I was trying to make a tutorial for the Linkage software to show how to design a vertical sliding garage door. The door is built out of four or five segments with rollers at the intersections. The rollers roll in tracks that are vertical then transition through a…
Continue readingThe image above shows the current state of the Linkage app for the Mac. There is a main editor window and a sidebar with two panels. The visible panel is the “properties” panel. The other panel is the element selection panel where elements can be selected and deselected…
Continue readingI read a while back about how linked lists were not included in the standard Swift library because they are something that only gets used in classroom situations where people are learning about algorithms., or some such nonsense (in my humble opinion). But then I did a test…
Continue readingI’m working on the Mac version of the Linkage app and I’ve been having some trouble with panning and zooming. When a single finger is slide along the top of the Apple Magic Mouse, the software gets a “scrollWheel” event. It’s a Magic Mouse so there are values…
Continue readingHave you used the Linkage software? Was it useful but you didn’t think it was worth it to send me a pile of money? Please consider a simple $1 donation on Patreon (https://www.patreon.com/rectorsquid). It won’t add up to more than $12 per year but it will still be…
Continue readingI had some C++ code that would determine if any element in a list was selected. A “selected” element is one that has a boolean variable “isSelected” set to be true: bool bLinkSelected = false; POSITION Position = pConnector->GetLinkList()->GetHeadPosition(); while( Position != 0 ) { CLink* pLink =…
Continue readingA Linkage document file contains coordinates based on there being 96.0 pixels per inch. If the software is rendering onto an old monitor then the document units are scaled based on the amount of zoom in effect and then they are translated to different coordinates if the document…
Continue readingI am porting the Linkage program to the Mac in Swift, as I’ve mentioned in other posts. I’m trying to be “Swifty” because a language should be taken advantage of and because I like to learn new programming paradigms (or simply styles since this might not be a…
Continue readingIn the image above, there is a complexity that cannot be handled by the Linkage simulator. Although it might not look complicated, the lack of kinematic chain simulation in the software makes this impossible to simulate. The Linkage software, as I have written about on numerous occasions, uses…
Continue readingI’ve started porting the Linkage software to the Macintosh (“Mac” for those of you who have never heard it called by its “real” name). So far, the only problems I’ve had are those related to the design being done wrong; The language changes are insignificant since I program…
