Catia V5 I Multi section solid I coupling modes I Three Profiles I Explained in Detail

Hey Guys, Welcome to ''CAD TUTORIALS FOR BEGINNERS''
This Channel is specially started for beginners those who want to learn CAD Tools such as CATIA V5 , CREO PARAMETRIC, NX UNIGRAPHICS, SOLIDWORKS, AUTOCAD.
So,Here you will find all tutorials for CAD CAM software's.

Catia V5 I Multi section solid I coupling modes I Explained in Detail
Multisection solid with two profiles
Multisection solid with three profiles

multi section solid requirements:
1. no of segments on profile should be same.
2. closing points should lie within same quadrant
3. direction of flow of material should be same.

all guide paths must be connected to the profile
all guide path must be different entity

example:
1. two rectangles with different c/s without guide paths
2. 1rect and 1circle without guide paths
3. rectangle ad circle with guide paths
4. two circles with different c/s

guide paths are followed by material

coupling curves

ratio - vertices different/ c/s are different
tangency- all profiles are circular
vertices- vertices are same / c/s are same
