1/16", 1/8" increments are too small

[Tim O'Donnell]

Does anyone know of a downside to drawing this way.

Rounding errors


draw a building with several jogs and diagonal walls, and dimension re-open the dimension setup and recheck the 1/16" box and redemension...you can have errors of up to 1/2" on some walls...added up over a distance these could be significant...

so what happens in the field when one side of the building is laid out from the end and the opposite side from the other end?? who's to blame when the plumbing, heat chases, bearing walls, etc do not line up??? YOU!!
a better option is to use change the wall/opening snap unit in the setup tab of the dimension dbx to a whole value....ie 1", 12", 48", etc..

no matter how you set it up you will get fractions initially as chief joins walls at their centers...so even if you watch the display as you draw, say a 24' square house using a default wall with a nominal width of 4"...when dimensioned it will be 24'4" after it is done..much more accurate to simply use direct entry and enter whole values that way to MINIMIZE the fractions...but in real life they are going to be there



...if the builder can not read a tape down to 1/16"...it may be time to get a new builder..
