chamfering or beveling a part from a sketch

[rclement]

Gentleman

im trying to create this piece in inventor from autocad

and im having a hard time trying to do it. I would like to bevel that

triangular section to a 9 degree plane and then extrude cut the top

sketch thru. I am posting my model that I have semi accomplished along with the autocad drawing.

I would appreciate any help I can get. Maybe it has a simple solution I don't see.

or a more complex one. Either way its kicking my butt.

wont let me load ipt file?

[JDMather]

Zip the file first.

[rclement]

Why cant upload ipt files? anyway here's the zip file. ty

[JDMather]

That file is not a *.zip file, it is a *.rar file.

I have only Windows OS on my clean Inventor machine, no extraneous software installed.

Hi Bob,

Here is a makeshift of your part. I didn't follow your dimensions but the overall shape looks the same to me.

To the rest of the Inventor users (who read this post) - is there a change in naming convention for the bolts I am unaware of? What is Hex Head Cap Screw?

Best Regards,

Igor.

@IgorMir A bolt is a bolt, and a cap screw is a cap screw, and in general practice, they are pretty much indistinguishable, in my experience.  But there are different standards for each, at least in the US (ANSI standards), and I assume the same is true for DIN & ISO.

If I recall correctly, a bolt is used with a nut; a cap screw is used in other internally threaded holes.  I don't know why there are different standards, but I suppose there's a valid historical reason.

Here's your part as best I can understand the drawing.  The drawing is somewhat over-dimensioned, so I can't always tell what the driving dimensions are, but this is one way to tackle the problem.

I mirrored the right hand part to create the left hand part, which is my usual practice with mirrored parts, then deriving them into individual parts for assembly and detailing.

Edit: attached file is Inventor 2020 format.  I created a workplane and used it to trim the part to create the problem bevel.

ty I get the split tool but getting that .032 dim is driving me crazy.

[rclement]

thank you for your help. that .032 din gets me

Hi Sam;

Thanks for looking into it, much appreciated.

Yes, there is a term exist - Hex Head Cap Screw. I Googled it afterwards. (Should do it other way around, of course 🙂 )

Upon further investigation it appears that when dealing with Hole tool - there is no spec under ISO standard for the Counterbore hole for the HHB. Only for HHCS. ANSI metric gives such an option.

In the assembly files selecting of HHCS is only available in ANSI standard. ISO one doesn't give such an option.

Yet two different instances of the fittings while absolutely identical in appearance - offer different description in iProperties. Besides - HHCS and HHB do have the hex head of 16mm. Only DIN standard delivers 17mm head. And in GOST one - for some standards you can select a head with 16 or 17 mm.  To cut the long story short - here is an assembly with the fittings for anyone, who wants to have a look at it.

The point of the post is to make some users, who are not yet versatile in things mechanical, aware of such differences. Inadvertently there might be a case when specified contrebore hole for the HHB will not accomodated the corresponding socket head spanner.

Cheers,

Igor.

Hi Bob;

Here is your original part. I have just cleaned it up. Have a look at the length of the browser in my part and yours. It should give you some idea on amount of entries required to model the part.

Cheers,

Igor.
