Return Flange Issue 3

[johnnyblr]

Greetings,

Find attached a simple NX model of a cube with two sketches that I created to extrude tools and remove material fromt the cube. At their intersection, I want to create a flange. I've extruded the intersect to create a sheet and then thickened. When I try to unite with the main block, I get an error message due to a very small mismatch between the main block and the thickened flange. I'm not sure why. Any advice? I don't have any sheet metal packages with the NX 7.5 system I am using.

In the Unite operation, change the "tolerance" to equal 1.

They will unite......then delete the smaller, funny looking flange face to clean up the model.

[green]To the Toolmaker, your nice little cartoon drawing of your glass looks cool, but your solid model sucks. Do you want me to fix it, or are you going to take all week to get it back to me so I can get some work done?[/green]

Capnhook - Thanks for checking into this, but there is still a problem. When I put a fillet in, there are mismatches at the center of block. I'll keep trying as well.

If you offset the bottom face of the flange into the block it will then unite. If you inspect the flange carefully, you will notice that the back face of the thicken is not the same as the back face of the block (a replace face can remedy this) nor is the top face of the flange a perfect offset of the top face of the block. This can be seen in my "optionA" file.

I tend to avoid thicken features where possible, the "optionB" file shows an alternative construction.

Yep, cowski's go it. Can't get away with not offsetting that face first.

All,

Thanks for the help and great input! I was able to solve my modeling issue using the tips from eex23 and cowski option B.

Have a great day!!

One last option which I think is easier still. Have a look and see what you think. All done with the power of extrude ;-)

Cheers
