For a closed figure, this operation will open it. For an open figure, this operation will divide into two parts the geometry to which the vertex was added. Combine In ConceptDraw, figures can consist of multiple segments. Several segment, joined together are called geometry. A figure may have more than one geometry.
Combined objects take less space when saved.
If overlapping figures are combined, the overlapping areas become transparent. The main difference from the Combine operation resides in that if a solid outline results after the operation, it's considered as a single geometry. The Combine operation just groups figures with same properties, but never makes a new one out of them. That's why when a closed figure results after the Join operation, it's filled automatically, which never happens when the figures are combined. The Snap function is very helpful for this purpose.
