Apparent Intersection Snap tool
The Apparent Intersection Snap tool snaps to the intersection of two entities
that do not intersect in three-dimensional space but seem to intersect in the
current view. You can snap to any two entities in the combination of an arc,
circle, line, infinite line, polyline, ray, ellipse, elliptical arc, spline,
hatch pattern, polygon mesh, or polyface mesh. You can also snap to an apparent
intersection point within a single entity, including a polyline or spline.
The Extended Apparent Intersection Snap option snaps to the logical location
where two entities (lines, arcs, or elliptical segments) would intersect if
they were of infinite length. progeCAD automatically uses the extension option
only when you type app in the command bar (not the full apparent
command name) after selecting a command, such as Line or Circle. Dashed extension
lines are drawn to help show the extended apparent intersection.
NOTE There are two types of intersection snaps. You can set
the Apparent Intersection Snap or Intersection Snap, but you cannot use both
at the same time.
To set the Apparent Intersection Snap
Do one of the following:
- Choose Settings > Entity Snap > Apparent Intersection Snap.
- On the Entity Snaps toolbar, click the Apparent Intersection Snap tool ().
- Type apparent and then press Enter.
To snap to an intersection, select the apparent intersection
To snap to an extended apparent intersection point
- Choose a command, for example, line.
- Type app and then press Enter.
- Select an extended apparent intersection point.
The Extended Apparent Intersection Snap turns off automatically after you
select a point.
