Week 8 - Challenge 5 - Door Trim Lower

Aim :

• To Create the Door Trim Plastic component through the given Class-A surface.
• Begin with the tooling axis for the given Class-A Surface.
• Created Tooling axis should clear the draft analysis of class a surface and final solid body.

Take the Thickness of the component to be 2.5 mm.

Given Class-A Surface :-

Determine Tooling Axis:

• Create a Tooling Axis along the best possible direction as per the Class A.
• In this model NORMAL TO SURFACE method is used for creating tooling axis.
• After creation of tooling axis publish the tooling Axis.

DRAFT ANALYSIS OF CLASS A SURFACE:

Change View Mode Customization to Material mode

Go to INSERT > ANALYSIS > FEATURE DRAFT ANALYSIS and move the compass to the Tooling Axis. Change the range to 3°. Apply the settings.

Uses the compass to define the new current draft direction.

Class B surface :

we offset the Class A surface and get the B surface body here we offset the 2.5mm value so we get the thickness is 2.5mm is mention in above so we offset the A surface for 2.5mm .

After the offset we get the surface but in that offset some patches of surface is missing so we required to solve it.

Class C Surface:

To create a Class C surface, first, extract the boundaries of the Class A Surface.

Now using the Sweep option create the surface. To perform this operation, Go to the Toolbar > Sweep > Profile type > Line > Subtype: With draft direction > Guide curve 1- (select the extracted boundaries) the in Draft direction (select the tooling axis) angle and length as 3° and 4mm respectively and click ok.

Conclusion

I have successfully created the class-B and Class-C surfaces of DOOR TRIM using the given Class-A surface along with the tooling axis in the CATIA surface workbench.
