Hello, I have been trying for the last few days to automate out a process but have found myself pretty stuck. The process now involves manually going in and looking at the properties of the polyline and copying over the length to a separate excel file and matching it to the block that it goes to. The blocks all have their locations recorded on a separate excel file. The best lead that I have right now is that I can use Data Extraction to pull all of the poly line data at once. However sadly the Data Extraction command cannot pull information of the vertexes of polylines. This is where i need help! I was thinking that I could get around this by assigning the location of the first vertex of the polyline's (the start point 's) X and Y coordinates to the hyperlink, which CAN be extracted with Data Extraction. With the X and Y coordinates I would be able to cross compare the X and Y coordinates with the one from the block and know which it is matched too. I am very new to using LISP and have attempted to write it myself with little success. I am not sure how to write in the Hyperlink just as a string rather than as an actual address. I would like to be able to select all of the polylines at once and have to command change all the hyperlinks at once. Thanks in advance for the help, I am exited to get better at using LISP! Leo

Hello, I recently discovered the potential in acad with lisps, and first of all I want to thank all the people sharing their knowledge (specific thanks to Tharwat and GC gile)! I am completely ignorant regarding what seems like programming here, but I am very willing to try and learn (allready succeeded in changing a parameter in a lisp all by myself!) The facts are: I have lots of closed 2d polylines (or lwpolylines, doesn't really matter because I have learned how to turn my polys into lwpolys). I have to extract their area, layer and coordinates, in a way that each polyline's data can be identified in the resulting file. I started by researching a way to automatically name the polylines, not much luck, so I am determined to enter numbers manually in the hyperlink field for each polyline. I have also found a lisp that extracts hyperlink, layer and area for multiple polys at once, which is a great first step (as a newbie I am not sure if I can post the link here). What now remains is to extract each poly’s coordinates together with its hyperlink. Do you think it is doable to invent a routine and achieve this for many polylines at once? Alternatively I will have to list and copy paste the coords for each polyline separately... for 400 polylines ... and then again in another similar dwg... etc. Sorry for the large thread, I hope I explained properly – and sorry if the answer already exists somewhere, I did my best to find it but didn’t (I did find quite some lisps to export coords, without separation per polyline and without hyperlink. Maybe someone experienced could alter these to include the extra data, but this is not my case…) Many thanks in advance to all the helpfull inlightened people here, Maria
