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

TOOLING AXIS:

• A geometrical set for Tooling Axis is created and base is extracted as referance surface.
• A point in created at the surface and y axis is taken as reference axis.
• Then a line is drawn through the point which is our Tooling Axis.

CLASS B SURFACE:

• Since we have different number of fillets, the offset method is the easy way for the B surface.
• The A surface is offsetted for 2.5mm and there will be discontinuity along the surface.
• They are repaired by using Fill, Multi-section and Join commands.

CLASS C SURFACE:

• Mutiple extract is used to form the boundary along the A surface.
• Then the boundary was made into surface by using sweep with respect to draft direction of the Tooling Axis.
• The swept surfaces were extrapolated and trimmed to form Class C surface.

FINAL TRIM:

• At the final trim part, the A surface and C surface are joined together.
• The surface we get above is them trimmed with the B surface to form the Door Trim surface.
• Then at part design, the hollow part is converted into a solid Door Trim by using closed surface command.

LOCATORS:

• The reference plane is taken is required area and sketch is drawn.
• It is padded using thick component with certain value and then drafted, chamfered and filleted.
• Another Locator is created using translation method.

HEAT STAKES:

• The reference points are given, required sketch is drawn.
• Which is padded and drafted to a certain value.
• A rib for the Heat Stakes is created in sketch and padded.
• The rib is then trimmed with the Heat Stakes solid.
• Like that, 16 Heat Stakes are created by translation using reference points.

MAIN ASSY:

• A main body is created, so the all the sub bodies will be assembled together.
• At first, the Door Trim is assembled in the main body.
• The Locators are trimmed with the main body.
• All the Heat Stakes are assembled in a single body and then trimmed to the main body.

DRAFT ANALYSIS:

• In Draft Analysis tool bar, use the compass and drag it to set along the Tooling Axis of the surface.
• By clicking the surface, it will turn into green colour. if it is blue, the analysis was inversely done which is corrected just by flipping the direction.
• Draft Analysis on the solid part is in green and red regions.
• Individual Draft Analysis is done for both solid and surface.
