Hey Gizem,
First, ask yourself, is the shape flat and closed? No overlapping boundary curves, etc.
Also consider scale. Make sure your shape and the units of the file all make sense with the parameters of the pavers in the Workflow. The Paving Workflow is built for feet for now. (We are in the process of making these adaptive to meters, starting with the Topo Workflow).
Hi Chris and co,
I am running a pipeline planar surface into the area module, into the paving pattern module. No matter what tolerances I set on the area module, there will be instances where whole pavers are placed outside the surface extent. I am not using the paver trim module, as I was hoping for whole pavers to approximate the boundary in a pixelated, jaggered fashion.
Am I doing something incorrect here? Is there a way of changing the tolerance, say if the centrepoint of the paver polygon was on the surface itself, it would determine if it was kept or not?
I’m still learning grasshopper, so I hope this is easy enough to follow.
Thanks,
Hi Nathan,
I cannot tell from the image of your script, but do you have the Add Pattern to Area component plugged into the Trim Paving Areas component?
This would be the crucial missing step to be able to trim your pavers to the edge of your paving area.

Hi Ben,
I’m not using the Trim Paving Areas component. I trialled this component, but it would make a ‘hard trim’ to the cutting boundary, whereas I would like to use whole pavers to approximate a boundary (ie, a staggered stepped paving edge around ‘curved’ boundaries, like in the screenshot above).
My issue lies in the Add Pattern to Area component covering far beyond the planar surface boundary - in the second screenshot for example, whole paver units are created off the planar surface. I was hoping there would be a way to tighten this tolerance - that a curve MUST touch the planar surface for it to be shown.
Hi Nathan,
This approach may require a bit of Grasshopper work. The trim pavers to area component is really meant to create that hard line edge at your paving area and not necessarily the type of staggered edge you are looking for.
The easiest way to approach this is probably to use the Trim Pavers to Area component to obtain all the paver curves inside the paving area and then use Grasshopper to identify which paver curves of all the rest of the pavers intersect the paving area and isolate them. You could then recombine all the paver curve outputs and feed them back through the Custom Pavers component to begin applying a color rule.
You could offset your paving area borders before filling.
We provide that extra bit around the edge to ensure that the pattern covers the area.
