For me I get a lot of files from students for laser cutting, but first they need to be cleaned up. The attached file contains blocks and duplicates and cleaning this up in QCAD can take an absolute age, it can be done but it takes quite a while. For the everyday file created with QCAD there are little problems I must say...but when I get files like this that are created with other CAD programs, they do take some cleaning up.
@Andrew, is there a way of speeding up this process in QCAD? or maybe extra development is required to handle this type of big file?
Be prepared the file is very busy!
For the best support please state your operating system, QCAD version and add any supporting DXF/DWG files, screenshots etc...
