Hi everyone! I need help to write an application which would do the following: - compare 2 drawings on the 3rd one (yes, I'm familiar with COMPARE plug in from Autodesk,) - both drawings are 2D, railway design built from lines and arcs on different layers - the application should compare those 2 designs and give as output: if the design is partly this same (no displacement) - grey line/arc. - if the shift/ displacement between 2 designs is less than 10cm - green line/circle - if the shift is equal or more than 10cm (=>) - red - the part of design that is =>10 cm on the 1st drawing - make black with dotted line (line type:HIDDEN 5), what means that this part has to be demolished. I paste drawing for general overview. drawing 03-08-2017.pdf I hope is clear - otherwise please ask me for better explanation HOW I DID IT TILL NOW? I copied the 2 drawings into the 3rd one, with this same scale, units, etc. I used commando OFFSET and value 10cm Everything what was above- I made red, what was under - made green, and the lines which were overlapping- grey. Disadvantages : - you have to check km of lines - you have to use BREAK A POINT every time lines crosses my 10cm offset Any ideas?

Hi guys, Bit of a strange request. I'm looking for something that will shift a selection of polygon vertices by a random amount for each vertex. In a perfect world I'd love to set a tolerance of say 5cm and have the vertices move in any x,y direction by random amounts up to 5cm. Any ideas would be appreciated. Cheers Dave

When trying to orbit while pressing the mouse wheel & holding shift nothing happens. I have looked into CUI and everything is set up correctly under mouse buttons. Clicking on the navigation wheel allows me to orbit but using shift and mouse is so much quicker. I have just upgraded to AutoCAD 2013 perhaps that is the problem?? How can I fix this?? Cheers

I'm running Autocad 2011 on MAC (dont ask why, its just needs to be done..) and now I'm struggling getting all my old keyboard shortcuts from PC setup up again. Does anyone know how to include the SHIFT key when editing/customizing the command aliases?? ie, i want SHIFT+V to = MOVE So in the Command Alias text file, Im guessing it should look something like this? SHIFT+V, *MOVE But that doesnt work. I really really want to stick with this format, and not need to include other control keys, ie CTRL+SHIFT. Any info or help would be great! Cheers, Matt
