Add a centerline 1

[EngJW]

Can you put a centerline in a view where there is no feature to select? The end view shows a bore through the part, but in the side view several features need to be dimensioned off of the bore centerline. Selecting the side view and then selecting the bore in the end view does not work. All I can think of is to manually draw the line.

Thanks

Use the centreline icon in the Annotation toolbar ... all you have to do is select the two outline (hidden) edges, in the side view, which define the bore. The centreline shouldl automatically be placed. Once drawn, the centreline ends can be "stretched" to suit.

& all the best.

What coreblimeylimey suggested works, but I normally draw a construction line and then add a symmetric relation between it and the same 2 hidden lines. I prefer using the construction because you can dimension to it and also add relations to it, you can't add relations to the centerline created out of the annotation toolbar.

That must be why I have been having trouble dimensioning. I have been picking centerlines and points (old Autocad practice) instead of the feature. Another step up the learning curve. Thanks.

mncad ... You should be able to dimension to the Annotation-created centreline ... I can!

You can also "switch on" the Temporary Axes & use those to dimension to, but the Annotations Centreline icon is the better way to go, as it can be placed just where needed. The Temp Axes method makes ALL axes visible.

Also, out of curiosity, why would you want to create relations to a centreline in a drawing view? All feature relations should be made in the model.

& all the best.

corblimey,

Because of what we design I sometimes have to pick the centerline and a feature to the right or left of center, then make the dimension show as a diameter, you can't do that with the Annotation created centerline, only a sketched centerline. We also will have holes that are off at odd angles so I use a line that is related perpendicular to the centerline to create an auxilary view for calling out position.
