[Sa...] Posted August 22, 2022 Share Posted August 22, 2022 Hello all I am new to GOM, I am trying to inspect part (ID) without CAD as shown in picture. ID is combination of cylinder and cone both. How I can construct both ?, or should I use any other command ? GOM QUESTION1.stp Link to comment Share on other sites More sharing options...
[Na...] Posted August 23, 2022 Share Posted August 23, 2022 Hello Sam1, if I understand this correctly you want to inspect the inner surface of your part? What kind of inspections do you have to carry out on this? Regards, Nanno Link to comment Share on other sites More sharing options...
[Sa...] Posted August 23, 2022 Author Share Posted August 23, 2022 Hello Nanno Yes, I am inspecting inner surface of part, I just want to know if inner diameters or surfaces are within tolerances (+0.005",-0.005") of nominal values. I am trying to inspect without CAD (Stp file). Do I need to construct circle, cylinder ?, or should I do surface selection ?. Any help would be great. Thank you Link to comment Share on other sites More sharing options...
[Na...] Posted August 26, 2022 Share Posted August 26, 2022 Hello, why do you inspect this without the CAD? You could create a fittingcylinder and cone and check them against the nominal values. With CAD a surface comparison should work. Regards, Nanno Link to comment Share on other sites More sharing options...
[Ja...] Posted August 26, 2022 Share Posted August 26, 2022 I guess a different way of thinking about this/phrasing the CAD ask is that with a CAD surface that describes this special shape you could do a surface profile measurement. ID definition is something a bit different ..you effectively have two shapes that make up the ID so it is not so easy to check. You could take an option to slice the cone/cylinder across the axis multiple timea and create multiple fitting points from the centre of the created circles , then create a fitting line to these points , then check deviations from this fitting line .
