Automotive seating design in Catia v5:

Project 1:

The Cad provided is a IGS file without any history. It is front row back foam. Use Under build / Over build technology. Make use of the foam terminology. Make foam parametric and use standards for making the parts.

1 – The Complete design should be parametric.

2 – Use Best Practices as Explained.

3 – Use of best practice and maximum use part design.

2 – Use Best Practices as Explained.

Estimated Hours to complete the Part : 9 hours

Making of seat back:

In this case we've got provided with dump solid of seat back and head rest so we'll have to creatte sto then we'll have to create the solid foam so for that i extracted the surfaces of the dump solid and repair some dameges over the surfaces then i've created sto

And now we've got a proper sto with no gaps

Creating H-point:

To create the H-point i've created point over the curve then i've created lines from that point in 40 mm length and 20 mm height

Then i created another point over edge of the line and i created with plane as well so that's our H-point

From that i created line and created planes and points as well

Then i created intersections of back surface while am i sketching i created projection of the intersection then i offsetted down wards 5mm then same thing i did with the all other planes

After that i created multisection surface for the back side

Making of wings:

So in this case i've followed a different type of approach which contrast to other apporach which shown in video, So, what am i done is I've extracted the surfaces of wings

Offseted the top surfaces up ward 2mm and offseted the side surfaces in wards 2mm

Then i untrimmed and extrapolated those surfaces

then I trimmed them together and we've got a proper wings then i've done the same thing for the another wings as well

Then i trimmed them together

Then i begin to create the top and bottom surfaces first i extracted the top surface then took a boundry and extrapolated then i trimmed them together and the same thing I've done for the bottom surface as well.

After that i've extracted the rest (bottom) surface then untrimmed it and extrapolated it then trimmed with together

So, eventually we've got a complete surface body of the foam

Then i created the soild foam

Making of seat lower part:

Then whatever methods i followed for create seat upper part same thing i applied for the seat lower part as well

STO:

Surface body:

Solid foam:

Making a solid foam from Unproper sto:

Given data:

Then i've begin with work on those surfaces to make proper sto

Then i created proper seat trim outline

And the same procedure we followed for the seat upper and lower applied on this part as well but i tried another different approach in this case as well

As we seen before i took intersections between sto and planes which i created and then i created the sketch and offseted the line of cushion surface by 5mm

After that i created multisection surface with those lines

And to be specific i approached in a different manner for side surface what that is i've extracted those lines from intersections

then i create surface and untrimmed it then offseted itself inside by 2mm and same thing i've done for the other side as well

Same thing i've done for the upper sides of my polsters but in this case i've offseted those surfaces by 2 mm upwards and same thing i've done for the other side as well
