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!
Same thing.
Tasks button;
Toolbar button;
Tools|Surfaces|Surface Utilities|Extract Iso-Curves;
"EXTRACT ISOLINE" keyin.
...all open the Attach Cell Reference dialog.
Plus, Under Tools|Customize, following the Application Tools tree under the Tools tab down to "Extract Iso-Curves" also shows it is using the proper "extract isoline" keyin. So, I don't know.
Might be a config thing?
YEA Carl!
I thought you could do something like that, but I couldn't find it! We don't do a lot of 3D modeling work typically, so I have to try to remember (keeps me in practice). I did it once over a year or so ago, but couldn't find it it to answer quickly!

I tried this in a clean install of MicroStation V8i SELECTseries 2 also and do not see the same problem as yourself using the delivered workspace ' Untitled '. This to me suggest that its workspace specific as you hint, may be you could try the ' Untitled ' delivered workspace to see if you still have the same issue for verification.
At the start of this thread you also mentioned 'Inroads' perhaps the problem is related to another application installed that's causing conflict.
If still unable to identify the cause I suggest you start another post including an image of the dialog that appears as this is off the original topic.
Thanks
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 ...

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.
