Hello Engineer Ramiz can i use this package to make editable families for tunnel project in the “as built” stage the consultant required the elements to be editable native Revit elements “native floor , native foundation top and bottom,walls…..so on” not generic ones, is that applicable using this package.
@gkhalifah hi the tunnel and bridge is linear structral and until now we do not have ifc stander to define the tunnel object for that we can use generic model. The pakege model the linear structures and the tunnel object is adaptive family. I do not know why you need to model is as building object?
yes you are right engineer but ……. dreams of consultunat only 
Could you model the adaptive component as a mass, and then try using wall/floor/roof by face?
This example how to move adaptive points and shapehandel point

Brimohareb Bridge – Single Adaptive Point Family
This tutorial demonstrates how to create a bridge model in Autodesk Revit using transportation data from Civil 3D.
Using Dynamo for Revit, the workflow accesses the Civil 3D COM API to extract alignment, profile, and corridor information, then automatically generates the bridge inside a single adaptive family.
This approach is especially suitable for linear infrastructure projects such as:
-
Cast-in-situ concrete bridges
-
Tunnel structures
-
Other transportation infrastructure following Civil 3D alignments
The tutorial explains how to establish a parametric workflow between Civil 3D and Revit, enabling fast, accurate, and easily updatable bridge and tunnel BIM models.

New in BriMohareb_2026 — prestressing tendon geometry, end to end.
A tendon is not a spline through your points. Every control point carries a CONDITION, and that is what makes the curve a tendon:
• A FLAT TANGENT at a low or a high point
• A SLOPE where you want one — the angle the jack enters at
• A RADIUS: a true circular arc of the R you specify, and how far it runs
• A STRAIGHT stretch at an anchorage, or either side of a coupler
You control the shape. The spline only fills in between what you fixed.
Fit a plain interpolating spline through the same three points and, on unequal spans, the low point lands at 13.67 instead of the 10 you drew — and 57.6 mm lower. That is not a rounding difference. It is a different tendon, and the curvature is the load the concrete actually gets.
The new prestress_Tendon nodes put that fit in the middle of a chain:
• Read the control points straight out of a FEM software
• Measure the datum off the BIM model: a deck edge is 83.9974 m, not 84
• Re-station onto the real alignment, pinning the points you already know
• Place it in 3D, with superelevation or an inclined web
• Read back the true 3D radius and the summed angle α that friction uses
• Write the control points back to the deck
One rule holds it together: whichever tool fitted the design is the tool that refits the geometry. The nodes move CONTROL POINTS, never sampled ones — so the analysis and the drawing stay the same tendon.

New Release: Brimohareb Package – Rev. 8
I’m excited to share Revision 8 of the Brimohareb Package, which introduces a new direction for the package: structural analysis directly inside Dynamo.
This revision includes structural analysis tools based on an advanced 20×20 super-element stiffness matrix, developed especially for bridge and thin-walled structural analysis.
Advanced element formulation
The element extends the conventional beam formulation by incorporating additional structural effects, including:
• Standard beam degrees of freedom
• Warping / torsional effects
• Shear-lag effects
This allows the element to capture structural behavior that cannot be represented adequately by a conventional beam element alone, particularly when analyzing thin-walled and box-girder bridge sections.
Complete analysis workflow inside Dynamo
The current workflow covers the analysis process from:
Cross-section analysis → Element geometry → Stiffness formulation → Structural system assembly → Solution → Internal forces → Stress evaluation

The tools can evaluate the complete structural response, including:
• Axial and bending behavior
• Torsion and warping
• Shear-lag behavior
• Normal stresses
• Shear stresses
The goal of Rev. 8
My aim is to move Dynamo beyond geometry and BIM automation and explore its potential as a structural analysis environment.
The idea is to enable engineers to build parametric structural models, solve them, and evaluate their structural behavior within the same Dynamo workflow.
There is still much more to develop, but Rev. 8 represents an important step toward connecting parametric modeling, BIM automation, and advanced structural analysis in one environment
