LibreCAD is designed with emphasis on mouse-clicking input, and some options can be at the moment only selected by clicking, not by typing manuao command line. When the command line is active the “Command: So now when you press a key you are entering commands. You press the Escape key to leave the command line and another Escape to cancel what you have written on the command line.

It is possible to enter a partial command, like cir and press Tab to have the command completed to circle. If you type too short manua, segment of a command, such as c and press Tab, the command output will show “ch, a9cax, cut” because the command segment you typed in isn’t unique.

Many commands prompt you on the command line asking for further input. They tell you what input they expect – a point for example – and list other possibilities in the square bracket.

This means that the program is expecting a point from the command line or by clicking on drawing areaor you can select the Undo or Close option. You can do that by typing on the command line or by clicking on buttons on the context toolbar manuak Tool Options. When a9acd is some value already set and valid, for example when you use command offset, the current value is in sharp brackets, like a9ad So you see that value for offset is 5 and you can either set a new value by typing it into the command line or using the Tool Options toolbar or you can start drawing parallel entities.

Every command I describe below has a long format and a short format. For example the command for drawing a line has three formats: To use the two letter format li you do not have to activate the commandline. Just type li and LibreCAD displays the prompt. If you wish to continue drawing with just mouse input, you click on drawing to enter the point, or click on the tools palette to select the snap mode or whatever.

After selecting any desired snapping options on the main toolbar you can respond by clicking with the mouse on the drawing area to enter points. Or you can produce manula by entering into the command line:.

Produce points as described in the point section. After producing a line a9czd, any following points create a line segment with the point that precedes them. If there are at least two segments drawn, you can close the line draw a segment to the point where you started by entering close into the command line. To finish drawing lines you press [Esc]. All line segments created can be selected w9cad.

With Polyline all segments are considered a single object that can be selected with one click. LibreCad prompts you to with “Specify first point”. You draw polyline exactly as you would draw a line see above. The only difference is that all the segments of polyline are a single entity.


You can enter number from commandline or using Tool Options toolbar, you can select Through option. The default action is to click near an entity, indicating what side you wish to place the offset manial.

Offset works on lines, polylines but only on one segmentcircles, arcs, polygons but only on one segment.

Offset doesn’t work on ellipses, bezier curves here it kinda-sorta works but not the way you might expect. LibreCAD propmts you “Specify startpoint or [center]”. Here you can enter point for center, either by clicking on screen or by typing coordinates or type center and enter center. If you enter start point you are prompted to enter second and third point. LibreCAC draws an arc from the first point through the second point to the third one.

If you select “center” you are prompted to enter a center and then radius. After entering radius you are prompted for the starting point. Arcs drawn by center – radius – start point method always go counterclockwise from the start point.

LibreCAD propmts you “Specify center”. LibreCAC then prompts you for a radius. Please note than when you use toolbar, there are more possibilities for drawing a circle. Center and point, center and radius that you enter using tool options toolbartwo opposite points, three points LibreCAD draws a circle circumscribed to the triangel and finally Concentric option that is really just a parallel command in disguise.

LibreCAD propmts you “Specify first corner”. Here you can enter point for one of the acad of the rectangle, either by clicking on screen or by typing coordinates. LibreCAD then prompts you for an opposite corner.

You type the desired text to the multiline edit box. Above the edit box there are icons that will let you clear, copy or paste text, save text to file or load it from file. Under the edit box there are droplists to help you with entering symbols, such as diameter or unicode characters. After filling in the dialog box, you are presented with prompt “Specify insertion point”.

You specify a point using any of the above described ways. After entering the point, the text is inserted in place and you are prompted again to “Specify insertion point”. LibreCAD redraws the screen.

You can manyal this command, or appropriate mamual from the View toolbar to tell LibreCAD to redraw the screen. When zooming in and out around the drawing you will most probably use mainly mousewheel. Just point the cursor to the desired detail and scroll the mousewheel forward to zoom in.

Scroll the mousewheel backward to zoom out of the drawing.

This is different than using a mousewheel, because this zoom is always centered in the center of the screen. LibreCAD prompts you to specify the first edge and then the second edge. Then it displays the selected area on the entire drawing window. This is a very traditional way of viewing the drawing details dating many many years back to the times before Manul 10 manaul released. Nowadays it is often quicker and more comfortable to use mouse with a wheel and zoom in and out by using scrollwheel.

By pressing the scrollwheel or a middle button on mouse you can also pan around the drawing. LibreCAD sets the zoom factor so that you can see your entire drawing – all the entities.

LibreCAD sets the zoom factor so that you “undo” the last zoom. When zooming and panning around, the quickest and the most convenient way is to use the mousewheel. Just press it down and you can pan around the drawing in realtime.

This is very effective when combined with mousewheel zoom in and zoom out functionality. LibreCAD prompts you to click and drag to pan. This is a very traditional way of panning around the drawing dating many many years back to the times before AutoCAD 10 was released.

This command has the big disadvantage that after one grab and drag you are out of the command. So it is much more convenient to use x9cad with a wheel and pan with the wheel pressed down you can also zoom in and out by using scrollwheel.

At times when you have entered a command, zoomed the drawing, used the command line repetitively besides hitting the ESC key to exit out of the loaded commands you can run the kill command to clear the cache.

It does not seem to do anything but if you open up the command line window you will see it clear out all active commands. Most of the time you would not need to use this command but there are times when it seems like the app gets confused at what action to take, using the kill command clears out everything and cleans the slate.

I can’t figure out what this command does. Please edit this Wiki if you have any idea what it does. This is quicker and more convenient than using the next amnual commands.

LibreCAD reverts the last change you have made to the drawing. Unlike other programs AutoCAD the manua, command doesn’t revert the zoom and pan commands. LibreCAD cancels the last undo you have made. When you use the undo, it is easy to do one step too much undo. Using redo you can revert undo. This lets you go back and forth in the edit history.

LibreCad has tools that make drawing dimensions much easier. To modify the default dimensions you can change the preferences.

Click on the Drawing menu and select Current drawing preferences. A dialog panel will appear. In the preferences dialog panel select tab Dimensions. Here you can set:. LibreCAD propmts you “Specify first a9cav line a9cav. Here you can enter point for the first extension line origin, either by clicking on screen or by typing coordinates typically you use some snap to place the dimension exactly on the point you wish to dimension.

LibreCAC then prompts you for the second extension line origin. After specifying the second extension line origin you are propmted for dimesnion line location. Aligned dimension runs parallel to the line between the two extension line origins.

You use Aligned dimension when you need to indicate the length of the line that runs at the angle. You can also use it for horizontal or vertical lines, but for that you have specialized commands – see below.
