    What is the minimum version of CATIA (v5 or v5-6) that runs in Windows 11?

    Hi all, I would like to know what the minimum version of CATIA (v5 or v5-6) that runs in Windows 11 is? Thank you.

    Position tolerance - Offset feature

    Sa-Ro, Assuming your part is fully defined, it does not matter where you place your basic dimensions. So both methods would be correct. However, Method 2 should be preferred. Please see the following video: https://www.youtube.com/watch?v=AfgBF0VKpbs&t=13s

    Position tolerance with axis as datum

    MattEdwards, On a different note, you should consider |A|B|C⯈| as your DRF if you are using 2009 or 2018 version of the standard. This also usually indicates that the datum features are not "selected" correctly.

    Burunduk, Yes, the line there is also an axis. That's my point, there is no difference. Maybe I can re-formulate the question: Could we call "line-in-plane" "axis-in-plane", and "point-on-line-in-plane" "point-on-axis-in-plane" instead? What does the term "line" add to the definition of a...

    profile on trimmed edge

    Burunduk, Thank you for the explanation. In that 'line-in-plane' example with the wedge, I would still call it an axis, rather than a line, because it is the intersection axis of the the 2 planes (actually 3 planes: 2 wedge planes and the symmetry plane). So to me, all datums come down to...

    profile on trimmed edge

    Burunduk, I am having difficulty understanding what a datum line is. Is the term `line` used for curve, like in `median line`? To me, the difference between a datum axis and a datum line would be that the line would have 2 end points (fixed length), where the axis would have an infinite...

    Garland23, Datum Reference System = Coordinate System (cartesian), which consists of 3 datum planes, 3 datum axes, and 1 datum point. So a datum plane for instance is just a part of the Datum Reference System.

    3DDave, I am sorry, I am not following your last message.

    3DDave, You will still have a datum reference frame with just | A |.

    profile on trimmed edge

    3DDave, If you think a datum point as intersection of 2 mutually perpendicular planes, those planes do not have to be fixed, they can freely rotate around the intersection axis, until the secondary, and tertiary datums come into play. Even if you have just a cylindrical feature (datum...

    Garland23, A datum axis is a single datum, but can be thought as the intersection of the 2 mutually perpendicular planes. Same thing as a datum point, thought as the intersection point of 3 mutually perpendicular planes.

    Burunduk, 1. What is the difference between a datum axis and a datum line? 2. For a conical feature (identified as a primary datum feature), would we have 2 datums (1 datum axis, and 1 datum point) or 1 datum (datum axis and datum point counted as 1 datum)?

    Complex geometry, do my datums make sense?

    ETUDEN, - Datum feature B is missing. - I think 0.15 flatness should be a Profile of a Surface, unless you do not care about coplanarity. Also, add 3X to the FCF. I would also remove the datum feature flag for A (no need since the 3 datum targets are very clear). - It would be much better if...

    profile on trimmed edge

    Hi all, Referring to the image showing 6 possible datums: There are only 3 possible datums: point, axis, and plane. It is important not to mix datums with datum features and/or simulators.

    DRF establishment with an inclined hole as a datum feature

    Woosang, It looks like your question is about a theoretical part, which is perfectly fine. I want to point out that next time please include the standard the part should comply to, like ASME Y14.5-2009 for instance. Looking at the part, the full DRF should be | A | B | C> |, where `>` stands...
