Shapes can be compound; in other words, shapes made up of more than one spline. You will use the 2D shapes to create 3D walls, a roof, interior trim, a bench, and a lamppost.
Two methods of wall creation are presented; extruding a floor plan (a view from above) to a height and extruding wall elevations (front view, side view, and so on with window and door openings) to a given thickness.
You will take advantage of the ability of your 3D application to use References, or clone objects. These are objects with a one way link back to the original. When you change the original, the Reference changes, but you can change the Reference (such as adding an Extrude modifier, for example) without having it pass the changes back up to the original.
The shapes in the right column of the Top view port are Reference clones of the originals in the left column. This process allows easy editing of the original 2D shapes in the left column, later in the exercise, to affect the 3D objects created by modifying the Reference clones.
If you คอนโด ราคาถูก are familiar with AutoCAD, you will be pleased to learn that when lofting or extruding, MAX handles compound shapes in a manner similar to ACAD's "normal" hatching mode.
For nested, non-overlapping splines in a single shape, 3D Studio MAX starts at the outer spline and creates a solid mesh to the next internal spline. From the first internal spline, MAX creates a void to the next internal spline and continues creating solid, void, solid, as deeply as the splines are nested.
We highly recommend you use this to your advantage by creating complex cross-section shapes with little system overhead, then lofting or extruding into the final 3D object. You can create compound shapes by using the Start New Shape check box when drawing 2D primitives or by collapsing shapes to an Editable Spline and using the Attach option to combine individual shapes into one.
