Workflow for adding Chainage Markers & Labels

Hi Folks,

I may be imagining things here, but when I attended the GM Training Course a few years ago I seem to remember being able to add chainage markers and also label them or in GM speak "Create Perpendicular Lines Spaced Along Selected Line/ Area Feature(s)" .

I'm using V22 now and when I try to add chainage markers to a vector line I can get the markers at a fixed interval no problem, but I can't seem to be able to label the chainage markers? The GM Help  menu is pretty well useless on this  topic, so I'm reaching out to this Forum for help regarding the correct  workflow.

I seem to remember completing the dialogue box as per attached screen grab for  markers at , say, 250 m centres with "Ch." prefix and "m" suffix.  However when I do this I get the markers, but no labels.

Any and all help appreciated. ted.

Ta,

  • Hi CarrickCon,

    I'm using v22.1.0 and had similar problems but it seems to work OK if set up like below. When the layer menu comes up leave the points as unknown. Cheers rgb


  • For a marker I use create perpendicular lines in the advanced feature creation option of the Digitizer menu. Something like 50 metres works for me.

  • Thanks RGB,

    I'm using V26.1 these days and still can only get the chainage marker lines, not the labels. It's still a bug as far as I'm concerned.

    I use "Create Point Features" under the "Advanced Features Creation Options" menu as a workaround. It inserts a point AND a label at the chainage point.

    Cheers,

    Hi CarrickCon,

    Just to clarify, the label settings in the Perpendicular Lines dialog are part of the Fixed Number section, so any settings adjusted there won't be applied unless that method is chosen. It is functioning as expected, although it isn't what you are looking for.

    I have submitted improvement ticket #GM-21737 to move the label settings, allowing them to be applied to any method.
