Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1

To begin with offset the class A and correct the patches.

Create CLASS B

Extract the surfaces from the class A using multiple extract and untrim them.

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.

]Trim the extra surfaces using trim command.Insert them into new geometrical set and name it with respective part names.

Apply fillets to the model after creating the entire 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 degree > preview.

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.
