motee-z Posted November 22, 2010 Share Posted November 22, 2010 hello to all i need help how to transfer length of arc and straight line, the segment of polyline to a horizental line the length of this line is same length of polyline thanks Quote Link to comment Share on other sites More sharing options...
pBe Posted November 23, 2010 Share Posted November 23, 2010 You mean if you have polyline with a length of 175.2 you'll get a straight horizontal line with the same length? are you talking about creating a new polyline? or the the same one converted to a straight polyline? if the latter, will it keep the same inserftion point (the first point) of the the polyline? if not will you be prompted for the new insertion point? questions.. questions.. How would the world get by without questions.... just teasing motee-z but providing answers to these quesitons will give us a better idea of what exactly you wanted as the end result Quote Link to comment Share on other sites More sharing options...

motee-z Posted November 23, 2010 Author Share Posted November 23, 2010 thank you for interest what i mean i have a polyline consist of arcs and lines which form horizental axis of road in the profile i have to mark chainage of arcs begining and end on another line this line is straight and i wish i am clear sorry for my language Quote Link to comment Share on other sites More sharing options...

ReMark Posted November 23, 2010 Share Posted November 23, 2010 It sounds like you want to take the centerline stationing of the road, and thus its length, and reflect this in your profile. The road itself may have a curve in it when viewed in plan but the line will be straightened out, so to speak, when it is drawn in profile. Does that sound correct to everyone?

Sounds right to me. a developed elevation/section, but are we talking about the lines showing on the plans or section? only thing that bothers me is the arc length (if shown in plan view). if converted to straight lines how many segments would it be, i cant assume it would be form start point to end point if its shown on one long curve? I'm not CE so i'm not really sure Quote Link to comment Share on other sites More sharing options...
ReMark Posted November 24, 2010 Share Posted November 24, 2010 Perhaps you (pBe) would need some sort of civil/surveying background to understand. The OP wants to take what he sees in plan view and turn it into a longitudinal section, curves and all. Since the centerline of the road is "stationed" this can be easily done.

ReMark Posted November 24, 2010 Share Posted November 24, 2010 Sample plan and profile. The street may have a curve in it but the centerline profile does not. http://www.google.com/imgres?imgurl=http://www.cedra.com/PANDP01.GIF&imgrefurl=http://www.cedra.com/AVland.html&usg=__R53UNAtEvI8co0gflqg7CmVOh8Q=&h=734&w=1051&sz=42&hl=en&start=21&zoom=1&tbnid=o9IMcHC3TceT0M:&tbnh=105&tbnw=150&prev=/images%3Fq%3D%2522surveying%2522%252BPlan%2Band%2Bprofile%2522%26um%3D1%26hl%3Den%26client%3Dfirefox-a%26sa%3DN%26rls%3Dorg.mozilla:en-US:official%26biw%3D1653%26bih%3D865%26tbs%3Disch:1&um=1&itbs=1&ei=LPrsTJe1M8XflgflrPz8AQ Quote Link to comment Share on other sites More sharing options...
pBe Posted November 24, 2010 Share Posted November 24, 2010 Question for you ReMark. Based on the description of the OP and the info you showed us. 1. These "Polylines" have different Z values? (for elevation difference) so its not a pollyline but a 3dplolyline? 2. if the value for elevations will not be derived from the polyline itself will it be will be taken from somewhere else like Text or attribute Block? (stations) I apologize for my little knowledge of Civl stuff. Quote Link to comment Share on other sites More sharing options...
ReMark Posted November 24, 2010 Share Posted November 24, 2010 Elevations will be taken from a field survey notebook or downloaded via a total station (a high tech survey instrument). With the right software I suppose it is even possible for the plan portion of the drawing to be done in 3D thus the elevations used in the profile below could be generated directly which would be very handy and I imagine quite accurate. I did all my plan and profile work the old fashion way...transit, field survey notebook, and manual drafting (ink on mylar). Things are so much easier now.

pBe Posted November 24, 2010 Share Posted November 24, 2010 okeedokee Thanks ReMark Now going back to OP's request... In your drawing (specifically your source polyline) does it have the sufficient info to make a profile? or will it be taken from another source (e.g. TEXT. Attribute Block)? if you can give us more info that would help a lot. Quote Link to comment Share on other sites More sharing options...

ReMark Posted November 24, 2010 Share Posted November 24, 2010 It would help if the OP told us what software he is working with too. What's the big secret here anyway? Quote Link to comment Share on other sites More sharing options...

pBe Posted November 26, 2010 Share Posted November 26, 2010 [ATTACH]24812[/ATTACH]sorry for delay there is a problem in my modem So I see... its not profile after all... but a developed view (true length)... hmmmn I'll give it a try Quote Link to comment Share on other sites More sharing options...
