[esp-r] Re: World turned upside down....

[Jon Hand]

A model that seems to be upside down....

It would be interesting to re-trace the steps that got to this model.  Whether or not
this is possible...the lesson for all is that wire-frame views can tell lies.... there are
several reports that can help identify whether they are true.

hint one - turn on the surface normals and look to see that they are facing towards outside/otherside

hint two - look at the reported azimuth and elevations in the surface details report.  east is 90 degrees
and south is 180 degrees, floors have an elevation of  -90 etc.

hint three - check these numbers prior to spending time attributing surfaces - if you have an upside
down world you might just want to delete it and start again.

hint four - if you are putting in a floor plan extrusion check the order you put in the X Y edges (they need to
be anti-clockwise looking down).  If you put them in clockwise you will have an inside-out model.

hint five - mode QA reports are REALLY good for checking models.  Create and print out and
show them to your colleagues - they might spot something and it might take them only a few minutes.

Subject: [esp-r]  World turned upside down....

Attached is a screen shot of the first zone I have created in a model.
After entering the vertices of the zone, I changed the names and added constructions for two walls and then did the same for the Base, with the addition of linking it to the ground.
Returning to the wireframe, I now observe that the Base, renamed to Bdrm1_floor, is at the top of the drawing and Top-8 is at the bottom.
I've not rotated the drawing at all (honest!)
Please advise!
