Hole Features
A hole feature is a parametric drilled,counterbored, countersunk or threaded hole. SeeFigure 3-1 and 3-2. The hole feature is createdwith the HOLE command and assigned propertiessuch as diameter, depth, thread type andtermination methods.
Once a hole feature has been created in the part,it can be copied or arrayed in rectangular orcircular pattern. The copied or arrayed holes onlyrepresent the original feature and if it is revised, allthe holes that were copied or arrayed from it willautomatically update.
Holes are created and located onto the sketcheither in a specified location or onto a centerpoint inserted and constrained on the sketch. You specify the hole on a preview image inthe Hole dialogue box.
Center Points
The CENTER POINT command is used tocreate center points on a model. Centerpoints locate the center of hole(s) that areautomatically found by the HOLE command.

When inserting a hole(s) on the part, use the HOLE command to do it rather thencreating the holes using geometry as you have been doing up this point in themodules. They are easier to create and edit in the future.

Step 6 Start a new sketch on the top plane. Enter the CENTER POINT command and place acenter approximately in the center of the model. (Figure Step 6A and 6B)
Author's Comments: To speed up the modeling process, the location of the center point can beapproximated and then located exactly with dimensions.
Step 7 Place two dimensions from the edges to the center point to constrain it onto the sketch. Finish the sketch. (Figure Step 7)

The Key Principles in Module 3
1 When inserting holes on the part, use the HOLE command to do it rather then creating the holesusing geometry as you have been doing up this point in the modules. They are easier to createand edit. 2 Insert center points to locate the center of holes rather then using geometry to locate thecenters. This method is much faster and easier. 3 To speed up the modeling process, the location of the center point can be approximated andthen located exactly with dimensions.

Loft Features
A loft feature, created with the LOFT command, is a blend or transitionsolid that connects two or more planer sections or part faces that usuallyhave different shapes. The planer sections also called profiles. Forexample, you can create a solid that connects a circular and arectangular shape as shown in Figure 13-1.
The LOFT command can create complex shapes like the ones used incommercial products. A good example of this would be a cellular phone. In this module, you will be learning how to create simple lofts.
There is no limit to the number of sections that can be lofted in a singlecommand.
