eDrawings reports 0.0 Z coord oddly, Lower left rect vertice has offset

Question asked by Ray Wilson on Jul 27, 2011

Hi Again

 

I attached a file that has the X,Y dimensions drawn next to each hole. When I do a measure using eDrawings I expect to see those numbers but instead you see the numbers plus the origin delta I can't seem to get rid of. If you measure the vertice in the lower left corner you will see the mysterious offset and the incorrect display of the Z coord. I am attaching this file "test dxf format 41.dxf" to show you what I mean. Any feedback would be appreciated, thanks. The diameters of the holes is reported correctly by the Measure function.

Hi

 

I'm new to eDrawings and I am writing a program to create simple DXF files for front panel design.

When I make a rectangle from lines and locate the bottom left at 0,0,0 the eDrawings measure tool reports the vertex at an offset (for example X = .65"  Y = 1.4" and Z = (once it was 1 meter in inches and another time it was like 4800 inches, it seems almost arbitrary). What am I missing in my file spec to let eDrawings know that the lower left origin is at 0,0,0? The drawing dsplays correctly and all the relative measurements are correct (hole to hole , side to hole, etc.) but the centers of the circles are all affected by the same offset as the lower left vertex (which I expected to be 0,0,0). And what is going on with the Z coord reporting?

 

It's probably some goofy newbie mistake I'm sure but I'm working from the AutoCad DXF spec.

 

File is attached.

 

Any help will be appreciated thanks.
