arrowed line (arrow marker symbol)

[PeterBennett]

Hello All,

Would someone please share a sample on how to make an arrowed line?

I would like to draw arrow heads on top of my polyline, not triangles.

Please advice

Thank you in advance

Hi,

Are the arrow heads to be positioned only at vertices or at a constant distance apart along the line?

If it's the former then you may be able to achieve the desired effect just with a CompositeSymbol. For a polyline geometry you can add both line-based and point-based symbols to the CompositeSymbol - the point-based symbols will just be applied to the vertices.

If you would line arrows at a constant distance apart along the length of the line then I think you'll need to consider using the more advanced CIM symbology spec. We do have a basic sample (Symbols and Labels | ArcGIS for Developers ) but as far as I know, the spec itself has so far only been published as part of the ArcGIS Pro API Reference e.g. ArcGIS Pro 1.1 API Reference Guide​.

Cheers

Mike

Hello,

Where can I find a detailed and valid documentation of the CIM symbology syntax? Is there an editor/plugin for an editor that supports writing this syntax?

Thank You!
