In CATIA, a profile is defined as a combination of continuous lines and arcs.

Drawing continuous line means that the line automatically starts at the endpoint of the previous line.

You will notice that the expanded sketch tools toolbar has three buttons:

1. Line

2. Tangent Arc

3. Three Point Arc

While drawing a three arc starting with limits, you can specify the start and endpoint of the arc first and then the third point anywhere on it.

Drawing a Tangent Arc using the profile tool

After Draw the line, the Tangent Arc button becomes available.

An Arc is tangent to line which drawn earlier.

Note:

You will notice a constraint applied between the line and arc. This is the tangent constraint.

Drawing Three Point Arcs using the Profile Tool

The first point of the three point arc is the endpoint of the line you have drawn.
