slddrw file-how do you add a relation of a point to a centerline? 2

[borsht]

I'm trying to dimension a "theoretical" point on a centerline on a drawing, but I cant get the drawing point to "stick" to the centerline? I tryed adding a coincident relation to it, but the centerline refuses to be selected. Does anyone have any ideas? My dealer (who usually has instant correct answers)is currently working on it, but was stumped at first glance.

You could try manually drawing in a center line over the existing automated center line. Once you have done this the new center line will take the coincident relation. You could also put the center line in the model sketch. In the drawing you can browse to the sketch and choose "show sketch" you could then add relations to the sketch in the drawing and then hide the sketch so it can't be seen.

I've just tried this on a manually created centerline as well as a Displayed temporary axis, and my Sketch Point finds it and I am able to dimension a distance off the point. Weird.

Is it a centerline or sketched centerline. You can't attach relations to teh new centerline function. Sketched centerlines you can.

Also, you must make sure the view you want the sketch centerline and sketch point is active. If you put one on the sheet and one in a drawing view, you can't select both. Or one could be in another drawing as dyanmic drawing view activation can be tricky and switched views based on mouse position. Try locking the view focus in this case and put both entites in the same view.

RMB your view containing the centerline, select "Lock Focus". Then draw your point. Does Coincident work now?

It was a centerline made by useing the centerline button which is in the annotation toolbar. I tried the lock view focus(thanks for that one, ive never used it before and will find it very helpful), but that didnt solve the problem. The problem solver came by sketching the centerline, then adding the point relation to it.
thanks all

Ummm, I think it is lock view in SW 2003, actually.
Do that before you add the lines and points. Do not try to draw the ref point exactly where you want it, but off a bit. You may want to zoom very close to the site.
If you are trying to set the point to the midpoint of an existing line or arc you right click near the element to get the midpoint, then control click your point and add the relationship coincident or concentric, whichever works for you.
This is just some added detail to other responses.

Is the centerline going through circles? If so, select a circle and the point and make them concentric.

 

[borsht]

It intersects an arc, but doesnt go through the center of the circle.

I though I was following all this until your last post. If the "centerline" goes through the circle but not its center, what kind of centerline is it, how was it constructed and what is it related to?

It does sound like you may be into an issue of what mathematical "space" each of these entities exist in. it may not be logical for the program to handlea relationship between them.

If you centerline is, say a large one on a large dismaeter circle (a big dashed cross) and it happens to pass through, say another circle, I don't think you can do what you want. Those types of "center marks" are more of a fonted symbol be nature rather than true geometry as such. They have few, if any identifiable locations on them (I think just the center).

The centerline in question is not a centermark. It is a center of 2 parallel lines.
