I searched, and also looked through several pages, but could not find anything relevant.
I need to have symbolised linestyles on a number of 3Dpolylines in mapping data.
We normally would simply explode the 3Dpoly's, and our linestyles display fine.
The linestyles also display fine if we change the 3Dpolylines to polylines.
HOWEVER, with the current dataset we have very high point density on our 3Dpolylines, and we need to preserve the elevation attributes of the lines.
If we explode the lines we end up with so many tiny segments that they will not display the linestyles - changing the linetype scale eventually will show the style, but at far too small a size to be relevant.
We also, in most of the layers, are not able to change the 3Dpolylines to polylines - we must preserve the 3D attributes of the lines.
So the problem is that we can't explode the 3D polylines, and we can't flatten them either, but we want the linestyles to display.
We are using Map3D primarily, but can access C3D if a solution is available there.
The precise scenario is for instance a line which is a top of embankment, but which has points at around 30cm intervals, over a line length of 206m. This particular dataset has several hundred lines like this, and the linestyle we are trying to display is a simple set of repeating ticks off one side of the line.
We are experimenting with weeding the points, but the shape of the lines is being considerably downgraded by this process.
Any suggestions will be most welcome - at this point we are most likely going to have to present this data without linestyles for these features - not our first choice.
