How to Convert Polyline in DWG file to Alignment in OpenRoads Designer?

If I am getting a DWG file from preliminary design and after importing the DWG file to OpenRoads, how can I convert the Polyline of proposed alignment to the horizontal alignment and change its feature definition as per requirement?

  • Depending on the length I might approach this in a couple different manners. If it is relatively short, I would probably just trace it with the complex my PI tool. If it is a little longer, you should be able to take the line work and us the Create Civil Rule Feature. Once the object is a ruled feature, you should be able to apply a feature definition.

  • Thanks for the answer, Complex by PI can be used for a shorter length of the line,  but I am not able to use Create Civil Rule Feature for longer stretch of line which is to be converted to alignment. when I try to select the line, the cursor becomes invalid. 

  • If it's a polyline with geometric elements like lines and arcs you can merge the DWG reference into master or copy the polyline into the active file and use the Create Civil Rule Feature command as long as it's in your 2D model.

  • I know in SS4 there was a limit to what the software would allow to be converted to Civil Features when importing an ALG or GPK. There are a couple variables to help with that, and some of that issue has reportedly been addressed in ORD, but I thought I would offer the variables my colleague located to assist when he encountered this issue. 

    CIVIL_RELAX_NUMBER_OF_ELEMENTS_FOR_RULES = 1
    CIVIL_RELAX_NUMBER_OF_ELEMENTS_ON_IMPORT = 1
    CIVIL_RELAX_NUMBER_OF_LINEARS = 1
    CIVIL_RELAX_NUMBER_OF_LINEARS Allows the user to relax the number of adjacent linear elements. If this is set to false or undefined then the maximum number of adjacent lines is 20. 
    CIVIL_RELAX_NUMBER_OF_ELEMENTS_FOR_RULES Allows the user to relax the total number of elements (lines + arcs). If this is set to false or undefined then the maximum number of total elements is 250. 
    CIVIL_RELAX_NUMBER_OF_ELEMENTS_ON_IMPORT Allows the user to relax the total number of elements (lines + arcs) on Import Geometry. If this is set to false or undefined then the maximum number of total elements is 1000. This only applies to vertical alignments.

  • You can convert line or polyline to element using create civil rule feature when your design seed is 2D.
