Elements of your drawing may be modified using the icons on the lower left side.
The first icon is used to combine objects into groups that can be operated on as a whole. For example, if you have a row of boxes, you can weld them into a group by these steps:
Click on the grouping icon (under
).
“Handles” (little boxes)
will appear on the screen for each object.
Tag the objects you want to group: left-click on the handle of each you want to group.
You can also tag all the objects in an area by this procedure: center-click above the upper left corner of the items; then drag the mouse to a position below and to the right of the items, and center-click again.
Once you have tagged the items in your group (and their handles have turned solid), right-click to form the group.
You can now move and copy the group as a single item.
To break a group back into its component objects, use
the “break compound” icon.
To move an object or group:
If you want to move the object either straight up, straight down, straight left, or straight right, substitute a center-click for the left-click in the step 2 above.
Copying is just like moving, except that after step 4 there will
be a completely new object at the new position, and the old object
will still be there.
