Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1
AIM:
To Create the Door Handle 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 Attach B side Features in the component.
To perform the Draft analysis on the model.
CREATING TOOLING AXIS -
The Tooling Direction is basically the direction that the mold pulls a part. The
mold is built in two separate pieces, basically. You have a Cavity side and you have the
Core side. The Core pulls apart from the Cavity and that's the Dye line or the Tooling
Select the face which is covering all faces of class A surface and using multi extract command extract the flat surface
and draw the normal to surface line and check it . this is the tooling axis of door handle.
DRAFT ANALYSIS FOR CLASS A SURFACE
The Draft Analysis command enables you to detect if the part you drafted will be
easily removed. This type of analysis is performed based on color ranges identifying zones
on the analyzed element where the deviation from the draft direction at any point,
corresponds to specified values.
Before going to drat analysis go to customized view parameter >under mesh >check
material and then click ok.
Now for draft analyses go to insert » analysis » feature draft analysis.
Use the compasss to define the draft direction.
In the colour scale change the draft angle to 3 degree.
The component changes to green in indication of passing draft angle.
Use running point to check the angle on the component

DRAFT ANALYSIS FOR SOLID PART

CREATING CLASS B SURFACE
Extract the surfaces from the class A using multiple extract ,
Use Extrapolate to make sure that all the untrims are properly intersected to trim and offset
the surfaces to 2.5 mm to create the thickness
Insert them into new geometrical set and name it with respective parts
extraolate the edges of b surface 12mm.
make sure that there is only one boundry and published the b surface.

CREATING CLASS C SURFACE
Extract the boundary from the class A surface using boundary command.
Using disassemble tool to divide the boundary as the boundary contains domains.
Use sweep command > choose profile type line > subtype as with draft direction > choose
guide curve and draft direction > draft angle as 3 deg
after done the sweep operation jion the class a surface using jion command

After getting class A+C jion then trim the output with class B surface to get final output.

Now open part design workbench and using close body surface create a solid of the
component
