I have tried the solutions I found here (zero) and have not been able to get past such a simple part.
I cannot seem to get INV to miter my flange corners where they overlap..
Any help would be great.
attached is part I am working o
Thanks in advbance
Solved! Go to Solution.
It looks like you are doing too much work, but it isn't at all clear to me what you want your final geometry to look like?
Can you use the standard tools to model the geometry so that someone can them demonstrate with the sheet metal tools.
I noticed your first sketch wasn't constrained?
Is something like attached what you are after?
Once I know exactly what you are after I might be able to simplify it a bit more.
The two attachments you replied with are pretty much what I am trying to achieve. The final flanges in my attachment are to be of the same length/distance and NOT overlapping as they were. I see you made the miter cut at 45 degrees and that is what I want to do as this will be the male insert in a male/female assembly.

I could probably put the information from Sketch3 into Sketch1 and cut from-to to simplify just a bit.
Haha, thanks! THat was the last thing I read before beginning these parts and did follow the settings and steps. I did anchor this, is that part of the problem?
I read last week about the BORN Technique but an not fully sure I comprehend it. I am to believe that setting my drawing/model to the origin point will giove me more control and etc...
So I am under the impression that when I begin my next sketch I should anchor/constrain the center of my base, or however I want the prepresentation to be set of my model to the 0, 0, 0 point of origin the connects the three axis planes. I think that is what it means.
I haven't constrained this part to the origin, is that my problem? I will give it a try and see how I do.
Thanks for all the pointers and help.
I haven't constrained this part to the origin, is that my problem?
You should pick a logical location on your part to constrain to the origin.
This isn't required - but helps in editing (who does everything correct the first time with no editing).
If you have a part with symmetry - put the origin in the center of that symmetry - this keeps you from having to create extra workplanes or other geometry. Reduce work by mirror features or other tricks (be lazy in a good way).
The BORN technique refers to using the origin workplanes (rather than part faces) for sketches as much as is practical.
(Note I say as much as practical - some companies have you go beyond practical and have nearly everything if not everything tied to the origin planes. The reason for this is more robust parts. Geometry built on top of geometry is more likely to fail if the underlying geometry is changed too much. The origin workplanes can't be deleted.)
Sheet metal presents a special case exception to the general rule where some features must be created on part faces rather than workplanes (punches, cut with cut across bend, project flat pattern in sketch...).
Some people think constraining sketches is more work. I have not seen any evidence of this. All my evidence indicates that it is actually much faster as Inventor does most of the constraining for you once you learn how it works. All my evidence indicates the the best quality work and the fastest work comes from users who constrain everything. (of course there are exceptions to everything - but these pros know those exceptions.
Now that I have a better understanding of what the BORN techniques are, I realize that i commonly use them as per stated your benefits and usability during assembly, which is where those techniques make a difference for me as a noob.
Okay, I reopened the part I submitted to this thread, constrained the part to the plane origin, but I still cannot seem to get auto miter option started, it is greyed out. Help! It would be easier to restart i think, but I gotta know how to not have this happen again, and would like to know what I did wrong. Maybe you explained it above?, but I didn't understand... I still do not know how to correct this as I have constrained to a plane. I returned to the flange that is too long (the one that makes it overlap hte oposite) and used the "To" option to edit it to to the same height/length as the opposite, but as I click "OK" I get the error saying that "flange body intersects with..."
"Edit Sheet Metal Flange: problems encountered while executing this command.
Helpmiter.ipt: Warnings occurred during update
Feature body intersects the existing part or self-intersects.
Flange Body intersects with the existing body or self-intersects.
Feature Compute Warning."
Here I sit and ponder this and how to get passed it. I have the "Miter/RipSeam Gap" located in the "Sheet Metal Rule" options of "Sheet Metal Defaulsts" set to "Thickness" (which I corrected as .0245 for the sheet I am using) but still, no auto-help, just more auto-frustration... This piece of "sheet" is starting to piss me off, lol.
I prolly could go back and cut the corners myself, but isn't the point of the afore mentioned option to eliminate those actions in said situations?
Thanks for all your help
Will Inventor not do the 45 degree corners that need be there automatically?
hopefully not becaust I do not know how to do that. If I cannot figure this out I will have to sketch the 45 degree corners instead of removing them because the next problem I have is figuring out how to remove portions, as to remove 50% of a square, cut frpm corner to opposite coner. I could use some help there to ..
Thanks for taking the time,
