Part I: SolidWorks Basics
Construction Geometry toggles between regular sketch entities and construction entities.
Construction sketch entities are not used to create solid or surface faces directly; they are only used
for reference —for example, revolve centerlines, extrude and pattern directions, and so forth. Be
careful with the icon for this function, because it looks almost identical to the No Solve Move icon,
especially as printed here in gray scale.
Note
The icons for Hide/Show Edges, No Solve Move, and Construction Geometry look substantially similar, and in
this black and white book, they may be indistinguishable. n
The Stretch sketch tool is intended for use in sketches where there are enough dimensions to make
a particular change difficult by changing dimensions only. It is similar in purpose and use to the
AutoCAD Stretch function because it was loosely modeled after the AutoCAD functionality. Stretch
enables you to specify a change that will change several dimensions simultaneously. Figure 3.18
shows the initial, intermediate, and final states of the sketch being stretched.
