[Al...] Posted October 13, 2023 Share Posted October 13, 2023 Normaly it would be simple, you would just use Intersection function, select Torus and select plane at which you would want to cut this torus (choose result in a process, with or without shell function) and that would be it, but you cant choose Torus in intesection construction. So, how can I create a small circle on a torus? Link to comment Share on other sites More sharing options...
[To...] Posted October 13, 2023 Share Posted October 13, 2023 Use Define Circle on Cylinder. Click on torus where you want circle. Choose Subsidiary Radius. Footnote: Torus does not play well with others.... Link to comment Share on other sites More sharing options...
[Al...] Posted October 13, 2023 Author Share Posted October 13, 2023 Thanks for the reply, but now I've got newly created circle which needs measurements, but I have already measured Torus and now want to extrapolate that circle from it...

[Da...] Posted October 13, 2023 Share Posted October 13, 2023 Do you have a sketch? What is your goal? primary radius or secondary? Link to comment Share on other sites More sharing options...

[To...] Posted October 13, 2023 Share Posted October 13, 2023 Please sign in to view this quote. Assuming you measured the torus using Small Circle Paths. Open the circle, under options, select Recall Feature Points. Right-click on Torus and select Open. Select one of the paths. Click OK. Link to comment Share on other sites More sharing options...
[Al...] Posted October 17, 2023 Author Share Posted October 17, 2023 I don't have / don't see option for selecting which circle I want to recall, I only see big torus circle (large circle diameter) when I recall that's what I get, large circle which I do not want to recall..

[Al...] Posted October 17, 2023 Author Share Posted October 17, 2023 Please sign in to view this quote. secondary radius (I know how to get it to calculate small or large circle radius but I want specific circle(or elipse on a torus)). Link to comment Share on other sites More sharing options...

[Je...] Posted October 17, 2023 Share Posted October 17, 2023 How did you measure the torus? What was your strategy? In almost every instance I have seen, measuring the 3D torus feature is unnecessary and only the subsidiary radius is required. In which case the proper method was described earlier by Tom. Please sign in to view this quote. If you are looking to utilize your current data, this is dependent on the strategy you utilized. If you used multiple subsidiary radii scans around the primary diameter then recalling a single segment is achievable. Features > Circle > Recall Feature Points > Right click on Torus > Open... Select a single scan. This will be "D2" If you used primary radii scans then you will have to create intersection points with a plane using each individual segment then create a circle from those intersection points. 1. Features > Circle > Recall Feature Points > Right click on Torus > Open... Select a single scan (this will give a large circle that more closely coincides with "D1" - Repeat for all scans. 2. Features > Plane > Theoretical Plane > Input criteria to make plane perpendicular to your torus so an intersection would give "D2" 3. Construction > Intersection > Plane + D1 Circle - Repeat for all created Recalled circles. 4. Features > Circle > Recall (maybe Feature Points - try both) > Select all intersection points. If you utlized any other type of strategy this likely gets a bit more difficult and I advise remeasuring using a proper strategy if possible. In the future, it is just easier just to measure the subsidiary radius directly. Link to comment Share on other sites More sharing options...
