A new fi le opens in Inventor. The differences between a standard part and a
sheet metal part are subtle but important. Behind the scenes in a sheet metal
part, Inventor creates a number of named values that control the thickness of

radius of the bend. The sheet metal part also presents a different set of tools;
they will be offered on the Sheet Metal tab when you're fi nished sketching.
For learning purposes, you aren't going to draw your fi rst sketch as well as

7. A message at lower left in the status bar prompts you to “Select start
of line, drag off endpoint for tangent arc”. Inventor is asking you to
pick a place to start your line. Near lower right in the design window,
click and release the mouse button to start the Line tool.
8. Drag your cursor to the left. As you do so, Inventor displays a glyph of
a horizontal line when your line is horizontal, as shown in Figure 2.2.

9. When your line looks similar to Figure 2.2 and is horizontal, click
again to create the fi rst segment.
When you create a line segment that has a glyph showing whether
it's vertical, horizontal, perpendicular, or parallel to another object,
