Draft Command - Or Similar

[BrittToolEngineer]

Greetings:

File attached of the rectangle part that I am designing. I am attempting to put a 78° angle on the (2) long edges of the part and a 71° angle on the short edges of the part and blend those at the corner. Also, the height of the vertical wall left after the draft is .032. Can anyone help me learn to install this?

Thanks,

Brent

Blends are a little funky, but check it out:

The attached file cleans up the blends, but adds some complexity. Only 1 corner is done to show the technique.

A little variation on the cowski model.

Here is another thought, I think I may have the draft angles wrong, This is in a NX1880 If you need I can attach an earlier version. The Basic Idea is to create A coordinate system .032 up in the "Z" direction of current coordinate system. Create two Datum planes at your draft angles. Then use replace face to replace the faces with the datum planes. This way you can keep your blend. Once I got one side done I just mirrored the body to get the lengths, unite and then extrude your .032 down. I thought Extruding with a multiple draft would work but getting the fillets on the end was a bit difficult. I guess this fillet is what drives what all of this could look like. Just a quick thought.

I updated the blends in my model using an approach almost identical to cowski's, looks pretty good. Unfortunately, I'm using NX11 and can't open SDETER's and multicadusers's versions, would like to see them.

Basically, the model was split at the datum plane cowski created, then each half was drafted separately, then both halves united. The blends were left on as is so the edges would match and would then be tapered blends instead of constant. This type of modification is required quite a bit for customers who don't know how to model injection molded parts.

Here is a NX 11 Version. Like I mention I do not know if my angles are correct. To Fix the angles to what you need just change the datum plane angles, Hopefully it will update well.

I think this might be the simplest method in this specific case. - i.e there is no other geometry that prevents me from going this way.
1, move the bottom face upwards .032
2, apply draft ( 90-78 on the long sides and 90-71 on the short, i assume this is correct ?)
3, drag/extrude bottom downwards .032
This is a NX10 file.
you did not specify the draft in the corners, i let NX handle that ,- i do not know either , i did not check.
