limits and fits or tolerances

david_knight

I have looked at site and find no clear indication on limits and fits.
Can not issue a drawing without minimum and maximum sizes for critical dimensions and angles but do not see how to apply them in part studio or drawing.
Do not see geometric tolerances either.
Any thoughts on this hope I have not missed the obvious stuff

Ok got it this time. Add dimension. End dimensioning function. Click on dimension and edit tolerance.
This is good for me no problems.
Did not find this in help text.
Many thanks for big clue Andrew.

You're welcome.

Bonus clue (for being a 'good sport'): try downloading "Help" as a pdf

https://cad.onshape.com/help/PDF/Onshape.pdf

This lets you search the entire Help file without having to laboriously expand every heading on the pages where there are hits (the topics are pre-expanded, in the pdf version)

Further advantage is that the table of contents and index both link straight to the topics.
[However I notice the word "tolerance" does not appear in either (yet), but a "search" of the pdf does bring it straight up.]

Sorry, no tolerances yet in models, only in drawings
And no GDT yet, nor automation of ISO shaft/hole limits and fits.

david_knight

OK thanks but where in drawings, I do not see it. Do you mean in text entry field.
This is serious issue for design drawings bring to top of Agile to do list please.
Can do clash analysis in my head in models.
But critical in drawn communications to others.

Is there possible to mark standard ISO fit  to dimension? Like 20 H7 and deviation dimensions inside of parenthesis.

NeilCooke

@jari_viitala531 there are no built-in tables for limits and fits, but it is possible to manually construct the data you need. Please create an improvement request in the category on the right --->

Does anyone know if there is an IR for this?

@paul_charlton Does this help for now? also vote it up.

paul_charlton

@NeilCooke Typing in manually is ok when you have a couple to do. We have a need for this now and are getting hammered by our largest client who is a solid works user. To have to type in "g6" then look up the relevant tolerances and type them in is too slow and also has lots of scope for error.

Please provide a solution as soon as possible.

Did anybody vote for this? It’s the only way to make things happen...

Thanks @NeilCooke for pointing us to the IR

paul_charlton

Has anything happened with this.
About to start another major project and tolerancing now is at glacial speeds not to mention mind numbing.

jurjen_vellinga

Has anything happened? Not being able to fill a nominal tolerance is a deal breaker for me.

daniel_hallberg620

This is a big problem, we need a faster way to do this. Typing all tolerances by hand is terrible.

There was a big update in November which included this:

What's New 1.173 - Fit Class Tolerances

PeteYodis

We are also working on additional drawing tolerance tools to support non hole case as well as hole override support (important for references to a version where these were not defined for hole features).  The What's new that @S1mon posted above was really round 1 of the feature set.
