Basic Profile Curves
Overview: There are several curve types available when creating a profile. The Basic Profile Creation unit exposes you to most commonly used curve types. In the next few topics you will be shown how to use these curve commands. Play the video for an overview of the basic curve options available. This file contains sound, so be sure to adjust your volume accordingly.
Lines
The Line icon is located on the Draw toolbar. This option creates a 'string' or 'chain' of lines. When you create your first line, you are prompted to select the start location of the line. When the location is selected, a rubber-band line is shown that stretches between the start point and the location of the cursor. You are then prompted to pick the end location for the line. Once you select the end of the line, a new rubber band stretches from the end of the first line to the cursor. You can continue to create lines to complete your profile.
Arcs
While creating lines, it may become necessary to create an arc. This can be done while still in the Line option by pressing 'A' on the keyboard. When 'A' is pressed, the rubber-band line turns into a rubber-band arc. The arc will be created either tangent to, or perpendicular to, the last curve drawn. The location of the cursor determines this. Moving the cursor around the last point selected, forces the arc to be drawn in the direction of cursor movement. To complete the arc, pick the location where you would like to end the arc. After an arc is created, the line command defaults back to creating lines. If a second arc is desired, press 'A' on the keyboard and another arc begins.
Circles
The most popular options are Circle by Center and Circle by Three Points. These options are located under the Circle fly-out on the Draw toolbar. To create a Circle by Center, simply pick the location of the circle center and pick the location to define the diameter. The Circle by Three Points uses three locations to define a circle.
