Cropviews by area region

Hi there!, my name is Miguel from Spain and I have been working on a Dynamo Routine which I could not be able to solve yet… hope you can help me.

Basically I have Rent Areas (Áreas de Alquiler) which I want to get its boundaries to use them a crop regions for views in Dynamo.
It was easy but the thing is I have created complex lines as nurbs, arcs, etc. to use them as a crop regions.

I tried to transform them in straight lines by segments and aplly it to views with no success.

The node you need is called something like Curve.ApproximateWithLinesAndArcSegments. I usually find it by searching for ‘approximate’ as the actual name is too long. The resulting set of curves can be joined into one PolyCurve which can be offset as needed (typically I find a little bit of context helps).

I solved it creating filled regions… somehow the cropregions does not accept nurbs, curves or similar “complex” geometry.

I tried to upload the code and dynamo noddes but I am a newbie and the forum do not allow that yet… thanks for the advice!!
