![]() I have always wondered what "Length factor" might be useful for, except for special cases. Maybe also a different approach is in use. There you set your 1:5 scale, for example, and move your drawing around on the paper sheet, if you only want to depict a part of it, or just center it. The scaling down is then done in the printing process, in LibreCAD it is in the PrintPreview mode. The approach: In CAD you normally draw with the dimension the object really has, even if you intend a scaled down drawing. Thank you for considering to take a look at the issue. When I need to dimension a 1:5 part, I scale the drawing to 20% first, then set the dimension "Length Factor" to 5 (in Drawing Preferences -> Dimensions). I've been using LibreCAD for dimensioning small and medium sized parts for mechanical systems, usually a 1:1 to 1:5 scale on US Letter paper. I have a general question about your approach. This is probably within my ability to fix, I will take a look. I'm unfamiliar with architectural drafting style, but I trust you that this is a bug. Not a developer, just a newbies' questions answerer on the forum, Is there a good reason for this? Is it too difficult to implement? If it is within your scope could you have a look at that? The coming major release 2.2 would be a good moment to fix this. Just that stubborn "Fixed length" doesn't comply. So, for example, you can set the text height as 2.5 mm, which is the standard for an ordinary dimension, and it will always be printed out 2.5 mm high on paper, like in old times when you used a 2.5 mm stencil for that. If you want a drawing with the scale 1:100, you write "100" into there, and all the values for text, positions and arrow / tick sizes are multiplied by 100 for the screen appearance and print out. In the Drawings Preferences - Dimensions settings box you can tick "Fixed length" (Extension lines), that's used for architectural drawings.Īt the top of the box we have "General scale". It seems you are a specialist for dimensions. There's a bit more work to get it reviewable, but hopefully this will become one incremental pull request in a series to add full support for inside-horizontal to LibreCAD.Įl mié., 21 mar. ![]() ![]() My changes are currently in my github fork (below). There's still a fair amount of work to add full support for inside-horizontal, but I've made some decent progress so far for linear-type dimensions: I'm particularly interested in it because I just really like how it looks. McMaster-Carr technical drawings are all rendered with inside-horizontal style dimensions, metric or not. Inside-horizontal mode is toggled by the DXF group code $DIMTIH (Dimension Text Inside-Horizontal), and the style is generally more palatable for viewing drawings on stationary computer monitors. This shows the basic difference between inside-horizontal and aligned styles: LibreCAD uses aligned by default for all drawings, and for good reason: inside-horizontal is only partially implemented, and is pretty broken for linear dimensions. In AutoCAD, inside-horizontal is the default dimension text style for imperial drawings, whereas "aligned" is the default for metric drawings. I'm currently working on refactoring the code which draws dimensions, primarily to fix the appearance of "inside-horizontal" dimension text (aka. ![]()
