Hi,
I've created a template that will alter the verge crossfall from 0% when earthworks in cutting and -2.5% when the earthworks are on embankment.
When the template switches from cut to fill though I get gaps in the verge and earthworks, I've tried everything I can think of but it's blowing my mind now!! :)
I've attached a few screenshots below of my issues below, any help would be greatly appreciated! Many thanks
Hi Ryan
Any chance you can send me the DGN to have a look at please. I should be able to template deatils from it t onvestigate for you.
I think you may have my email address ? If not let message me her and I'll drop you a mail.

What software are you using?
This is a flaw in OpenRoads that isn't just confined to earthworks. If affects all trims and display rules.
The workaround is to add key stations immediately ahead and back of where the earthworks transitions between cut and fill, say around a 1mm offset. But this willl still leave a small 2mm gap between the different elements. Not ideal, and creates a lot of manual work, but it's the only solution Bentley are offering at the moment.
An alternative would be to use a feature name override to create a single element instead of different cut/fill elements. Not tried it yet myself, but I think there is a video on the learn server somewhere.
On the components, try turning on 'Use Name Override' and give the same name to both components i.e. the one in cut an the one in fill. (This is similar to 'feature name override' - as mentioned by Stewart - but applies to components)
Another method is to use End Condition Exceptions (transition type) should you need to keep cut/fill component as separate entities...
I managed to reduce the issue, but not eliminate it completely.
You could use Name Override for the verge component and Feature Name Override for the back of verge point.
This will allow you to display a transitional mesh for the verge surface and a transitional line for the back of verge.
Then I would use a combination of auxiliary "DNC" components with display rules and Feature Name Overrides for the end condition points that transition from cut to fill.
Note that in your case I would use the range 0.01% to -2.5%. I would avoid the 0%.
These last points would have the same offset as the verge width and the same slope as the verge. The DNC components would essentially match your verges and they would allow you to introduce the cut and fill intercepting points for the transitional areas.
This approach combined with a frequent template drop interval could allow you to almost eliminate the problem and create separate ground interfacing strings for the cut and fill scenarios.
