Drawing Arc and Profile

Drawing Arcs


Drawing Arcs by defining the center point



Menu:  Insert  >  Profile  >  Circle  >  Arc
Toolbar:  profile  >  Circle  >  Arc


Drawing three point Arcs


Menu:  Insert  >  Profile  >  Circle  >  Three point Arc
Toolbar:  Profile  >  Circle  >  Three point Arc


Drawing Three Point Arcs Starting with limits


Menu:  Insert  >  Profile  >  Circle  >  Three Point Arc starting with Limits
Toolbar:  Profile  >  Circle  >  Three Point arc starting with limits





Drawing Profiles




Menu:  Insert  >  Profile  >  Profile
Toolbar:  Profile  >  Profile


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.

Drawing a Three Point Circle

Drawing Circles using Coordinates


Menu:  Insert  >  Profile  >  Circle  >  Circle using coordinates
Toolbar:  Profile  >  Circle  >  Circle using coordinates


Circles can also be drawn by specifying the absolute coordinates values of the center and radius.




Drawing Tri-Tangent Circles


Menu:  Insert  >  Profile  >  Circle  >Tri- Tangent Circle
Toolbar:  Profile  >  Circle  >Tri-Tangent Circle
To draw it, you first need to draw the three elements, which can be lines, circles, ellipse, arcs, or any geometrical element, to which a circle can form a tangent relation.
