The IRC and the IBC define Fire Separation Distance the same; the definition is very clear. When you're dealing with distance from a lot line, there isn't much you can do except play with the location of the building. When dealing with buildings on the same lot the designer is permitted to determine the placement of the imaginary line that will be used to determine the fire separation distance - I always place and dimension this line on the lot layout plan that shows all the other important fire-related stuff (fire department vehicle access, fire department connections, hydrants, maximum hose distance, etc.).

Good info, sure, but the IRC doesn't care.

Section R202, Definitions. It is the same definition as the IBC Chapter 7.

Fire Separation Distance IS measured to the Lot Line, or to an imaginary line between two buildings on the SAME LOT. Very important.

Worked for me right away:

So obvious. Thanks for the correction.

Make sure the layer Cross Section Lines is turned on - it is the "default" layer on which CA creates special cross-section geometry that can be "found" by snaps (including dimensions), though it can't be selected.

If I understand correctly you want to keep the roof ridge height and steepen the pitch to achieve a knee-wall condition. Select the roof plane, open the Roof Plane Specification dialog box, Check General>Height/Pitch/Lock Ridge Top Height, then enter the desired Roof Pitch, click OK. The final step is to adjust the lower gable roof plane intersection.

We've been saving and working with plans stored on a network since X5. No problems with X7.

In my experience the ribbon board can be specified for any depth - the bigger problem is that they are primarily for alignment, so if you spec a bigger ribbon board and need it for structural attachment of an exterior ledger, then you also need to specify to the framer how to attach the ribbon board to the trusses.

You can insert a door with the door tool. You can insert vents using the window tool.

Use the CAD Block Management dbx to select and insert a copy of the block. Explode the copy. Edit the linework, then re-block and change the name to the original block name and accept the name change in the warning dbx that pops up. All instances of the original block will be updated.

3. Select the Terrain Perimeter, open the Terrain Specification dialog box, then un-check General>Building Pad>Subfloor Height Above Terrain>Automatic, and enter 550mm into the box. This will place the terrain 55cm below the first floor elevation.

2. If you aren't worried about accurately modeling the structure, then this is easy to do with a roof plane. Set it to 0-degree pitch and place it vertically into position.

1. Select the end walls, open the Object Specification dialog box, then check the box for Roof>Roof Options>Full Gable Wall, and Structure>Default Wall Heights>Default Wall Top Height. When you close the dialog box the roofs will auto-rebuilt to gables. Then you'll have to adjust the attic walls as necessary and apply the exterior wall covering to match the second floor walls.

Do you mean an open web truss, or an i-joist? The previous answers address an i-joist scenario. If we're talking about an open web truss, then the answer depends on whether the deck attaches perpendicular to the trusses or parallel to the trusses, as well as how the end bearing condition is fabricated/detailed. Open web trusses provide superior cantilever lengths and options, depending on the depth of the truss. Can you post a drawing or picture of what you are trying to achieve?

Joey thanks for that nugget - it taught me something valuable.

If I understand correctly, select the walls you want to hang the floor off of (these will be the walls below the floor platform), open the Wall Specification dialog box, and check the box Structure>Hang Floor Platform Above on Wall.

Select the railing walls and open the dbx. Check the box Structure>Platform Intersections>Go Through Floor Below.

Are you by chance using the Blend Colors with Materials option? Check out the X7 Reference Manual beginning on page 832 for Material Painter options and modes; page 833 explains the Blend Colors with Materials option.

Have you reviewed the X7 Reference Manual, page 546, Creating a Stairwell? This section explains how to create the Open Below room on the second floor that will "reveal" the stair.

If you could post the plan file, or at least some images of the issue, it would help us with a reply.

Have you tried using the Edit Wall Layer Intersections tool to drag the stone layer to the end? When you're dealing with intersections of walls with different numbers of finish layers you can run into this kind of problem.

You can use a work-around that may give you something acceptable. Create and position three windows in a cross, eliminate the sash and frame, then mull them together. Create a slender p-solid with the stained glass material and position within the wall. stained glass cross.plan (the image used for the stained glass material will be missing - add your own)

To align the furring strips open the Wall Specification dbx and uncheck Structure>Framing>Stagger Multiple Framing Layers. I think you'll have to do this for each wall individually - I don't think there is a Default to control this, though I may be mistaken. I don't think there is any automatic control over the furred sole and top plates - you'll probably have to turn off Automatic Wall Framing and manually delete them. The flying rafters fixed themselves when I Auto-rebuilt the roof framing. Because of the roof form CA can't build the all the ceiling joists at once so that they all align perfectly with a rafter. I was able to achieve proper alignment in some areas by using Framing Reference Markers then building the framing for each roof plane individually, but other areas remained messed up.
