond, so you can drop the centermark extension lines at this snap point location (see the image below). Snap points are only displayed if all centermark extension lines are moved simultaneously. They are not displayed when Shift+dragging a grip point to move a single extension line.
