Do I feel your pain discussion group groupies?

I am one of those guys who grew into the business drafting on velom with lead so CAD drawing is a little alien to me. However after saying that I have been drafting with AutoCAD for a few years more than 3 less the 10. So I should know what to expect form some of the basic commands, drawing in 2d not 3d. Please don't go there that is why I got Revit. I am using Revit architectural Suite 2009 for Vista 64 bit system. Here is what is happening;

1. Fillet and chamfer work on a part time basis each displaying a "noncoplaner lines" message when they don't work. One kind gentleman ask me check the DUCS to make sure it was off and it is. It apprears to me AutoCAd is think ing the z axis when I am drawing in the x,y axis

2. Object snap regardless of the snap selection at times only snaps on what it wants to snap on. Probably related to #1.

These seem to be the basic command problems I am having. I would love to be able fix them mysefl. I have looked into the self help CAD books but cannot find anything nor am I sure where to look. So basically I depend as others for help from the disscussion group folks or better yet Autodesk Guru's. Since I have posted the chamfer problem previously I received some responses of having the same problem so they used fillet instead. Unfortunately my fillet does the same thing. Yes I feel your pain discussion group groupies.

To ensure that your 2D drafting is always being placed at a z value of
0, the OSNAPZ system variable should always be set to 1. There is a
little blue icon in the lower right corner of AutoCAD that toggles this
also. When this is set, even if you snap to an object point that is not
in the x/y plane (i.e. 0 z) that z-value will be replaced with 0,
keeping your 2D drafting truly 2D.

Thank you Mason, your tip with the right hand customization work. We shall see about this.
Again Thanks fory our response

I have check the osnapz setttings and it is and was set at zero. So I am still having non function problems with chamfer and fillet and the non colplaner message. Must be something to this.

Fillet and chamfer won't work unless your linework is actually coplanar.
Setting OSNAPZ to 1 will only affect newly created / modified
entities. You will have to select all your linework and manually set it
to a z value of 0. I haven't used it, but it seems the FLATTEN command
would be the easiest way to accomplish this.

only use flatten on non aec entities. ie autocad lines arcs etc. It will
kill aec objects.
Also use it in plan view.

Mason picked it up anyway but you need to say that
you are using ACA 2009 or Autocad for Architecure not Revit.

(you may be flamed 🙂

The 'suite' is a marketing package - it's a group
of several software packages.

Revit is an entirely different package to ACA and
has it's own News group.

ACA includes autocad as a base with the ACA bits on
top. 

 

To your problem, interestingly you can trim with
non coplanar objects so I don't see whythey need to makea fuss when filleting.
but there you go.

mere technicality!

If they don't intersect, how can they be trimmed
:-)

There have been many times when I didn't need to
care whether they were at the same z and I wanted them to be
filleted.

Probably fair to say many of those times they
should have been,.... but not all.

The fact is that if it can do it with trim it
should be able to do it with fillet.

It's only math.

Trimming (which back in the day also did not work with non-coplanar objects) trims to the "apparent" intersection (intersection of the lines projected into the current XY plane). A FILLET with radius set to 0 is the equivalent of a double TRIM, so I suppose that if they wanted to bother, they could fuss with the FILLET code to do that. But FILLET with a non-zero radius would need to draw an arc, which would want to be in the same plane as the two lines, which does not exist for non-coplanar objects. Again, I suppose that the arc could be drawn in the current plane, relative to the projections of the two lines into the current plane, with the lines then being trimmed to their apparent intersections with the arc. But that is a lot of fussy code to glom onto AutoCAD just to cover what is likely a drafting error that should, in my opinion, be fixed. But you could always post this to the Wishes Discussion Group if you feel it would be useful.

I set my OSNAPZ TO 1 as recommended and typed in the FLATTEN command only to get a response "unknown command".

Very intersting especially since all of my work is on the x,y axis. Something doesn't make a loat of sense.

What version are you using.

Flatten is probably an express tool
command.

You need to load them as they are indespensible -
all of them.

when you install you need to do custom and add
Express tools to the install set.

Stick your install disk in and add it to your
installation.  I think you untick everything else?

Yes it could draw an arc with 2 end points at
different z planes.  That might not be pleasant.

Same with chamfer.  possibly why they left
them alone.

Use the button to suppress the z in the
future.

I can find no toggle and autocad LT2012 help does not have any answer for osnapz?

There is no OSNAPZ in LT: if you want it, you need to upgrade to the most expensive AutoCAD and other verticals.
