[FR...] Posted January 21, 2020 Share Posted January 21, 2020 Hello, I am trying to define the upper and lower tolerance of a plane when I create a new plane. But the tolerance area is unable to key in any value there. Is there any way to key-in tolerance same as i did for 3D curve? attached is feature of 3D curve & plane.

[Ja...] Posted January 22, 2020 Share Posted January 22, 2020 Use the checkbox to the left of the component of the plane that you wish to assign a tolerance.

[FR...] Posted January 22, 2020 Author Share Posted January 22, 2020 Jacob, Which checkbox you mean? Please detail it. I did try these boxes but no responses.

[Ri...] Posted January 23, 2020 Share Posted January 23, 2020 Just be aware that the X, Y, Z values of a Plane are from its FCS (Feature Coordinate System) which is not the same as if you created a Perpendicular Distance from Plane to Plane. The FCS for a Plane is going to be in one of the 4 corners that you will see if you open up the Plane. If you are wanting to get the true linear distance of a Plane, I would start with using the Cartesian Distance Characteristic.

[FR...] Posted January 23, 2020 Author Share Posted January 23, 2020 Thank you Richard! Where is FCS in feature of plane box? And also in the free form feature box, i want to define the surface profile of free form for 0.005 (+0.003/-0.002), which is not be able to define in the characteristic tab, as in characteristic I tried to use unequal distribution function and it give me (-0.003/-0.008) tolerance in stead of (+0.003/-0.002).Question is, how to define a unequal tolerance for free form?

[Me...] Posted January 23, 2020 Share Posted January 23, 2020 Please sign in to view this quote. The Cartesian Distance Characteristic is almost useless, IMO. It reports the distance between the feature origins and doesn't take into account the orientation of the features. If you have 2 planes that are supposed to be parallel but are out by 10 degrees what distance does it report between them? The maximum? The minimum? Nope. It reports the distance between the origins, which is arbitrary. Same with 2 parallel lines, etc. That's ok if you're dealing with small surfaces and large tolerances. But I find it to be misleading and inaccurate most of the time. I use True Position for almost everything. It reports the worst case and considers the orientation and condition of the geometry selected.

[To...] Posted January 23, 2020 Share Posted January 23, 2020 Cartesian Distance between 2 planes works exactly the same was as a Perpendicular Construction. They both will create a distance that is from the "mid-point" of Feature 1, perpendicular to Feature 2. So, if the 2 planes are out by 10 degrees, there really isn't much hope of getting the right distance between the 2 planes, Link to comment https://qualityforum.zeiss.com/topic/16644-define-a-planes-tolerance/#findComment-92992 Share on other sites More sharing options...

[FR...] Posted January 24, 2020 Author Share Posted January 24, 2020 Thank you so much guys! Distances meaning with Calypso is always a question mark when i first learn it and I did not spent time to dig. Thanks for sharing infos. For free form unequal profile tolerance 0.005(+0.003/-0.002)definition, any suggestion there?

[FR...] Posted January 28, 2020 Author Share Posted January 28, 2020 Well I would assume that there is no solution for Calypso to define unequal tolerance for free form surface then...

I am not sure if you can apply this to a result, but you can definitely see which direction each plane is leaning with regard to their normal vector. example Link to comment https://qualityforum.zeiss.com/topic/16644-define-a-planes-tolerance/#findComment-93004 Share on other sites More sharing options...
