(= relative to the last position at an angle of 10 degrees at a given length of 10 units long). * Polar coordinates can be either absolute or relative, the < sign is used to represent an angle - e.g. * The method that tesco is talking about is currently not available in LibreCAD yet! The only method of achieving this at the moment is by either using the 'Horizontal lines' tool (by entering values into the 'Length' field') or as Claude suggests - by entering either absolute 10,10 (= 10 units in X direction, 10 units in Y direction from absolute origin 0,0) or relative (= 10 units in x and y direction 'relative' from the last position!) 'Horizontal Lines' or 'Circle with center and radius' - automatically you will be offered different options (length, radius etc.) where you can enter values in fields.

The tab above the drawing screen will change and offer fields to set angle and factor at insertion, choose insertion point and insert. Im not able to change the line width of an existing line through the Tools/Modify/Properties dialog. No, there is no drag and drop from the library to the drawing, you have to click on the symbol, and then on "Insert", below. I have included 2 templates in 1:1 and 1:100 you can try out. This is an interim release of the of the LibreCAD User Manual and is subject to change. I recommend to draw a rectangle in the size of the intended print paper first (adapted to intended print scale), to get a feeling of sizes of your elements on the sheet when drawing. You may have to change the size factor when importing elements from your library. Or if you want to draw the electrical installations of a house into a floor plan you might need 1:100. If you are drawing an electrical diagram there isn't really a scale to apply, so probably you will use 1:1. Is there a way of increasing the line width above 2.11mm. If you have the 0 layer selected and then check the box the entity selected will not change to that layer until you click on the 0 layer. If I look at the attributes for one line, it says the line width is 'By Layer'. If you want to change multiple items you have to activate Edit -> Application Preferences -> Default Tab check box 'Modify layer of selected entities, at layer activation. The problem seems to be lying in the initial drawing layout. I want to find the default line width do I can change it for the whole drawing.

If you want the lines thinner you would have to set a scale of maybe 10:1, upscaling, which is unusual. In the latter case for example you can change the colour of all the entities on the 'axes' layer by setting the colour (red for example) for that layer. Each entity can have its own attributes or have its attributes defined by the layer it is placed on. If you enter start point you are prompted to enter second and third point. Layers can have their own attributes also (colour, line width, line style etc.). A4 is 297 x 210 mm so if we make the 5000 mm be shown as a 250 mm long line wed be set. Here you can enter point for center, either by clicking on screen or by typing coordinates or type center and enter center. It introduces quite a few LibreCAD concepts, and links to other pages that explain these. In print preview with a scale set at 1:1 it will look like in drawing mode, but with scale set at 1:10 or 1:100 lines will look fatter in relation to the drawing contents, as lines will be printed in their fixed width, whereas the geometry will be scaled down. LibreCAD propmts you 'Specify startpoint or center'. Lines showing cut massive objects like walls maybe 0.5 mm. ![]() In drawing mode line width always looks like when printed at scale 1:1. A standard line width for a normal line is 0.25 mm. (Units can be inches, feet, meters, millimeter or whatever.) For CAD it is essential that you understand Cartesian, polar and relative coordinates. ![]() 25.24,10.99 would create a rectangle that is exactly 25.24 units wide and 10.99 units tall. ![]() If your circles look like donuts in drawing mode, they are very small in comparison to the line width, for instance 2mm diameter at a line width of 0.5mm. To make a rectangle to a specific and precise size enter the relative coordinate in the command line.
