This is more of manufacturing question in general. say I have a shaft of 6mm and I want to have it go through a gear. Should the diameter of the shaft and the diameter of whole in the gear match the shaft diameter? or should I manually introduce a clearance in the gear (or shaft) so that they can f…

John, the short answer is yes, you need to compensate for tolerances of the shaft and hole. All machine shops will need a tolerance, depending on the machining used. You could have the shaft ground, at high expense, with tolerances of 0.0005 perhaps. And you could have the hole honed to a tight tole…

When designing in shapr, should clearances be in the designed itself? or should this information be noted in the drawings? I’m thinking that its much easier (in shapr at least), to work in whole-like numbers when building prototypes than to always having to substract + add some clearance between pa…

Shapr3D are still working on drawing and tolerance updates. I don’t believe we can currently specify non uniform tolerances. i.e.: +0.000 -0.003 for example. If I were to use Shapr3D for tight tolerance design, I would use nominal design, but would allow for one part to be full + tolerance, and the …

Currently Shapr 3D doesn’t have any tolerances , correct ? I have been including tolerance using notes in the drawings. It’s a bit time consuming but it does convey the design and manufacturing intent.

ISO/BS8888 drawing standards state that all CAD items are both master (in the absence of data on a drawing) and should be middle limit on tolerances wherever possible. I believe this is due to the increasing use of CAD files being loaded directly into CNC machining, wire cutting, laser cutting, 3D …

To answer the OP question, yes you should (according to ISO standards) update the model to be the nominal, mid-limit size you want the feature to be; so hole slightly smaller than the shaft if you want to press/push them together, or hole slightly larger than the shaft if you want them to slide tog…
