I am either missing a step, or there is an add-on to enable dimensioning, which I am unaware of.
There is a small "window" in the top toolbar named Distance, and there is a 1 in it, but it doesn't change.ĭimensioning is fundamental to my interest in LibreCAD, and I would appreciate help in solving this.
If I move the crosshair up (no click), vertical lines are extended from the top left and right corners of the rectangle, but no number (dimension) is displayed on the drawing surface or any of the panels to the right or below. I then move the crosshair over to the top right corner and left click once. I click on Dimension>Horizontal, then move the crosshair to the top left corner of the rectangle and left click once. So if you want to change line width directly, select the entities and go to Tools - Modify - Attributes and make your setting. I have tried to duplicate your problem in my drawing in LibreCAD and havent been able to do it. Also check to make sure your restrict horizontal icon on the top icon menu is not on. In the Properties palette, locate the 'Line Width' option. Go to the Properties toolbar or use the shortcut key P to open the Properties palette. Select the line or object whose width you want to change. Also check edit>current drawing preferences>dimensions and make sure the text height is 2.5. To change line widths in LibreCAD, follow these steps: 1.
There is only one layer, and the eye is on in the layer list panel on the right. Changing the color, width, and line type in graphics and visualizations serves various purposes, including improving readability, emphasizing important infor. There are two ways to define line width: directly when drawing by selecting in the pen tab, or if in the pen tab 'by layer' is set, via layer attributes. Re: How to Dimension a Line Hi Jetsetsam. Unfortunately, I have hit a roadblock in my first attempts at dimensioning a line.įollowing instructions in Bob's new manual, I have created a rectangle and saved it. It's not clear to me if there's a way to store some sort of additional data in FreeCAD that would assign a specified width to each line and use it when rendering the line (and when writing it back out to DXF).I have no experience with AutoCAD, but wish to become proficient at LibreCAD. So the DXF importer can fake line width by creating polygons instead of lines, but when this is re-exported, that's what's going into the file: polygons, not lines with a width. But as far as I am aware, FreeCAD doesn't have this idea of a line with a width: lines are simply lines in the mathematical sense, and are rendered with whatever width the user has configured in their overall display preferences. The DXF standard allows "thickness" to be specified for all components, from lines to vertices. Lines showing cut massive objects like walls maybe 0.5 mm. Maybe someone more familiar with the process can make sure I'm understanding correctly: A standard line width for a normal line is 0.25 mm. I took a closer look at this tonight, and actually as far as I can determine it's not possible for FreeCAD as it currently exists to import a DXF with line width information and to then re-export lines with that width.
Sorry, this may not be relevant but I just wanted to make sure i mentioned this so efforts won't be duplicated, as this was something you also mentioned above. Perhaps circumventing the need to use OCC at all to render TD stuff. Perhaps ot would be good to discuss any ideas about this with him since this is something he wants to tackle. I think that some of it relies on some OCC kernel that makes it very difficult to use. Thanks said something about Techdraw during his talk. There is some code in there that is trying to render it (though it doesn't seem the have an effect for me, or it's a very small one), but line thickness doesn't look like it's being output at all, or rather, is being written as a single hardcoded value. Master the art of adjusting line thickness t. I don't know if anyone is working on that project, but that's probably what needs to happen to support line thickness. Learn how to change line thickness in LibreCAD, a popular open-source CAD program, with this step-by-step guide. (tips for drawing a specific length of a line type the BOLD one into command-line). In looking at the code, the DXF output from TechDraw is still using the old Drawing code: there is a "TODO" note in there about replacing it.
