Linux for an engineer: September 2014
http://linuxforanengineer.blogspot.com/2014_09_01_archive.html
Linux for an engineer. Saturday, 13 September 2014. FreeCAD: simple Coin3d plot. Hi all: I'm back! Some time ago, when I was investigating about octrees and voxels to create a true CNC simulator, I played a bit with Coin3d, the scene graph render of FreeCAD. Coin3d is coded in C , but can be accesed with Python using Pivy. While I didn't find anything specially useful, I realized that one could easily plot math equations like this:. FreeCADGui.ActiveDocument.ActiveView.getSceneGraph() print. Update - Dou...

Linux for an engineer. Thursday, 28 August 2014. What's going on this summer. I'm having september exams, and that's the reason for not publishing anything remarkable this month. But that doesn't mean I've stopped doing FreeCAD stuff. This is what is currently going on:. A GCode generator for 2D CNC cutter. Is very experimental, but starts to show results. (green fast movement, red = given feed speed). Related with 2D CNC, I remodelled my crappy machine and did this:. Subscribe to: Posts (Atom). 160;Thou...

Linux for an engineer: FreeCAD: Sheet Metal Update 1
http://linuxforanengineer.blogspot.com/2015/05/freecad-sheet-metal-update-1.html
Linux for an engineer. Thursday, 14 May 2015. FreeCAD: Sheet Metal Update 1. After some time without touching FreeCAD, I have managed to go a bit further at the development of the sheet metal workbench. Although is not really a "workbench", but a set of scripts at the moment, most of the critical part is done: workflow, document structure, data tree. This video sums up the current possibilities:. Set up the workbench with icons. And a lot of small utilities like reliefs, slots, punching. Scanning 3d obje...

Linux for an engineer: FreeCAD: Drill macro
http://linuxforanengineer.blogspot.com/2015/07/freecad-drill-macro.html
Linux for an engineer. Saturday, 18 July 2015. I am working on a project that has a lot of drill operations. Being an "assembly", it can get quite tedious to create an sketch or part cylinder, place it and then do a boolean cut to make the drill. To speed it up, I have written a short macro that drills existing holes into the selected shapes:. Drill Macro JMG 2015 GPL Select a set of circles and then the shapes that you want to drill " ". Get user selection of edges. Retrieve object from selection list.

Linux for an engineer: April 2015
http://linuxforanengineer.blogspot.com/2015_04_01_archive.html
Linux for an engineer. Monday, 20 April 2015. FreeCAD: Sticker Sketch and Text. Sometimes you need to model a special part like a shift drum for a motorcycle gearbox or something more simple like putting text on your perfectly modelled cup of coffee. While the content of this post does not completely solve any of this problems, it shows an important step forward. I'm doing this because of its similarity with some parts of the sheet metal workbench core. Sin, cos, pi BaseCylinder =. Csa2, ssa2 *. L1projec...

Linux for an engineer. Thursday, 6 August 2015. FreeCAD: Double Slider Mechanism Animation. Since few days ago, this blog is two years old, and, also, last month it crossed the 4000 views/month barrier. I was thinking about a way of celebrating this events, and last night I saw a .gif image about a flat mechanism at which I could be staring the whole day:. I don't know its exact name, but "double slider mechanism" seems appropriate. It belongs to the family of flat, four bar linkage. Slider x placement =.

http://linuxforanengineer.blogspot.com/2015_06_01_archive.html
Linux for an engineer. Friday, 5 June 2015. FreeCAD: Sheet Metal Update 2. Some screenshots of the current state of the workbench:. My goal sheet metal part and what can be currently done with the workbench:. It took me less than 5 minutes to draw it (I cheated a bit and did not put any real measurements). It sums up the current capabilities. The object in the tree view:. You can also see the two orange icons, the only ones by now: "base fold" and "fold on edge". It seems not too different from Update 1.

Linux for an engineer. Thursday, 11 December 2014. FreeCAD: Sheet metal tool "Add Wall". Thought not seen here, I work in the sheet metal workbench from time to time ( last update. Being my greater effort coding the unfold algorithm ( related post. But I also work at the surrounding tools that this workbench needs, one of them is almost usable and is the reason of this post. The utility of the tool is explained with this video:. Code can be found here. How to use it:. Relief slots have two parameters:.
