Workplane/Reference Plane Query

Hi,

I am very new to modeling in Revit and seem to have issues in regards to understanding Workplanes and Reference Planes. I have watched some videos on the topic but can't seem to wrap my head around it.

 

in short, the issue I am having is: "I can't seem to snap to points defined by intersecting workplanes that in a program like Rhino would easily be snappable to." Considering that work planes exist infinitely, intersections between workplanes should be snappable regardless of what active workplane I have set in the current view in revit.

 

Below are images of what I am trying to model - its a doorway of sorts:

The Rhino image displays what I am trying to model, and the Revit image displays my work in progress within Revit.

 

When I set F1 as my workplane, I can't seem to draw a model line from R1 to R1B; I can't snap to the intersections between ReferencePlanes displayed in the Right view.

I am unable to upload the rfa file to the forum for some reason, so it can be downloaded here:

Thanks!

Because workplane F1 is on an oblique angle, point R1 is on a different location as where the reference planes cross.

Magenta circle indicates the R1.

I would say this shape is easier to construct with subtraction rather than with addition.

-Create an extrusion of the front view.

-Subtract with two voids.

Thanks for the solution.

 

But I still don't understand what caused the issue. It seems to be something fundamental I'm not understanding.

I assumed in orthogonal projection, clicks are projected onto active workplanes.

Such that in the diagram below, with F1 as an active reference work plane, when in the Right view, a click on the noted points (P1, P2, P3), which in my mind should be snappable as orthogonally projected intersections of reference planes, would result in projected points on F! (P1B, P2B, P3B)

Why R1 is located where it is in your image escapes me.

Thanks!

Well, the dotted lines from F1 to P1 are wrong. You have drawn these orthogonally based on the right view, but they should be orthogonal to F1. That is why R1 appears lower in your right view than the cross-section of the planes.
