Civil Geometry challenge??

Adam Wieczorek

It looks to be very easy to do. 

I have a number of “driftplaces” to design – it sounds like a perfect job to be done with Civil Cells.

 Unfortunately I can not layout simple geometry as marked in yellow on picture below. I tried to use line from element, line to element tools to create this tangent to arc and 45deg skewed to edge of pavement line – for some reason tangent snap is fadedout and can not be used with these tools. I did not succeed using other transition tools. Was trying with civil accudraw, but no effect as well.

 Any tip would be helpful.

    Couple of things I would try.
    1. You can use the line from element tool to construct the line skewed at 45° from the EOP.
    2. Do you know the offset the yellow line is from the EOP? I see 7.5 labeled but that looks like the lane width. If you knew the total offset you could create a construction graphic at that offset.
    3. Then you could use the arc between elements tools to construct the circular portion.

    Marc. thanks for response.

    1) Line from element to construct line skewed at 45° would be perefect if only could work with tangent snap;
    2)Offset from EOP to Yellow arc will vary, depending on carriageway width;

    it really looks like an easy task to do but I can not accomplish that with Civil Geometry tools and that would be desired if I need Civil Cell.
