GLUE POINTS

Glue points are markers that are applied to objects in a drawing indicating positions on an object that should remain connected to other objects even when the original object is modified. Normally, when a line end is placed at the end of another line, IPAD is aware of the connection such that when one of the lines is modified the other line will also be modified to compensate for the first modification. Glue points allow you to mark any part of the line for such special consideration. So that if for example you wanted to connect three horizontal lines to one vertical line (a small distance apart), then you would place three glue points on the vertical line and place the end of each of the horizontal lines on one of the glue points. Any chanes to the vertical line will consequently be compensated for by changes in each of the horizontal lines.
