Emboss a stone-like pattern over a big face

[ricardo.peironcely]

I'm trying to use fusion360 to model a stone bridge for a railway model layout. 
I have a simple bridge structure and I want to emboss a stone like pattern on it. For it I've created one sketch with the tessellation, adding manually some errors, but when I try to repeat this with create > rectangular pattern, fusion360 hangs.

Seems that the sketch is too complicated,

Has somebody any idea about a workflow to do this?

Hi,

Patterns should always be created from features, not sketches. To do this, you could create 2 sketch features of the stone profile, extrude them and then generate the patterns from them.
Please upload a sample f3d file for demonstration

Hi,

In the screencast I show one way to reduce the pattern problem of sketches.
I created an elementary sketch for 3 extrusion profiles, then extruded them on an auxiliary body and created the stone pattern from these features with two rectangular patterns.
This pattern is then projected into a sketch and embossed onto the bridge wall.
