![]() There are a couple of other editing options here. Now, we can click on okay to execute the changes into the raster file. See, it does kind of make it… It’s a little bit more neat. Let’s see what happens if we click on this image. Thicken lines just makes thinner lines more visible, and it kind of tries to smooth out these jagged edges like this one. In this case, this is a pretty clean image so there’s no need for us to use that. Remove speckles and holes to remove any visible graphic noise or holes that we can find in the image. Now, we have a couple of clean image options here. But if it is possible, always go for the option of clicking on threshold. You’ll see that if the image is already black and white, it’s going to be grayed out like this one, and it won’t be possible to click on it. ![]() In this case, the option isn’t available because the original image is already black and white. Now normally, you would want the click on threshold to turn the image black and white. So let’s clean up the image by clicking on clean image here in the upper left. In this case, you want to first clean this up, convert into a vector file and then save it as a DXF file. Let’s open up a sample floor plan raster file here. #LIBRECAD MOVE TO LAYER HOW TO#Today, I’m gonna be showing you how to use Scan2CAD to convert either raster or vector images into a DXF file format that you can open up on LibreCAD. With the raster files, you’ll have to trace over them to vectorize them, and when it comes to vector files, it can only really handle its native DXF vector file. ![]() #LIBRECAD MOVE TO LAYER SOFTWARE#In the above example a line thickness can applied to all entities on the “Walls” layer by changing the “Layer Settings” for that layer.LibreCAD is a nice piece of software but it gets kind of tricky when you try to import different image files into it. However, the attributes assigned by the layer can be overridden for entities if necessary. Every entity on that layer will adopt the attributes that have been assigned to that layer. Layers have an added advantage that all the pen attributes can be assigned to a layer. For example, all the walls in a floor plan drawing would be put on a layer named “Walls”. Typically entities with common functions or attributes are put on the same layer. While one layer can contain multiple entities, every entity in a drawing can only be associated with single layer. Layers could be added to show centre lines or dimensions on an engineering or manufacturing drawings, or to show different building systems on architectural drawings such as exterior walls, partitions, electrical, HVAC, grid lines, etc. Whether for engineering, architectural, construction, manufacturing or other types, layers were used to show different aspects on the drawing. These sheets were then overlaid one on top of another to produce final drawings. The layers were often drawn on separate transparent sheets of paper. #LIBRECAD MOVE TO LAYER MANUAL#Traditional manual drafting used a similar approach. Layers help organize drawings by allowing users to place and manage related entities. One of LibreCAD’s key features is the ability to use layers. A maximum of eight user defined colors can be added. User defined colors can be modified by right-clicking on a user defined color and selecting a new hue and value. User defined colors are created by clicking the Add button and then selecting the hue and value from the color selection tool. Selecting ”Custom” will allow a selection from a palette of 36 colors and shades of grey or from a user defined colors. If the block’s color is subsequently changed all entities in the block will be assigned the block’s color. When editing a block, selecting ”By Block” will assign the color that was defined for the block to the added entity. ![]() If the layer’s selected color is subsequently changed all entities on the layer will be assigned the layer’s color. Selecting ”By Layer” will assign the color that was defined for the layer (see above) to the entity. The drop-down menu allows the color to be selected ”By Layer”, ”By Block”, from the ”Custom” color selector, or chosen quickly from one of the 16 pre-defined colors: The color for an entity can be selected from the ”Color” selection drop-down menu. ![]()
