AutoCAD Application

I need an ObjectARX program: * To check the standards of a CAD file against predefined standards and report errors. This requirement is similar to the AutoCAD standards checker but with additional capabilities (example: Have to check and verify the spacing between two text items) * To create multileader type leaders based on specific criteria and with customizable baseline size, baseline position and spacing between baseline and text (you can code a standalone ALISP program for this if there is difficulty implementing it in ObjectARX) * To automate creation of a pdf file in the layout tab in "Window" mode using specific coordinates (if possible) I presently have nothing and you will have to start from scratch The program should work in the vanilla AutoCAD versions 2006 and above. You should have experience in writing ObjectARX applications for AutoCAD Timeframe for delivery: 4 weeks
