Week 10 - Challenge 2- Attachment Feature Creation (Dog House)
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 in that a plane is created with reference of surface.
- The intersection of the Class A surface is taken on that plane and from that a two lines are formed which is the referance lines for Tooling Axis.
- Then by bisecting the two reference lines we get the 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.
DOG HOUSE DESIGN:
- The base surface is extracted and a plane is created through the surface.
- Dog house sketch is drawn and extruded.
- The base is then offsetted at the top of extrude to close the top.
- Then thicksurface is used to make it solid.
- It is then drafted and filletted through the axis created for doghouse.
- Finally, the Dog House is assembled with the Door Trim.
- Another Dog House is created using translation method.
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.
DOG HOUSE DRAFT ANALYSIS:
- A line is created through Dog House plane which is Dog House Tooling Axis.
- Which is also checked using Draft Analysis.
