Linear Template Drop Intervals?

Afternoon JeremieDL,

Thanks for spending some time looking at this,

You are correct, I was trying to use the "Linear Template" in strictly a 3D dgn (no 2D models included). I was thinking that the following workflow would work to create a ‘pit’ within a terrain, but it doesn’t:

1. In a 3D model (the only model in the dgn) I create a ‘box’ at a specific elevation, below the terrain.
2. Use the “Plan by 3D Element” tool to create an Alignment and Profile from the just created ‘box’. (however this tool doesn’t appear to create a 2D model even though the alignment and profile are created… hmm?).  The Alignment created (or at least displayed at 0 elevation, and a profile does show up in a view)

explanation of this tool:  https://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki/17488/create-horizontal-alignment-and-profile-from-linear-survey-feature

         3. Apply the “Linear Template” tool to the ‘box’ (it won’t let me select the alignment or element created from it).

This is how I understood it to   work:  https://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki/46181/video-create-grading-with-linear-template

4. By creating a “Linear Template” I was hoping to apply a corridor template to it that would then run the perimeter of the ‘box’ up to daylight, in order to simulate excavation.  I thought that this workflow would do nicely because the only variation I have to do from project to project is draw out the bottom foot print of the excavation. 

But this workflow is not working out according to plan.  Does anyone know where my logic is failing?  If a 2D model is necessary for ORD to define an alignment and profile why doesn’t the “Plan by 3D Element” create the 2D model automatically.  Or am I miss understanding how these tools work?

Any help or insight from anyone would be Greatly Appreciated, Thank You, 

Plan by 3D element will work in a 2D-3D file

Hello JeremieDL,

So you are saying if I just create a 2D model in the original 3D model only dgn this workflow will work; even if there is nothing in the 2D model?

Will, you need to start with a 2D Seed when you are creating Geometry and let ORD create the 3D "Managed Model" as needed.

Morning Mark & JeremieDL,

But by using the "Plan by 3D Element" tool that creates a Horiz. Alignment and Profile from a 3D element, and the only way it works is in a 3D model because it requires a 3D element to work?  

Sorry if I sound argumentative, I'm just trying to understand where my thought process is flawed.

Peace,
