Week 10 - Challenge 3 - Door Trim Lower with Engineering Features

AIM: The objective of this project is

To create the Door Trim closed component from the given Class-A surface.
To create the tooling axis for the given Class-A Surface meeting the requirements of the draft angle.
To create Engineering Features ( HEAT STACK & FOUR WAY LOCATOR) on the B side surface considering the design rules for that.
To perform the Draft analysis on the Final component.

STEP 1

CLASS A SURFACE

STEP 2

TOOLING AXIS

Create a point on the class A surface and create a line with reference to that point and the respective direction on the compass.

STEP 3

DRAFT ANALYSIS ON CLASS A SURFACE

Use Feature Draft Analysis on the class A surface by aligning the compass to the tooling axis and select the A surface as the element and then click Ok.

STEP 4

CLASS B SURFACE

Use offset feature to offset the class A surface of about 2.5 mm.
Use Extract and Multiple Surface Section to repair the gaps on the class B surface.
Otherwise, use Blend feature if Multi surface sectioin is not coming correct. After repairing the Class B surface , extrapolate the surface by using Extrapolate feature.

STEP 5

CLASS C SURFACE

Create a boundary on the Class A Surface using Boundary feature or Curve smooth feature. And then use Sweep option to the boundary to create a sweep surface with an required draft angle. If the sweep came properly without any twist and turns or any sharp edges, then its fine. Otherwise we need to sweep seperately from the class A surface using sweep and multiple surface section.
After doing that, join all the sweeped surfaces using Join feature.

STEP 6

CLOSED SURFACE

First, join the Class A Surface with Sweeped Class C Surface by uising Join Feature. Then, use Trim feature to trim the joined surfaces with the class B surface.Thus the closed surface is completed.

STEP 7

B SIDE FEATURE CREATION

HEAT STACK CREATION

First, create a reference plane on the B surface and draw the profile for heat stack.
Use Pad option on part design to the sktech and pad it ti the height of about 20 mm.
Now, use draft on the padded surface with an draft angle of about 0.5 degree.
Then, draw a cross section lines of about 15 mm each for making the ribs for heat stack.
Again use Pad to the sketch and use draft on it.

FOUR WAY LOCATOR

Create a cross secting line of about 15 mmm each and symmetry it to the axis.
Use Pad to the sketch of height 20 mm. And use draft on it with an angle of about 0.5 degree.

Finally, add all the engineering features to the solid component and use draft analysis to the final component.
