Question

Some more GD&T questions

Hello all,

Thanks again for taking the time to read and possibly answer my questions.

How can we acquire the ASME standard for Creo 3.0, and maybe 4.0 versions? Currently, we have ANSI and ISO standards, but we use ASME for most assembly and part GD&T. What's the best way to get ahold of a license, standard file for ASME in Creo?

Second, we also use a lot of the fit tolerances (h7, H7 pin/hole size), but it isn't available for ANSI for our installation. Is that a separate file as well?

Last question, we also started noticing assembly files that we get from customers, their parts seem to have different units. We usually operate in Millimeters, but noticed some parts may have been set to inches or sometimes Centimeters. Is there a setting to set all parts/assembly files in the structure to one unit?

Hopefully this wasn't too much to ask, but thanks again reading. I'll be looking forward to any responses.

Thanks,

Jason

There are several places online you can buy ASME standards, including ASME website...The American Society of Mechanical Engineers

Y14.5 is the dimensioning and tolerancing book. Y14.100 is top level one that lists all the other related standards.

(The standard used to be ANSI and has since been renamed to ASME)

I'm not a fit tolerance guy so I can't answer that one.

You can convert the units once you bring them in but you would do them basically one at a time, there is no conversion setting.

file - prepare - model properties - units - change

First Question: You are going to have to be more specific. Creo supports ANSI, ISO and ASME but there are no files for them. For instance if you look at the drawing detail option gtol_datums the options are std_asme, std_ansi and std_iso among others.

Second question: If you are referring to hole sizes, those can be controlled with the .hol files. You can create those on your own. More info here:

Thanks Chris and Stephen for your quick replies.

With our Creo installation, we only have ANSI and ISO (std_iso, and std_asme), and that is all that is shown in Options list. Sorry for not being specific, but I'm looking for std_asme for Creo 3.

I think I found a request in another forum that basically tells me my answer. As far as using a Fit Tolerance, it's not yet supported for ASME standard, only ISO and DIN.

Thanks again,

Jason

There are multiple options in drawing setup for ASME/ISO/DIN/JIS for various purposes.

Are you just specifically looking for fit tolerance options? I don't understand exactly what you are asking.

Most of what you do to use a standard is to set your detail setup file to use <loadpoint>/text/iso.dtl, /jis.dtl, /prodetail.dtl for ASME, and to have your start/template files using the standard you like.  The standard templates assume ASME for inch models and ISO for mm models, but you can set it up as you like.

What ASME standard are you talking about? There are hundreds of them.
