Dawn, this is a tricky one to answer in a short post since there are a number of factors that enter into this. In order to draw a component on a cross section all of the Features of that Component have to be 'sliced' through. If you go to Component Properties, select a Component and then List, you'll see that a Component is tied to not only the alignment or path that it was created along, but it also consists of a specific number of Members. If the alignment or Members aren't available where you cut a section then you'll get no Component display because InRoads doesn't know how to construct it. It's not that it's having 'trouble', it's just that in order to display something all of the information that is needed to create the display has to be there ...at that particular section. The DTM is not really that 'independent' when it comes to a surface created from the Roadway Designer and the Components are developed. It needs that alignment in the ALG so it can reconstruct the Component relationships and draw it. It gets even more complicated when you are using Secondary Alignments, since the DTM doesn't store any of that information in it at all. I know this is just a bunch of words (sorry no graphics) ... but each one of these display 'issues' has to be looked at on a case by case basis considering the 'needs' that InRoads has to have in order to display a Component in Plan or Cross Section.
