[Ra...] Posted March 15, 2021 Share Posted March 15, 2021 Call out No.34 Can i make a symmetry and a symmetry plane from the design as shown. Taking Two planes on left side and Two planes on Right side and creating symmetry plane and a symmetry. Call out a true position and use one of those as datum's and other as the feature. or would there be a better way of doing this ? Thank you guys.7.3.png Link to comment Share on other sites More sharing options...
[SH...] Posted March 15, 2021 Share Posted March 15, 2021 Yes you can, but if you are indebted to standards you have to check whether it is ISO or ASME.. Link to comment Share on other sites More sharing options...
[Ra...] Posted March 15, 2021 Author Share Posted March 15, 2021 ISO. Link to comment Share on other sites More sharing options...
[Ma...] Posted March 16, 2021 Share Posted March 16, 2021 Yes, what you could do is take the symmetry planes of the planes on the left, and do the same for the planes on the right. After doing so, you can create a plane and recall the 2 symmetry planes. After doing that, you can do what you have to in order to get the true position. This will also work with symmetry points. If you do it with points, it will take the midpoint of the 2 symmetry points and pull the true position for that. Link to comment Share on other sites More sharing options...

So, to me, it is position of the symmetry plane on the right to the symmetry plane (Datum A )on the left. Link to comment Share on other sites More sharing options...
[Ma...] Posted March 17, 2021 Share Posted March 17, 2021 Oh wow. I didn't even realize that. Guess it really was a long day for me yesterday 🤣 thanks for clarifying though. Link to comment Share on other sites More sharing options...
