blown section view areas

[torpedo99]

see attached graphic

 simple road widening section

subassembly from centerline is LINKOFFSETONSURFACE out to a target alignment

next sub is good old LANEINSIDESUPER, using depths for PAVE1DEPTH and SUB-BASEDEPTH

the corridor definition under SURFACES specifies top links for both PAVE1 and SUB-BASE surfaces, but they appear to ignore that and cut across the road (see graphic) making a mess of it

do I need to add a link code to LINKOFFSETONSURFACE subassembly?  other work-around?

thx,

You have created surfaces using the Pave1 and Subbase links, but you haven't specified any data for the section between the two lanes so the TIN is forced to interpolate across the gap.

Replace the LinkOffsetOnSurface with StrippingTopsoil, Depth set to nearly 0, Foreslope = 0 and Backslope = 1  Now your corridor section will drape itself across the existing road surface out to the target alignment that you're using for the inside edge of the widening.  In the corridor add the Stripping links to your surfaces.

You could also add a hide boundary in the corridor, using the featurelines at the inside of the new lanes.

thanks for the suggestions!  much obliged

I ended up using the OVERLAYWIDENMATCHSLOPE1 assembly, then added the OVERLAY link to the surface much as you suggest with the STRIPPINGTOPSOIL work around.

works like a champ
