object rotate

Hello all,
I have a question about something I'm trying to accomplish in a drawing.
I would like to rotate or a window vertically around its center to view it
at a 45 degree angle.
I am drawing windows in a 45 degree wall (when viewed in the elevation).
The window that is on the flat wall is normal size, but the windows on the
45 degree wall
are smaller in width because of the viewing angle. If I insert a block of
a window, is there
some way of spinning this block to align with the 45 degree view.

thank you
steve

 

HiHo;
You have two options.
1.0 ALIGN is a command that will align a object with some other object.
2.0 ROTATE if one picks the midpoint of said window and enters the
rotation angle. Remember, the window must be drawn in 3d.

 

I'm only guessing that you are drawing a 2D ELEVATION, and that you are
using an elevation block that is designed to been seen perpendicular to the
projection and in this case it won't work because it needs to be squashed
horizontally because the wall is oblique to the view.

I don't like to use blocks for window elevations for a number of reasons,
but if you must, you could scale the block in the X dimension by the cosine
of the angle of the wall to the projection. In this case that's
0.707168.......

If you are picky (like me) you'll be unhappy with the results of doing this
because windows are not flat, and scaling them like this leaves them the
right size, but inaccurate representations of a window viewed on an angle.
How bad this is depends on the scale of the drawing.

 

If your problem is getting the window to come out to it's correct height and
width when viewed not normal to the 45 degree wall try using an insertion x
scale factor of .71 while maintaining a y scale factor of 1.

 

Well.....windows are materials in a series of planes, most of them
orthogonal, some further 'out',
some recessed further 'back', and some perpendicular to the wall in which
they are installed.
When viewed on an oblique some of the edges that were perpendicular
to a view straight-on, and so drawn with merely a single line, are now a
visible oblique plane needing two lines to be depicted.
Further, the protruding intersections of these planes start to obscure parts
of other planes that would be fully
visible in a 'square' view. In a masonry wall, the biggest of these would be
the masonry reveal. The leading
edge of the masonry opening will hide many, even all, of the window frame
profiles depending on the numbers.
So a window elevation block that was merely differentially scaled, would
show things that should be hidden,
and fail to show things that should be visible.
Just last week an interior designer with whom I am working on a complex
house called me "picky" for accurately
visualizing materials and assemblies from angles that weren't drawn. (I took
this as a compliment)
I'm sure many in the business would consider the above points about drafting
"picky" only not with the same tone,
but accurately drafting things in elevation that are not orthogonal is very
laborious.

 

Right back 'atchya.

 

Hello everyone,
I just want to say thanks for all the responses that were posted here, I
have tried all the ideas that were posted and it seems that "CHUCK" had the
easiest way and probably the end result I was looking for. When I get better
at Autocad, I'll define my drawing skills, but for now, this should do it.
Thanks again everyone.
