These are not asked frequently but “FAQ” seems like a good page title!
Q. How is the Windows XP version different from the normal version?
A. The XP version does not use 3D graphics acceleration to improve the quality of the graphics on screen. There are no other differences. The XP version is not old software and does not need to run in compatibility mode.
Q. Are there ways to measure forces, accelerations, and other physics stuff in the software?
A. No although it is possible to export the positions of connectors during the simulation of those connectors are set to draw their path.
A. No. There is no simulation of floppy mechanisms that rely on physics of any sort to run. There is no gravity. There are no springs. There is no way to have a sliding connection slip until a limit is reached before something is moved in the mechanism.
Q. I need help. I have a problem. It’s broken. What do I do?
A. Send me an email. My email address can be found in the software in the “About” box (click the little (i) icon in the upper right corner of the window).
Q. Can I get the source code?
A. Yes if you ask me about it and have a reason for getting the source code other than to sell my hard work for your own profit.
Q. Where is the Ratio button?
A. It was moved to the Align menu. The text below the dimensions text box just shows what type of information is in the box.
Q. Where is the Connect button? (And why does the “L” key not create sliding connections?)
A. The “Connect” feature has been changed to be the “Link” feature. Use the “Link” button to create a link from selected connectors. The “C” button still works because there’s no other use for it. The “L” button now creates links this way and is no longer the keyboard shortcut for creating sliding connections.
