Showing the Room Divider as a single line

[Ed_Orum]

Hello again,

I would like to show the room divider as a single line, but after I draw the divider (I draw it in the center of the wall I want to divide), it shows up as two lines, and the two lines line up with what the program generates as basically a wall.

I want a true divider, so I can place it where I want it in relation to say the end cap of a wall, and it will actually show up where I place it, and as a single line, not as a double line.  I checked all of my default settings, wall settings, etc. and I can't see anywhere it is a double line.  But that's what shows up.

How do I fix this?

Thanks,

Lane

I normally see that when there's a change in the ceiling or floor height relative to the adjacent room, the single line will become a double line full thickness wall. In those cases there's no way that I know to change it back to a single line.

When I tried this, the room divider remained a single line, but the rooms have the same floor and ceiling heights.

 

If you don't have a difference in the floor or ceiling height in the room, maybe post the plan so we can take a look.

This used to baffle me as well..... In my experience that happens when an attic wall is generated above for some reason such as in situations like @Chrisb222 said.

You can always try using a new wall type that is only 1/16" thick.  Might not be structurally accurate for all situations but would look how you want in a plan view.

This is finally what I've come up with:

 

 

 

The reason for the drywall layers is to make wall ends generate correctly on interior walls.

It starts with a single line and seems to always revert to the thickness of whatever wall type you used. JLU_Design's method works fine. If you don't need drywall, just use a thin main layer.

For those that are curious, it changes to a double line when you have a difference in setting from the rooms on either side of the wall

[ProPlan_2011]

FIrst attempt:

• draw room divider
• change one room's height (divider now double line)
• edit room divider: create new wall type: 'Invisible wall test', insulation air gap 0"

result: upon exiting the dialog, the wall reverts to an interior 4" with double dotted lines

 

Second attempt:

• first create new wall type: 'Invisible wall test', insulation air gap 0"
• draw interior 4" or whatever regular wall (except room divider)
• change one room's height
• edit room wall (divider): change it to wall type: 'Invisible wall test'

result: upon exiting the dialog, the wall retains its definition as 'Invisible wall test', a room divider 0", with a single dotted line.

 

Note: This was a simple test and I did not investigate any consequences of this approach.

This may help...

Have a play with Wall Specification>Structure>Platform Intersections>Generate Between Platforms.

Platform Intersections

These settings control the relationship between the selected wall and the Ceiling Platform above and the Floor Platform below it. They only take effect when the selected wall is positioned at a platform edge, such as at the exterior of a building or Open Below room. See Floor and Ceiling Platforms.

• Check Generate Between Platforms to fill in the gap between floor and/or ceiling platforms when the selected railing or invisible wall separates rooms with different floor and/or ceiling heights. When unchecked, this gap is not closed. Only available for railings, Invisible railings, and Invisible walls, this setting has no effect when the selected wall type has only one layer.

any setting? I am seeing this at top of stairs for a room to below room

 

My room elevations are the same for the rooms

 

 

 

I notice when I specify a room divider as the walltype, CA changes it to Interior 4 if I go back into the dbx.

 

 

 

 

This is causing the pony wall to extend beyond the stairs.  

 

I did what JLU did and it works, but my question is, why do I have to?

because the most common reason for such a change is that you want your interior wall type to create a structure and surface at the exterior of whatever discrepancy there is between rooms...i.e. drywall over framing when a floor is sunken.
It's not specifically reverting to interior-4, it is reverting to your default interior wall

would that mean everyone has to do this at the top of stairs?

 

I'm thinking there is something odd here, maybe because it is against an outside wall with a basement foundation that is wider ....or something

I would think typically people use the automatic stair opening tool in the edit toolbar

there you go, learn something new every day. I will try that, merci. For some reason I thought it was automatic, but may that is only if it is a railing
