Accuracy Thematic Display: Aquaplaning (Slope %)

Hey,

I'm trying to use the Thematic Display: Aquaplaning (with Slope % enabled) to show a visual analysis of cross slopes. The settings are like in the image below. I basically want all slopes >1% to show blue and slopes <1% red

However, in the 3D view it shows slopes larger than 1% as blue which should be red. Image:

Whenever I change the settings from 0% - 1% = blue, to 0% - 0,5% = blue. The 3D view shows the slopes to a maximum of 1% (see image).

Is this a bug, or is there a setting to make the display style a bit more accurate? [Corridor interval is set to 0,25m]

Kind regards,

Parents
  • Hey B vd O,

    In case you're still strugling with this, I wanted to show a solution that fixed my problem. It might be also helpfull for you.

    With the combination of an Item type (with a calculated expression) and a Display Style (with Display rules), I managed to get colored-indicated arrows, which are placed perpendicular on the road. The only downside is, is that you have to drop the terrain model.

    1. Create an item type with a calculated expression for slopes (this uses the 'Elevation Angle' of an element):

    Expression: "System.Math.Tan( (this.GetElement().Segments[0].ElevationAngle)  * (System.Math.PI / 180) ) *100"

    2. Create display style with Display rules based on the Item Type you made

    3. Create Terrain model with Flow Arrows --> Drop terrain model --> select all Arrows --> Attach Item Type

    I hope it's usefull. If you manage to get this working without dropping the terrain model, then I'm all ears.

    Kind regards,
