Road Marking task in Quadri

What

You need to create a Road Marking task in Quadri in order to store 2D markings. 

Where

The task are created in Quadri. Go to the NOVAPOINT ribbon and select Road Marking under Road & Rail. 

How

Road Marking task can be created the following way:

Step 1:  Go to Quadri.

Step 2:  In the Explorer, select the correct summary task for the Road Marking task.

Step 3:  Go to the NOVAPOINT ribbon and select Road Marking from Road & Rail.

Step 4:  Enter a suitable name.

Step 5:  Select subtask.

Step 6:  Click Finish to create the task.

The Road Marking task can now be used to store 2D markings created by Novapoint Road Marking using the Save to Quadri command.

How to make 3D markings

You can create a 3D version of the markings you have saved on a road marking task by using a procedure that move features vertically along the z-axis.. This is done in Quadri for Windows by using the "Move Vertically" function that can be found in the "Terrain Tools" under the "Modelling" tab.

Tips for better results

There are two main reasons why marking is not correct in 3D:

• The marking extends beyond the calculation basis.

• The calculation basis consists of many surfaces.

The road model creates a model for each surface number… and the “Move Vertically” function doesn’t like working with so many surfaces at once.

So a recommended solution to reduce the number of surfaces in the calculation basis is, for example, to use the road models' "StakeoutdataLinesSurface" as the input data for the calculation basis of a separate terrain surface that can be used by the “Move Vertically” function.

“Move Vertically” will have a much better chance of successfully working against this surface. It is worth noting that this method will also fill in any small gaps in the resulting data from the road model.

This surface can also be used when placing signs in 3D.

It is important that all markings are inside the outer boundary of the calculation basis. For example, if parts of the markings are outside the outer boundary of the calculation basis, the "Move Vertical" function will not find any height data for this data. 

The situation is illustrated below:
