Information such as Selection, Alt+selection, move anchoring, axis, and ruler dimension is all stored with the group. You create a group from any set of selected objects. You can save the ruler dimensions as Groups Sets of objects that appear in the Groups tab. Measurements to your design, drawing sheet, or 3D markup. In SpaceClaim, if you do want to save a dimension with your design, use the Ruler Dimension Annotation on a drawing showing measurement of an edge or face. Rather, they are tools for precise control during the creation or modification of a design.
In SpaceClaim, dimensions are not constraints. You can dimension every element in your design, from lines in sketches to faces of solids.
