Use this section of the Visibility form to change the visibility of key points.
Visibility - Key Points
Display Key Points
Switch this option on to enable square markers to be drawn around special points in the drawing. These options are often used to detect small gaps in the design which would be difficult to find otherwise.
For a complex drawing, these key points can be slow to determine, so their use could be detrimental to the viewing performance.
Choose one of:
- Show key points in all visible blocks - this could be slow in a complex drawing
- Show key points in the current block only - this option is likely to be quicker
The types of key points are:
Ends in space
These are entity start/end points which are neither joined, nor near to other points.
Near Ends
These are entity start/end points which are close to other points, but not joined.
Intersections
These are points where entities cross.
Joined Ends
These are entity start/end points which are coincident with other points.
For each of these types, you can specify a colour from Environment Options- Colours - Key points and a size in pixels for the markers.
Two tolerances define whether points are in space, near to each other or joined:
Space / Near Tolerance
If the distance between two points is greater than the tolerance, they are in space, otherwise they are near.
Near / Joined Tolerance
This value would normally be smaller than the Space/Near Tolerance. If the distance between two points is greater than this tolerance, they are near, otherwise they are joined.
