 * Linear dimensions: hold the key, or click on the  button, and pick a straight edge, then pick a second point to draw the dimension line parallel to that edge.
 * you can also pre-select the edge before calling the tool.


 * Horizontal and vertical dimensions: pick one point, then pick a second point, then hold the key and move the pointer horizontally or vertically, then pick a third point to draw the dimension line parallel to either the X axis or the Y axis.
 * click and hold and move the pointer in different directions many times until the dimension line aligns to the desired axis. Clicking  while the pointer is far from the first point will usually align the dimension to the X axis; if the pointer is close to the first point it will usually align the dimension to the Y axis.
 * instead of picking two points, pick an edge while holding.


 * Diameter dimensions: hold the key and pick a curved edge, then pick a second point to draw the dimension line.
 * Radius dimensions: hold the key and pick a curved edge, then hold the  key and pick a second point to draw the dimension line.
 * Angular dimensions: hold the key and then pick two straight edges, then pick a point between the two edges to show the acute or obtuse angle, or elsewhere to show a supplementary or explementary angle.
 * the displayed angle largely depends on the original position of the selected edges. If you would like to display a particular angle, you may have to add auxiliary Draft Lines that extend from the original edges, and measure these extensions.
