Precisely Dividing 3D Views

[BigPicture045]

I need to precisely divide 3D views for 3D printing. I have been using scope boxes, however, I do not know how to precisely align the extents of the scope box and I am dependent on the handles which are not precise. For example I want to divide a building in half vertically and horizontally, giving me 4 parts. 

What would be the best method to do this with precision? 

I need it to be horizontally and vertically alienable to plan dimensions.

Have you check out coin auto-section box? This plugin allows you to select the scopebox and generate 3d section box from it. It is quick and easy once you get the hang of the plugin.

If you are okay with divide the building in 2 instead of 4 then it can work.

Place a grid line where you want to split > Place 2 opposing Framing Elevations at the grid > set each of your 3d view to Orient to one of the elevation view.

This is a good solution for vertical alignment cut, however, once inside the section box, the top and bottom extents - I can only set those with the handles. This means that the horizontal cuts are not precise.

Maybe export the entire model and slice the STL in AutoCAD or whatever program that can edit it.

In Revit 2024 I think the scope box has a height parameter now that can be altered directly.

Thanks - I will look into this. It just occurred to me that for Revit not to have this ability would be quite ironic because its so centered around 3D modeling. HaHahahaha.

Well conceptually the scope box is meant to define part a, part b and they usually overlap some for adjacent context in views. As such a scope box is more like a sketch...here's part A and over there is part b... Using it to slice up the model precisely for 3D printing was still a "dream" for the average person/firm when Revit got started 🙂

Edit: another thought just popped into my head 🙂  What if you create a mass element for each portion that you want to slice precisely. Use the Selection Box tool to crop the 3D view down to a mass scope element, hide the mass and then print to STL. It doesn't have to be a mass, any element that describes the precise portion of the building x/y/z you want to isolate and print. More or less a manual approach like what was described earlier using the COINS Selection box app.

I would use Dynamo for this. Basically let dynamo create a 3d View with a section box based on coordinates.

Hereunder a concept

You could further extend this sctrpt by creating multiple views with corresponding coordinates

3D views can be oriented and cropped to the extents of other views. The extents of plan views can be set-up precisely and then used to orient 3D views.
