Hey all,
Usually I can find an answer to a question somewhere in the interwebs, but I can't seem to find one for this. I'm officially stumped. I look to you.
Is there a function within MicroStation (V8i SS2/3) that will show/draw the centerline between two curves, whether they be curves of straight lines, arcs, splines, or a combination thereof, whether 2D or 3D?
(Essentially, what's shown here http://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki/creating-a-centerline-alignment-between-two-horizontal-alignments.aspx -- but with MicroStation. Not InRoads.)
Picture a creek, or a highway where the width of the median may vary, or something like those. I want to be able to pick the shoreline or edge of the highway and automatically get the centerline of said creek or median.
Such a thing seems possible in my head or on paper, but on the screen? Any ideas?
Thanks!
Thats the right tool ( I should have said place cell not element along) but it also has place points between elements and I can used to use active point or a cell ... but the Celltool.ma from bentley works even better with a cell of say a short line using center as origin or a small circle..
I have used it to create chainages when dont have inroads as it can place the chainage or stationing ticks at an offset and at a set interval it will place straight lines cell perpendicular ..
but for this exercise the place point between would be perfect to mark out where to draw the new centre line the quickest possible way.. more points the more accurate

Not sure if there's a specific "Place Element Along" tool, but there is a "Place Points Along" tool which only places points or cells, and the "Array > Along Path" option which has been available since MicroStation XM.
did you find the place element along tool ? this is new or newish ...
The circle method was just easier than lines as you dont have to snap tangent and force the lines to stop or trim
Lorys--
Thanks for the response. Placing circles is essentially the same as the straight line method mentioned by George where you're using the diameter center instead. The more lines/circles you place, the more accurate the centerline would be, so if the computer's able to place its own [infinite number of] lines and run a true (or ideally true) center, then I think that method trumps all others, as shown in Carl's answer.

Using the "Untitled" user workspace worked. I couldn't for some reason snap to the midpoint of the construction line, but putting in an Iso Value of 0.5 is the same thing. I'll play around with it but you answered my question as to whether or not it's possible.
Thanks to everyone!
I'll have to see (if I'm ambitious enough) where the issue is with that button.
I did it another way years ago for finding the river centre between banks I did it with placing several circles by two points makes it easier to find the centers for the bspline curve later...also I think the circles finds the tangency between the lines...
there is also now the place element along tool discussed here not long ago and you can decide the number of times or interval to get your perpendicular lines I dont think the lines can ever be perpendicular to both ...
