AutoCAD Inventor :: ILogic Rules In IDW Result In Errors

I have 3 iLogic Rules that I use with my idw's,

1-SCALE -  is to update scale in the title block

2- WEIGHT - is to update weight of model in title block

3- PDF - is to create a pdf version of drawing in same location as idw

all are triggered by saving the drawing.

These work fine, but sometimes when I create specific types of drawings there is errors, which is no big deal, just a prompt appears and I press ok and everything is fine.

With very little to no iLogic programming knowledge, is there a way to edit to rules so that if there is an issue, the rule knows it is ok and saves without the little prompt appearing?

Example of when errors occur for:

SCALE - sometimes I create drawings on my template just using create sketch, I don't place a base view so therefore there is no model information. which makes it hard to produce a scale. (see image, error -1)

WEIGHT - occurs during the same instance as above, only a sketch is saved on the idw. (see image error -2)

but I also have an error occur when creating a drawing from a presentation file. I create a presentation file from a specific level of detail from an assembly. and I get an error when saving . (see image error-3)

I understand the first 2 errors because there is no physical data to get this information from, so I am hoping an edit to the rules can bypass this issue. But the 3rd error doesn't make sense. It is from an actual model, but I guess the physical properties get lost from an .iam to .ipn?? or is there a setting that can be toggled to carry over model properties?
