Week 9 - Challenge 3 - Bumper

1)

First we need to creat real tooling axis, for that we have to intersect the surface A in x and y axis then we got two dummy axis then we have to bisect the two lines in order to get the real tooling axis of surface .

1st we extract the bottom base because we can easily creat the tooling axis in z direction , then creat point on base surface and go for position sketch and select zx and zy plane for creating the dummy aixis

but in this complex model its very difficulty to vislble all parts in one axis. here we choose x axis because we can able to see more parts compare to other axis.

here, we set one point on appropriate edge for creating the tooling axis and creat line .

creat of b surface

1st we have to offset whole bumber at 3mm inside. and extract the non connectivity parts from main bumper.

trim both of it

creat of c surface

surface which has perpendicular to drafting axis then we have to go for drafting with tooling axis and gives 3 degree draft towards to outside

suppose surface which has parrallel to drafting axis then we go for reference with surface option and gives 90 degree for sweeep.

join A and C surface

finally trim the class B with join A and C surface

make it closed solid surface using closed surface

checking with drafting analysis

ensure the model should be 3 degree
