New "existing SITE MODEL" with included modifiers


Recommended Posts

Hello everyone,

From PICTURE 1 you can see that I applied 2 Modifiers to the Site Model and created two 50cm deep channels. From that model I want to create a new existing Site Model. I broke the Site Model and got a triangulation (PICTURE 2) where the channels are visible, but when I create a new terrain from that triangulation, unfortunately the channels do not appear (PICTURE 3). I assume that the problem is with the triangulation, however I cannot solve the problem. Does anyone have any useful advice on how to solve the problem.

 

All in all is there a way around to how create a "new existing Site Model" with some modifiers included.

You could try changing the 3D Style for the Site Model to 3D Contours before Ungrouping it, then you will get 3D Polygon contours instead of a mesh. Reduce the contour interval to something fairly small in the Site Model settings beforehand to maximise the amount of terrain info created.

Unfortunately, that won't solve my problem. The newly created model is very bad and imprecise, even though I set the contours every 1cm.

The reason for creating a new Site Model is the quantities I have to make. The situation is very complex and new modifiers should appear above the existing modifiers, which will complicate the model itself and create a problem with quantities, considering that I need separate quantities for each segment.

Is it possible instead to build the channels in the Recreate From Source Data mode?

I don't know what kind of Site Modifier you are using, but have you tried to apply it to Existing?

Are you not then restricted as to what modifiers you can apply over the top in the proposed site model...?

If the Existing modifiers are on a separate Design Layer, you can have Proposed Modifiers that are overlapping for the Proposed Site Model. The Existing will then be part of the Site Model's Existing definition, also in terms of calculations. That way you can add detailed changes, or more specific phases of the terrain and calculations to the stage you are in. You can select the different DL, both the Existing and Proposed in the Site Model Settings. Makes it easier to turn on/off. I haven't tried to place them on the same DL. Maybe that works too? For my specific project it made sense to have the separated for this purpose.

I thought I had issues with this workflow in the past but perhaps things have changed since then or was user error 🙂

A tip by @Katarina Ollikainen in one of her videos might apply here? The idea is to increase terrain resolution in an area where a modifier would take effect:

 

Before the channel is defined in the site model, create an array of 3d loci under the channel area. Make it as dense as needed. Select them and Send to Surface. Cut/Paste them into the source data and update the DTM. Then modify the terrain, explode it to acquire the source data for the new “existing” DTM.  Or some variant might help.

@Nedim, the existing site model can't deal with completely vertical surfaces (yet), so you must offset the bottom modifier slightly (1-2mm is enough). After that, you can add the two site modifiers you created the channel with to the site model data you're using to create the new site model. Take the modifiers and ungroup them to 3D polys (must be done in a 3D view) - then you can include them in the data and they will give you nice and crisp edges.

We are working on some exciting changes to this workflow that will make it much smoother, but they depend on an overarching new feature that must be in place first, so today this is the best I can suggest. Let me know how it goes.
