Adding Boundary Lines to a Floor

[Anonymous]

I have a Revit LT project that requires a sloped floor, but things are not quite straight forward. The dimensions of the floor are 26' x 46' . The slope begins 5' from the West end of the floor and extends for 24' at a slope of 1" / 12". I started by drawing a 26' X 46' rectangle then used the boundary line tool to mark off the 5' flat area before the slope starts, as well as the end of the slope 24' from the West edge. But when I was finished sketching and clicked on the green check mark, I got an error saying "lines cannot intersect each other". The North edge of the slab line and the line marking the off 5' flat surface area were highlighted as being the offending parts of the sketch. 

Clearly, I am not using the correct technique to build this slab, but I am not clear on how to correct the error.  Any help would be greatly appreciated

Thanks

Bill.

Why not use Modify Sub Element's Split Line? 

...No Modify Sub Elements? Use a Roof By Extrusion then.  More than one way to skin a cat 'round here.

Can Revit LT modify sub-elements of a flat floor?

If not, you can create it as a roof, a roof by extrusion; or create 2 floors, one sloped, one flat and join them.

Well then, use a Roof instead. 

...Roof by Extrusion that is.

Thanks for your reply, but split line does not seem to work. After selecting the split tool under Modify | Floors, when I click on the floor where I want to split it nothing happens. Plus, that tool does not bring up any temp detention lines so that I know exactly were to split the floor.

I was referencing a tool that LT apparently doesn't have.  Modify Sub Elements.

You can use Roof by Extrusion, but you'll need to find the hinge(s) old-school way.

...I'm pretty sure that if you open this file that contains a shape-edited floor, you'll have access to Modify Sub Elements tools. You just can't use them to create your own floor.  Let me know if that's accurate. I'm curious.

Are you sure you have this tool?

I have managed to solve the issue by creating 3 floors and then sloping the one in the middle. Thank you for helping me as I am quite new to Revit.

You're welcome, Bill. Anytime.
