QR Codes, also called mobile barcodes, can represent plain text, URLs, contact information, or geographic coordinates (using the FIELD command). Any existing text objects can be converted to QR codes by setting the Optically Scannable (text) property to 'yes' in the Property palette.
This works well enough to create QR codes, but every once a QR code is in a drawing, it somehow breaks dimensions and leaders. When stretching the text for both leaders and dims disapears and is replaced with '...'. The original text or dimension reappears when the stretch or move command is finished, but it makes it really hard to locate Mleaders and dimensions in clean locations on drawings when you cannot see the size of the text you are trying to move.
I'm new to LISP in autocad. The code shown below draws circles (with radius of 1) in a sloped line. What I don't understand is the value of "a" does not increase in increments of 1. The center of the circle drawn in autocad is (1,1) , (1.7071,1.7071) , (3,3) , (3.7071,3.7071) , (5,5) ... Can someone pls. explain why?
Or, you can deactivate every osnap by setting the OSMODE system variable to 0 at the begining of the code and retore the previous value at the end (to be really safe, this method should need and error handler to insure the the previous value is reset in case an error occur during the code execution).
