[Fl...] Posted March 6, 2019 Share Posted March 6, 2019 Hello, I have the questions. I want to measure the profile a surface ( photos 2) and i scan the all profile (photos 1) and i put the 2 D curve in Features, at Shape of zone i put the Bilateral one result and in Primary Datum is Base Alignment ( A I BI CI ) this is for profil of surface 0.2 A I BI CI , but for only profil without datum ( see photos 1 ) i put at the Features the 2 D curve and in Datum ref. i put No datum Referance frame or??? Is ok ???? or i can put the flatness (0.1) for all planes ( separetly ) and for radius i creat the cylinder and i put the perpenicularity (0.1)??? The all dimensioning and tolerance is in accordance with ASME 14.5 -2009 Thank you4.jpg5.jpg Link to comment Share on other sites More sharing options...
[Te...] Posted March 7, 2019 Share Posted March 7, 2019 You will do a profile to all the Datum Features and then do a second profile to no datum features, there will be a new option available in the Datum Reference Frame drop do to no Alignment just to itself.

[Fl...] Posted March 7, 2019 Author Share Posted March 7, 2019 For first profile i put at Datum reference frame the base alignment (A I BI CI ) and for the another profile i put No Datum reference .... I attached the photo. The result is same, and this don't understand and Also another questions for my profile (linear profile 2D) the circle from the photos attached îs necessary open or closed?IMG_20190306_102820.jpg Link to comment Share on other sites More sharing options...
[Me...] Posted March 7, 2019 Share Posted March 7, 2019 Just wandering, since the second line of the composite profile characteristic control frame does not control the orientation of these side walls, maybe you want to create a local alignment by either two of the side walls, and then create a theoretical 2D Curve under this local alignment, then recall feature points from the 2D curve you have to this new theoretical 2D Curve (make sure you unchecked the "re-calculate nominal value" box before you selected the points) . Then you can evaluate the profile of the new 2D Curve under its local alignment. I think this should be close enough to what the drawing is trying to control.

[Lo...] Posted March 12, 2019 Share Posted March 12, 2019 I don't think "center of mass" at the bottom should be checked. Does unchecking this option change the results? Link to comment Share on other sites More sharing options...
