Unitless blocks on tool palette scale based on drawing units

[BrianHailey]

I have a drawing full of blocks, which are all unitless. The blocks have been added to a tool palette. When I insert the block into a unitless drawing, it doesn't scale (which is good). When I insert it into a drawing that has the units "Feet" assigned to it, it doesn't scale (which is good). When I insert it into a drawing with the units "Inches", it scales by a factor of 12 (which is bad). I have no idea where the block as the unit "Feet" associated with it. The drawing it's in is unitless and the block definition is also unitless. My understanding it, this block shouldn't scale no matter what the drawing units are. I've played around with the -dwgunits and no matter what that is set to, the blocks scale based on the units command. I've done this in our template and a drawing created with no template. I created a new tool palette and tried it from there with the same results. I'm missing something, I just don't know what it is.

INSUNITS variable, look it up in HELP, may be what you seek since you never mention it.

What about INSUNITSDEFSOURCE and INSUNITSDEFTARGET ? They are registered. To set to 0.

[BrianHailey]

When I refer to the drawing units, this is what I'm referring to, which is the same as INSUNITS:

Both INSUNITSDEFSOURCE and INSUNITSDEFTARGET are set to 0 and the scaling still happens. I did a bit more testing and if I create a new block, the scaling doesn't happen so it must be something with my blocks and not necessarily something with the drawing they are being inserted into.

Another thing, when I use the INSERT command, browse to the drawing with the bock in it, and insert it into a different drawing, the scaling doesn't happen.

Even more information. I inserted the block that is scaling based on the units (when it shouldn't be) into a new drawing and then added that block to a tool palette and the scaling doesn't happen. Could it be a setting in the source drawing and not the block itself? The drawing is saved as a 2013 drawing to be compatible with some projects we are still doing in 2016.

Very odd. I had to open the drawing that contained the blocks using 2016, audit, and save the drawing. Things seem to be working now. Not sure what happened.
