auto-create line around shape?

Recommended Posts

This is a big reach.  Is there any function in CA that would allow me to import an image (painted arrows on parking lots) and automatically create a boundary line  around the black fill?  That I could then fetch the area inside?  I need to place these on a site plan, but provide a painting area.  There may be no easy way to automatically perform this.  I can readily trace with cad lines and manually count, but there are quite a few more shapes in addition to these.

 

Thank you all.

There’s quite a few sites that have downloads for all kinds of street markings in cad format. Just import those into Chief?

Unfortunately, these sizes/shapes are specific to this client.  Ages ago I had a program that would attempt to create vector drawings from raster files (for old school importing USGS maps), but that's long gone.  Didn't know if CA would possibly have some trick similar to that.

If you convert those to PDF and then convert the PDF to DWG and import the DWG you will be able to get all the boundary lines.

 

Then convert the polyline to get a Road Marking.
