from placing curtain grids, or moving one in such a way that the small triangular
panel appears. Also, the triangle can appear if you created vertical grids and then
placed a horizontal grid that did not snap to the vertical grids.
Solution
: Cancel placement and/or movement of the grid. When dividing up
panels in a sloped glazing, it is best to start with placement of horizontal curtain
grids and then snap vertical grids to the horizontal grid.
Problem
: Typically, this problem occurs in a sloped glazing. A horizontal and
vertical curtain grid are not meeting exactly at a point, creating a small triangular
panel, which cannot support mullions.
Cannot create curtain panel in opening.
The opening is probably too small.
Solution
: Cancel placement of the mullion. When dividing up panels in a sloped
glazing, it is best to start with placement of horizontal curtain grids and then snap
vertical grids to the horizontal grid.
Problem
: You have sketched an extruded roof in such a way that a part of the
roof will lie under another part. Or you may have drawn vertical lines as part of
your roof.
All parts of an extruded roof must face
upward. Make sure that no part of the
sketch lies below any other part of the
sketch.
Solution
: Sketch the roof edge such that lines join but do not pass underneath
one another. Also, remove any vertical lines in the sketch.

Informational Message
Problem
: This warning is triggered by elements based on lines that are misaligned
—by 1x(10^-9) to .2 degrees— with either the horizontal or vertical directions,
or with a line at 45 degrees to the horizontal/vertical direction.
Element is slightly off axis and may cause
inaccuracies.
The problem can be caused by sketching or rotating elements when angle snaps
are turned off, or it can result from pre-existing elements when you do any of the
following:
■
Create an element by picking a slightly off-axis face or line.
■
Align an element to a slightly off-axis reference.
■
Explode an AutoCAD import that contains slightly off-axis lines.
■
Create floor area faces on a mass that has slightly off-axis geometry.
■
Snap defining line ends to references that are slightly off-axis (such as imported
drawings or 2 columns that are not properly aligned).
■
Snap defining line ends to references that are positioned correctly in their
respective contexts but the line between them is slightly off-axis (such as
snapping to 2 different ceiling grids).
Off-axis problems need to be resolved, because Revit Architecture cannot create
dimensions between lines that are not exactly parallel, and cannot join or cut
geometry if faces are slightly off-parallel or have very small gaps due to off-axis
elements.
Solution
: Depending on the cause of the problem, do one of the following:
■
Drag the end of the off-axis element a short distance and let it snap to the
axis.
■
Repeat the rotation operation with angle snaps turned on.
■
If the inaccuracy is derived from pre-existing elements, correct them and re-
peat the operation.
