Unix Terminal Emulator Commands. Autocad Vba Join Polyline: Recipe Templates For Word Pad. We always seek to draw a balance between the preaching of the whole. Draw 2D Polyline, AutoCAD, VBA, Excel, Coordinates. A friend of mine, who is surveying engineer, asked me recently if it is possible to draw a polyline in AutoCAD using coordinates from an Excel file. To convert the polyline, select it and activate the To Arcs Polyline function.

I'm fairly new to vba so assume I've made a fundamantal error somewhere above. I'd really appreciate your input. By the way, ideally I'd also like to call out the vertex number relating to each coordinate grouping - I'm not sure if it's possibgle though - possibly something like Write #10, objAcad3DPoly.Vertex(lngL)? Cheers to anyone that can help.
