discrepancies in UCS usage. User coordinate systems that were set individually
in AutoCAD will probably change if the viewports that use them were activated
in the AutoCAD LT session.
Work with AutoCAD for Mac 2D and 3D Solid Object Shading
In AutoCAD, visual styles provide shading and wireframe options for objects
in the current viewport. AutoCAD LT does not support visual styles. The
SHADEMODE command in AutoCAD LT provides only the 2D Wireframe and
Hidden options. You can use SHADEMODE in AutoCAD LT to turn off visual
styles in viewports that were created in AutoCAD. This exposes the underlying
geometry so you can easily edit drawings and use the geometry with precision
drawing tools such as object snaps.
WARNING Once you use the SHADEMODE command in AutoCAD LT to turn
solid object shading off for an object created in AutoCAD, you cannot turn it back
on except by using the UNDO command. If you make changes to the object, you
can turn the shading on again only in AutoCAD.
Work with Constraints
Some of the drawings that you work with will contain design requirements
enforced within the drawing itself through the use of constraints. Using
constraints, you can enforce requirements while experimenting with different
designs.
A constrained object will move in a predictable manner when edited or moved.
A single variable change can cause all related objects to change automatically,
enabling you to run through design iterations simply and effectively.
