Civil 3d Point Group by Description in Current dwg

Hi @jcoon,

Is this what you’re looking for?

Create a PointGroup by Descriptions

Hi I’m new to Dynamo, I’m trying to create a point group by similar descriptions. [image] for example I’d like to get all the SPTU in one point group and HDY points in another. I’ve been bumping my head with this for a day or so any help is welcomed Thanks Rich

@jcoon

Does anyone have a sample cogo point selection inside closed polyline

For this task, I can think of two methods:

1. Get the polycurve of the polyline
2. Get the COGO points as Dynamo points
3. Create a surface from the polycurve using Surface.ByPatch
4. Use Geometry.DoesIntersect to get boolean values of the COGO points that intersect the surface and those that don’t
5. Filter the original list of COGO points using List.FilterByBoolMask

OR

1. Get the COGO points as Dynamo points
2. Get the vertices of the polyline
3. Create a Dynamo polygon using Polygon.ByPoints with the polyline vertices
4. Use Polygon.ContainmentTest with the COGO points to get a list of booleans for the points that are within the polygon
5. Filter the original list of COGO points using List.FilterByBoolMask
