An attribute is a label or tag that contains information.

Block Attributesīlocks can also contain Attributes. Each entity could be on any layer and could have different colour, line weight and line type properties. Lines, arcs, circles, text or even other blocks. If you edit a block you are editing the block definition and all instances of that block will change.Ī block definition can contain any number and any kind of entities i.e. You can access the block definition via any instance of that block. The block definition is stored in the magical ether of your drawing file. A copy of a block is know as an ‘instance’ of a block definition. A block ‘ Definition’ and a block ‘ Instance’. Unlike groups you cannot change the geometry in one block without changing all the copies of that block.* Block Definitions and InstancesĪutoCAD Blocks have two parts. Unlike AutoCAD’s Groups If you change the geometry that is contained within a block all copies of that block will also update. Try the Another DXF Importer plugin to see if that makes a difference - sometimes it works better than the native dwg importer, sometimes worse.AutoCAD blocks are a way of collecting geometry together into one object which you can use repeatedly in your drawings.Maybe explode blocks and bind all xrefs before importing to QGIS. If so, may need to do something to the original dwg to get them all into the right place. Try going into the attribute table for your I-LAB-FURN lines and right click on a row and zoom to feature - see if it's ended up somewhere else.Go to your QGIS Project Properties and change the background colour of your project to grey or black to see if anything shows up - the missing lines might be white in colour.Here are some general troubleshooting ideas: Sometimes the coordinates will end up all over the place because of xrefs and so on. Sometimes when a block is imported that way it retains the original colour feature (so you may have some white coloured lines). Sometimes features that appear to be in a specific layer in CAD will end up on another layer because the block itself is on that other layer. A lot depends on how the original dwg was set up.
