How to deliver Novapoint Road Models to contractors

18 December, 2014

Novapoint Road models could be exported as native model files or as LandXML. Native files gives the contractor opportunity to continue working on the road models, and calculate these towards new terraindata. The Novapoint Road model native data model data, includes all indata, relation between alignments and calculated terrain data.

4 new functions in Novapoint Road 18.20 or 18.30

25 July, 2012

The new Novapoint 18.30 works on AutoCAD 2013 platforms. This release has the same functionality as Novapoint 18.20 FP2a that was released recently.

Let´s have a look into the new road functionality that has this important release.

1. Dynamic link between two road models

You can now automatically create an alignment on the edge of a road surface or for all the end surfaces on the right/left side of a road. These alignments are automatically updated if you change and rebuild the road model. Right click on a surface in the Cross-section Viewer:

Four new choices in the dialog:

  • Save/update end of surface as alignment: creates an alignment along this surface edge for the whole project. The alignment is stored to the DTM to Group 99991 and the alignment is named after the Road model and surface name P-2.1_100 – Surface edge 2.1 and project 100

  • Erase alignment created from end surface: deletes the alignment from the DTM.
  • Save road edges as alignment: creates an alignment based on the end surface on the right and left side of the road model.

The alignment is stored to the DTM to Group 99991 and the alignment is named after the Road model and surface name P_-9.9_100 – End Surface edge left side and project 100 and P_9.9_100 – End Surface edge right side and road model 100. This surface can vary depending on whether the road is on cut or fill.

  • Erase Road edge alignment: deletes the alignment from the DTM.

These alignments can be for example linked to an external road model:

Before & After:

If the active road model is now adjusted the dynamic link is automatically updated.

Note: As these alignments are dynamically linked to the road model they cannot be used in the same road model.

The dynamic link can be turned off/on in Model – Settings – Elements Tab by selecting/deselecting the Update connection alignments.

2. Multiple road model interface – External models

External models can now be edited and calculated via the Cross-section Viewer in your active road model. Surface description on an external model can be edited by right clicking on the road surface. Road Pavement and Advanced Pavement for the external model can also be edited by clicking on a road pavement for the external model.

External models must be added/removed by selecting File – Properties and the External models tab:

When selected they will be shown in the Cross-section Viewer and can be edited in the same way as the active model. Right click on a road surface in an external model:

Select the surface for the external road model (in white) and the Road Surface description for the external road model opens. This can now be edited. The same applies to the road pavement for the external road model.

When the Calculate external models is activated in the Model – Settings and Elements tab:

All models will be calculated starting with the active model and then the first external model in the list and ending with the active road model again. After the first model is calculated select Close and the next model will build. Continue until all road models have built. The automatic calculation of the external models can be turned off by deselecting the Calculate external models.

3. Advanced pavement description

The new dialog can be accessed from the road model menu, Data – Advanced Road Pavement… or by clicking on a road pavement layer in the Cross section viewer and selecting Advanced pavement


When selected from the Cross section viewer the dialog will open at the pavement layer selected:

It is now possible to define a pavement layer in the same way as the Road bed. The number of surfaces available has been increased to 15 (16 for the Road bed).

Note: there is no End Surface for the other pavement layers. All pavement layers with the exception of the Road bed should end against the Inner slope/ditch or cut/fill line or sent up to the layer over. A pavement layer will always stop at the layer over and then follow that layer. Pavement layers cannot be defined outside the body of the road.

Note: A road pavement layer should not be sent through a lower layer.

Right click on either the Left or Right side of a pavement layer and the following choices are available (the choices are self-explanatory):

Right click on a Surface and the same choices are available:

Note: As for the Advanced Road Bed description a user defined pavement layer must have a complete definition for both sides or the result may not be correct.

4. Build of Road and Rail models

The build of a road or rail model can be started from the model menu under Model – Build, from the Cross-section viewer or by selecting Apply in a number of dialogues. Under is a description of what each build does.

Model – Build from the model menu.

The Build dialogue is opened and Wire frame and Quantity calculation can also be calculated. When external models are attached and the setting Calculate external models is selected (Model – Settings – Element) the active model is built first then each of the external models in the same order as they have been attached and then the active model once more. The build dialogue is opend for each model and any calculation errors can be controlled.

When only the Update connection alignments is selected the active model is calculated twice, once to update any connected alignments and once more to update the viewer.

Build from the Cross-section viewer.

When the button  is selected the whole project is calculated and the result build dialogue for the active model is opened.

When external models are attached and the Calculate external models setting is selected the active model is calculated and the result dialogue is shown, when this is closed the external models are calculated followed by the active model once more in silent modus, no result dialogue is shown.

Note: Connection alignments for external models will not be updated.

When only the Update connection alignments is selected the active model is calculated and the result dialogue is shown, when this is closed the active model is calculated once more in silent modus, no result dialogue is shown.

When the button is selected only the selected cross section in the viewer is calculated and the result from earlier calculation including the quantities and wire frame are deleted.

External models are not calculated.

Note: Connection alignments will not be updated.

When is selected the whole project is calculated in silent modus. No error messages are shown and connection alignments in external models are not updated.

Note: If you are working with connection alignments it is strongly recommended that the Model – Build method is use.

Rehabilitacion (overlay) with Novapoint

13 August, 2010

Our goal is to rehab an existing road that presents a bad pavement surface or a loose of capacity in one or both sides. To make it possible Novapoint has a function in road model, inside pavement definition.

Steps are:

1. DTM MADE PREVIOUSLY FROM SURVEY
2. ALIGNMENTS FROM ROAD EDGES AND CENTERLINE
3. ROAD MODEL
3.1. Road surfaces
3.2. Pavement
3.3. Adjust vertical alingment, build and check cross sections
