Surface Rebar Cover #61

Open nmeek opened 8 years ago

nmeek commented 8 years ago

Please provide a method to get the rebar cover values for faces

moethu commented 8 years ago

Hi nmeek, thanks. this would change the workflow from creating curves first to creating rebar directly, reported here already: #34

nmeek commented 8 years ago

I should have been more specific. I would like to get the rebar cover value associated with a given surface in order to place the bar at the correct clear distance rather than an arbitrary distance.

Thanks, I'm discussing this with other Users - some requested this feature already but it would change the workflow. The offset Parameter controls the distance between surface and centerline of the rebar. since we are creating curves in the first place and rebars at the very end - we do not know about the rebar diamater when we are creating the curvature. changing this isn't difficult but it would require creating rebar earlier and therefore the nodes would be less flexible.

I apologize. Again, I should have been clearer. I would like a method to GET the rebar cover value for a given surface. I have found that I can retrieve arbitrary cover values for a given element but can not find a way to determine which cover value is appropriate for any given face. rebar cover I agree that the offset value is appropriate for the bar location, as the bar shape is defined by a curve. However, when calculating the appropriate offset value for the bar I would rather use the appropriate clear distance (minus the radius of the bar), as defined in the project for the hosting element, rather than hard code an arbitrary value.

As this is a different issue than the one you referred to, could you please reopen this?

moethu commented 8 years ago

@nmeek ,sorry for getting back on this so late. I added an "Offset to Cover" Node helping to create bars with a cover parameter instead. But I guess that's not what you are looking for?

nmeek commented 8 years ago

Unfortunately, it is not. I am looking for a node to return the value of the length parameter of the RebarCoverType associated with a selected face. This is an inquiry of the hosting concrete geometry, and has nothing to do with bar placement.

I can get all Rebar Cover Types from the project, all cover parameters defined for a selected element, and clear distance for any given cover type. What I can't figure out is how to determine which, of these clear distances, is appropriate for a given face of the solid.
