58、 the RIGHT MOUSE BUTTONObject Alignment: Coordinate snappingUsing Co-ordinate alignment: Next to the co-ordinates of the geometry in the COG there are options to snap that co-ordinate to an existing point on an edge in the model. Co-ordinates can be: Start (xS,yS,zS) End (xE,yE,zE) Length (xL,yL,zL)

59、 Centre (xC,yC,zC) VertexTo Use: Click on the “Orange panel for a co-ordinate, and then with the mouse click on a point in the model. Icepak will then set that co-ordinate value to the position selected.Editing Objects: the Edit FormThe current objects edit form can be opened in the following waysDo
