How to Lock scale of surface patterns?

[novelh]

I have a stone pattern on a wall but this pattern can not change scale because the stones need to be a certain size. Here is the problem. At 1:100 the scale looks fine but at 1:50 the stones look half the size. Normally this would be accurate for hatches but surface patterns show things such as siding and stone at a particular size. I have attached images for reference. How can you lock the scale of a surface pattern so it does not change size when you change scale?

Not got revit in front of me but pretty sure you can make 'model' patterns and 'surface' patterns, one of them doesn't change if I remember rightly

what Dave said...

 

it must be a drafting pattern which will be the same size when printed (changes on the model at different scales) where as model patterns are to scale in the model so will always measure off the right size no matter what scale it is at but will print differently depending on the scale of the view. Always use a model pattern if it is representing a surface material (brick, sheet joints etc) Drafting pattern are there for use in cut pattens or generic hatched areas.
