ISO fit marking to dimension

JJViJJVi Member Posts: 3 EDU
edited September 2017 in Product Feedback
Currently dimensioning tool is not suitable for standard ISO fit marking. Marking can be made as described in picture a, but major drawback is, that dimensions does not follow geometry changes. Also there is no possiblity to use standard deviation dimensions, picture b), because OS added dimension "automaticly"...even it has taken away. Also standard tolerance fitting values would be great.

    @paul_charlton is this the style of fit and tolerancing dimensioning you need?

    I envision a pull down left of the automatically generated dimension. The default is "No ISO fit" which allows the user to enter their own upper and lower limits. Other options in the pull-down are valid ISO fits based on the size of the dimension. If the user selects one of the ISO fits, then Onshape automatically fills the upper and lower tolerances and the boxes get grayed out. Onshape would have to be smart enough to know the dimension is an outer or inner diameter.

    @brucebartlett Yes, We need this in the dimensioning box as an option right now. I am getting hammered by my largest client who is a Solid Works user and this is standard.

    We have just delivered 450 x drawing sheets which each have at least 15 ISO tolerances which have all been looked up and typed manually.

    In the future this should be input at modelling level so that CAM can pick it up straight away and also carry through to the drawing sheets.

    Very important improvement. Thank you.

    I also, naively, expected to have a drop-down with ISO tolerances. But, as suggested by others - having this at modeling level would be even better!

    This is somehting that should brought back into light. This type of tolerancing is important, especially here in Europe as it is a common way of doing this when dimensioning shafts and holes, or round objects in general
