Details of the software products used to create this PDF file can be found in the General. To answer a question how datum B should be simulated, you need to look at Datum Reference Frames, which contain datum B and associated modifiers (if present). You’d need to simulate it with “true geometric counterpart” – inverse shape which contacts the surface at its actual location (unrelated actual mating envelope) I’m pretty sure that datum A shouldn't be simulated with 1mm offset. This would make measuring a lot easier, actually.ĭatum feature A is a complex feature and without CF it must be used in its entirety. If your drawing contains these targets, use them. If the modifier had not been used, the datum A would have been the axis of the associated cylinder.” This median plane contains the set of axes of possible associated cylinders (with variable diameters) from the datum target points. The first plane contains the datum target points the second plane is the median plane of the datum target points, perpendicular to the first one. “, the datum A with modifier is a set of two perpendicular planes and not the axis of a cylinder. Presence of a modifying symbol CF (Contacting Feature) in the feature control frame implies that some portions of datum feature are used to simulate datum and contacting features should be specified on the drawing. RE: Help with Drawing Datums.? J Macias (Mechanical) 23 Apr 19 21:56 And how I set this up in our software (gom inspect) seems impossible.

The datum B must be perpendicular to this plane (right?)ĭatum B in my mind would constrain the part with a datum simulator as a 5mm larger surface offset of the radius J-K but this would still allow its centre axis to float and also its rotation to float? Does it? (head starting to hurt!) So this would sit against the vertical face on the left (ie the plane created by point 'C' with some float on this plane (fitting within the 1mm offset surface profile) so in my mind this feature c-d will constrain the part to a datum simulator of this surface 1mm larger than the surface form of C-D. please see below:Īs you can see the Surface profile datum reference A is defined by a rotated surface profile of the surface C-D. I'm still having some issues understanding this however and I think i should hae shown a little more of the drawing in image 1. Thank you so much for the feedback its all very helpful. RE: Help with Drawing Datums.? chez311 (Automotive) 18 Apr 19 18:47 CF identifies a group of 2 or more features of size and treats them as a single feature (interrupted diameters for example) UF symbol belongs to ISO, the closest equivalent, but not the same, in ASME is CF - Continuous Feature. You'll find information about the placement of datum feature symbol in ISO 5459:2011 7.4.2.1 (ASME Y14.5-2009 3.3.2)ĪSME and ISO standards are virtually identical when it comes to datum. The meaning is the same if the datum feature symbol was attached to the feature itself. In your first image the datum feature A is the area between C and D defined by true profile (Radius 26.5) and it is similar in the second image: the area from J to K (Radius 5 - non-continuous but used as a single feature to create a datum). It indicates that a datum feature is the feature controlled by the geometric tolerance.

Datum Feature Symbol (Datum Indicator as it is know in ISO) can be attached to feature control frame.
