    Working around model fill pattern minimum dash length

    I suspect the answer to my question is, "that's impossible" but hoping someone will have a creative solution for me.

    I'm trying to make a series of model type fill patterns that I can apply as a surface pattern to perforated plasterboard. Several of these patterns have circles and/or elements smaller than the minimum dash length of 8.383mm (1/3 inch). The attached .pat is an example of a pattern with 13.5mm dia holes that I originally tried to replace with circumscribing octagons...problem is the octagon sides were 5.6mm so the pattern came out looking like the attached pic. So now I'm just using squares which is unfortunate because I have a 12mm actual square pattern that looks identical now. I have another pattern with 6mm holes and another with 5mm wide am I supposed to model that??

    Things I've noted:
    - It is possible to make dashes smaller than 8.383mm if the space(s) is/are also smaller than 8.383mm (they never are in my patterns). If both values are below 8.383mm then Revit, for some reason I cannot divine, will switch the first dash and space (e.g. "0,0,0,6,-2" produces a 2mm dash and a 6mm space...why?).
    -Dashes smaller than 8.383mm can be used in drafting type fill patterns but that doesn't help as my pattern needs to be aligned to elements, have an adjustable origin and be visible in 3D views.

    Any suggestions???

    Maybe, if you can live with thick lines you could do squares laid on top of each other, but rotated. That might give you a thick circle.

      That panel has 3200 small holes so a fill will have 3200*N + 2 elements if N is the number of elements used to draw each. Octagons would require a fill containing 25602 elements which is a very heavy pattern for any model.

      I think you would convey an adequate representation by using small crosses for all holes and a short dash for all slots with origins adjusted to allow for any noticed auto-extension of very short lines.
