When you have sloping walls in your model, it can be a
little difficult to add floors and have their boundary snap to the sloping
wall. You just aren’t able to pick the edge of the sloping wall where the floor
intersects.
You could go down the path of setting up levels, splitting
walls, creating new elements all to try and get this edge to snap to, this will
take a long time and often the result isn’t 100% accurate. But, there is an
easy way.
In this example the new floor is set half way up the sloping
wall and in the floor sketch creation I was unable to pick the intersecting edge
of the floor and the wall. The resulting floor is not ideal.
To get the floor to snap to the edge of the sloping wall,
just draw the floor a little bigger than you need. (So that it sticks out from
the sloping wall.
Then go to the Modify Ribbon, and pick the Join tool, and
join the floor and the sloping wall.
Now you have an edge line where the floor and the sloping
wall meet. (There is an edge on the inside too!)
All you have to do now is select the floor, Select the ‘Edit
Boundary’ tool.
And using the ‘Pick Lines’ Draw tool. Select the internal
edge for the floor. It will put a new line on the edge.
Clean up the floor sketch using the trim, and delete tools,
and finish the sketch. You now have a floor that aligns with your sloping wall.
