Drawing sheet PMI settings editor

Hello,

Need some help. I am a beginner and I am writing a journal to edit multiple PMI on drawing.

The code is written to modify Gap size of all existing Horizontal PMI. The code works when all the dimensions on the drawing are PMIHorizontal type. If I add another type of dimension like radial or non-PMIHorizontal or vertical dimensions I get error, but the journal would still modify all the existing Horizontal PMI with the new GAP value.

Please tell me what I am doing wrong.

Thanks
Bhavan
