Why? Because these lines will consist of one contiguous segment on one layer. Continuous linetypes are vastly more user friendly than DGN linetypes in CAD. Running the Nuke tool on a drawing will turn most of your linetypes to Continuous. It also brought the file size down to a much more manageable 140 KB. The Nuke tool purged the drawing of all these unnecessary performance-sabotaging items. The file's size was a result of the glut of proxy objects and DGN linetypes it originally contained. The original drawing file in our example took up a whopping 15.2 MB of space – an enormous file whose size will inevitably cause it to load slowly. As a result, the file size decreased significantly. In this example, we closed the drawing in question and ran the nuke tool. In this case, the drawing file will likely be overcrowded with DGN linetypes and other unnecessary junk, giving it an excessively large file size. In the example shown below, the drawing has an excessive number of proxy objects in the form of DGN linetypes – 112,476, to be exact. This dialog box shows the number of proxy objects contained in your drawing.

When you have this option selected, the Proxy Information dialog box will open each time you open a drawing. For more information, visit our documentation section on the CAD Options settings, Open and Save Tab. We recommend going to your CAD Options and checking the setting to Show the Proxy Information dialog box. If you need to preserve the Layout tabs in your drawing, you may need to clean your drawing manually. Follow our drawing cleanup steps.īecause we designed the Nuke tool for use with drawings received from consultants where the actual drawing file is most important, running the Nuke tool will remove layout tabs from your drawing. If you're having these types of issues when working on a CalTrans project, see our article on resolving issues with CalTrans linetypes.ĭrawing cleanup is especially important for drawings that were created in MicroStation. These issues can result from the DGN linetypes CalTrans requires in designs. Issues with California Department of Transportation (CalTrans) Linetypesĭesigners of projects created for, or in conjunction with, CalTrans have reported having excessive file sizes, as well as issues with fonts and Xrefs. If you get into the habit of cleaning any drawing you receive from an outside source, you'll nip several of these issues in the bud. In fact, the discord between AutoCAD and MicroStation is one of the main reasons we developed the Nuke tool.

It's a basic compatibility issue between the two software platforms. This in turn will not only make your drawing difficult to work with – it will also contribute to an enormous file size. As a result, any linework that originated as DGN will consist of fragmented segments rather than continuous lines. These blocks will then be reused throughout the drawing. In many cases, when you open a CAD drawing that contains DGN linetypes, CAD will assign an anonymous block to each segment or tick in the line. When you open a drawing in CAD without cleaning it, any DGN linework in that drawing will show up in the drawing with DGN linetypes assigned to it.ĬAD really doesn't like DGN linetypes. "DGN linetypes" refers to linework created in MicroStation.

So what are DGN linetypes, why are they a problem in CAD, and how does cleaning your drawing correct the problems caused by DGN linetypes? Besides eliminating proxy objects and reducing unnecessarily large drawing file sizes, drawing cleanup – especially when performed with the Nuke tool – alleviates a number of issues inherent in DGN linetypes. We can never overemphasize the importance of "cleaning" any drawing you receive from a colleague, consultant, or client. Issues with California Department of Transportation (CalTrans) Linetypes.
