We know that Mario is looking for the princess. We also know that she will be in another castle for a long time. But still, Mario does not give up searching for her and for almost 30 years, we do not give up trying to help him

A slope describes the steepness of a line. It is also known as gradient. The slope or gradient of a straight line can be calculated when  points (Level 1) and (Level 2) are given. In this calculator, you can find the slope and equation of the straight line with two given points (two point slope form).

 Two commands, to convert in both directions between a Circle and a circular (two-equal-arc-segment closed) Polyline, such as the Donut command makes.  Both commands: 1. ask User to select again if they miss, pick an incorrect object type, or pick an object on a locked Layer; 2. remove selected/converted object, but can easily be edited to retain it; 3. account for different Coordinate Systems; 4. retain non-default/non-Bylayer color, linetype, linetype scale, lineweight, and/or thickness.

"I like to clean up each and every AutoCAD drawing to reduce file size and make the files more healthy using these commands: Audit: This command will examine the drawing file, find errors, and allow you to fix them. Purge: This command will allow you to purge any unused styles, blocks, etc. Be certain that you — or your coworker — won’t need them later. When in doubt, don’t purge it out. -Purge: This is the Command line–only version of the Purge command; it's used in customized LISP and scripts. Overkill: This awesome and aptly named command looks for things like duplicated lines on top of lines and removes them. I do this before sending the DWG to anyone, before creating the PDF file, and before my final save." Using This LISP You Can Clean Your AutoCAD Drawings
