get offset target's autocad objectID from subassembly

[wang890]

what i am trying to do is i have a joint polyline with different segmental thicknesses, 4 thicknesses total, each represent a different soil type and a different subassemblies has to be applied. i can divide regions in my corridor but the problem there are over 1000 segments on this polyline with different thickness (width).

so my thought is make a custom subassembly. and add this polyline as an offset target (polyline follows alignment). however i only need to extract the instantaneous "polyline width" at that corridor section. so i can apply the condition and then draw links, points, shapes. from that.

so is it possible to obtain the objectID of the polyline with corridor built in subs so then i can figure out how to get width no problem. done convert objectID to object with the autocad.net.

i looked around the only places that the target is related are (just giving an example. i will use some other name of course for the target):

1. get input

  oParamsDouble.Add("ShoulderWidth", ShoulderWidthDefatult)

2. calculate offset, which mentions the offsettarget object.

IfNot oShoulderWidthTarget IsNothingThen

Dim dOffsetToThisAlignment AsDouble

Dim dXOnTarget AsDouble

Dim dYOnTarget AsDouble

IfTrue = Utilities.CalcAlignmentOffsetToThisAlignment(oAlignmentId, corridorState.CurrentStation, oShoulderWidthTarget, Utilities.GetSide(vSide), dOffsetToThisAlignment, dXOnTarget, dYOnTarget) Then

Else

Utilities.RecordWarning(corridorState, CorridorError.LogicalNameNotFound, "TargetHA", "ShoulderExtendAll")

                    dOffsetToThisAlignment = dFlip * vShoulderWidth + oOrigin.Offset

EndIf

If vSide = Utilities.Left Then

                    vShoulderWidth = oOrigin.Offset - dOffsetToThisAlignment

' Judge whether or not the left alignment is left to the base alignment

If dOffsetToThisAlignment > oOrigin.Offset Then

Utilities.RecordError(corridorState, CorridorError.ValueInABadPosition, "LeftMedianWidth", "ShoulderExtendAll")

Exit Sub

EndIf

Else

                    vShoulderWidth = dOffsetToThisAlignment - oOrigin.Offset

' Judge whether or not the right alignment is right to the base alignment

If dOffsetToThisAlignment < oOrigin.Offset Then

Utilities.RecordError(corridorState, CorridorError.ValueInABadPosition, "RightMedianWidth", "ShoulderExtendAll")

Exit Sub

EndIf

EndIf

another way is make a program to divide regions and maybe even associate the corresponding subassemblies. i have never done this before and not sure can be done. but then to get the station start and end for each region i need to make another program to read the polyline then compare to alignment and get the station where the thickness changes. also will take a lot of time to make. besides 2 out of 4 conditions right now i can't use any stock subassembly ot do.

using visual basic 2010 express, civil 3d 2012.

this is gonna  be one interesting subassembly.

anyways just putting it here to see anybody have any idea. i will be working on this next week and looks like it's gonna take a while to do. i always get these super complicated stuff to do on top of other work.

lol.

right i hit ok then i found that the "targetID" is the objectID.

it's the only property in widthoffsettarget, duh

x (

now off to the autocad group to find out how do you get the instantanous polyline width, by having the station NE point projected to the polyline.

i guess i can just select all the polylines (keeping them seperated), then i think civil 3d can pinpoint down the only one that falls at that station. doesn't it? then good to go. doesn't look like it goes through all the targets selected for each station

looks like the

   oShoulderWidthTarget = oParamsOffsetTarget.Value(

"TargetHA")

already done the filtering?
