2. To resize the element in one dimension, position the pointer on the closest midpoint (so it displays as a bar). To resize the element in two dimensions at the same time, position the pointer on the closest corner (so it displays as an angle bracket).Note: If an element becomes erroneous during a stretch operation, such as overlapping boxes, the erroneous elements are highlighted (with “Xs) and they will not be part of the model until they are corrected.
