Door Arm Rest Week 8 Challenge

AIM:

To create a tooling axis and extract B-surface and C surface from the given Class-A surface. To perform draft analysis on a solid body created by the Class-A surface.

PROCEDURE:

Firstly, open the model using the open command.

Create a point and insert a local axis system on it.

Create a line on the YZ surface by projecting the class-A surface on the sketch.

Similarly, create a line on the ZX surface by projecting the intersected class-A surface.

Now, create a bisect line using YZ and ZX lines and rename it as Horizontal Tooling axis.

Similarly, create a vertical tooling axis for the pocket.

To create B surface, extract the class-A surfaces, untrim and extrapolate it.

The surface is stepping down with a minimum value.

Extract and offset the surface separately.

Join them by creating a profile and extracting a guide curve using sweep option.

After extrapolating, trim the wall attached surfaces.

Now, offset the surfaces at a value of 2.5mm below.

After offsetting the surface trim the B-surface.

Then give the edge fillet to it.

Now the Class-B surface is created.

To create a Class-C surface, use the multi extract command and extract the boundaries.

Then use the sweep command to create a surface by selecting the profile as boundary and guide as horizontal & vertical tooling axis and trim it.

After all the surfaces are created join the Class-A and Class-C surfaces.

Now, trim it with Class-B surface and check for the boundaries.

Now, create a part body and select a closed solid.

Draft Analysis is done on the solid body.

Horizontal draft analysis for side arm rest.

Vertical draft analysis for pocket.

RESULT:

The Class B & C surfaces have been created using tooling axis and drafting analysis is done on the solid body created by A, B and C surfaces.
