Week 10 - Challenge 2- Attachment Feature Creation (Dog House)

Given A-Surface

Tooling Axis Creation

To create Tooling Axis we took center of the circle to create a line from the bulging on the surface.

B-Surface Creation

To Create B-Surface :

• As per the given thickness, the A-surface was Offseted in the direction of tooling axis using offset command.
• If there was still some pathes left out , it was rectified by using multiple extract, splines and fill commands.

C-Surface Creation

To create a C-Surface:

• Use of boundary command to extarct the boundary curves from A-surface to sweep in the parallel or perpendicular direction of tooling axis incluidng the draft angle (3 degrees ), if possible .
• If not possible anywhere, we tried to make out c-surface using multiple extarct and spilne command.

A-C Surface creation

When the C-Surface was created , we joined the A and C Surface using the join command.

Close Surface Creation

Once A-C Surafce is created the B-Surface needs to get trimmed off using trim command to get Close -surface.

Draft Analysis on Close Surface .

Convert the Close surface into part body using close surface command in part modelling module.

Then Dog House was Designed as per the tutorial video guidelines at specified points.
