Week 9 - Attachment Feature Creation - Challenge 2
Week 9 - Attachment Feature Creation - Challenge 2
OBJECTIVE
- To create and Develop Class B and Class C surfaces along with proper Tooling axis from the Given Class A surface
- To create and Assemble of Dog House to the complete part body of Door Trim
- Draft analyse the both class A and completed part body of Door Trim

Tooling Axis
- Multi Faces or surfaces in the componenet.So,To Determine possible tooling direction.
- By Y direction Draft analysis is generated to the Door Trim Class A surface.
- Afterthat, Y direction is possible tooling axis is considered.
Draft Analysis of Class A Surface

Class B Creation
- From the Class A surfaces and offset to 2.5mm distance to Outward direction,Because component thickness is 2.5mm
- On the offset,somewhere of the surfaces is broken.
- So, reconstruct those surfaces by Multiextract where the area are broken
- then extrapolate and trim those surfaces and Edge fillets the surfaces.
- If fillet is inward minus the thickness value to the fillet value get from class A surface
- If fillet is outward adding the thickness to the fillet value

Class C creation
- From the Class A surface, selects boundary and sweep
- In sweep,With reference surface select boundary as a guided curve and ref.surface is Class A surface at 90 degree with distance of 5mm
- then some curving edges are inproper surface, so resolve those surface by using Multisolid surface command
- then extrapolate corner edges were not intersect to eachother and trim the excess edges
- After Using Join command join all the sweep surfaces is consider as a Class C surface

Final Component Creation
- Join the Class C surface to the Class A Surface
- And Trim Class B surface to the Join Of class c and A surfaces

Screenshot of Final Door Trim surface
- Change to Part body By using Closing Surface and Door handle solid component is completed
Dog House Creation
- Extract the surface,from where should be dog house to construct.
- Create Positioned sketch on the surface and draw a Rectangle and iso constraint
- Sweep the Sketched at 21mm distance at tooling axis direction with 1.5 degree
- Then offset the same Extract surface to 20 mm and trim to the sweep surface
- thicken the trim surface in part body is 2mm
- Draft angle is 1.5 degree at pulling direction of side core axis and neutral element is base of the Dog House
- then Edge fillet is 0.5mm inner surface and outer consider of thickness 2mm+0.5mm is 2.5mm
- then create "C" is where the doghouse contacts the backside of the surface
- then split to the dog house body
