AutoCAD: Troubleshooting corrupt DWG files

-
Issue: 
An AutoCAD DWG file cannot be opened and causes AutoCAD to show error messages or alerts, or to freeze or crash.   

Causes: 
Possible causes of file corruption 
  • Network (transmission errors, file locking, latent writing of data)
  • Storage media degradation (bad sectors on a hard drive)
  • Defective or failing RAM
  • Operating system issues
  • Power surges
  • 3rd - party applications running inside the Autodesk product
  • DWGs created or saved by non-Autodesk non-RealDWG products
  • AutoCAD terminated while saving DWG (less frequent)

Recommendation: Audit and purge before saving

Solution: 
If a file cannot be opened, the following steps can be taken: 
  • RECOVER command 
  • Recovers a selected drawing file
  • If successful, open and run AUDIT command (Evaluates drawing integrity and possibly more error correction)
  • Set system variable AUDITCTL=1 to create a report of audit results
  • RECOVERALL command (Recovers a selected drawing file)
  • Attached and nested xrefs are also opened, repaired, resaved, and closed
  • INSERT and EXPLODE
  • Start a new DWG with no template 
  • Run INSERT and selected the corrupted drawing
  • Check the “Explode” option
  • If DGN data was used: 
  • NETLOAD the AutoCAD® DGN Hotfix (DgnLsPurge.dll) and run DGNPURGE
  • The Hotfix can be downloaded from the Autodesk® Knowledge Network Support 


If a file can be opened but still shows signs of corruption, the following steps can be taken:
  • RECOVER and AUDIT
  • PURGE command
  • Copy and Paste into a new drawing
  • AECTOACAD (-EXPORTTOAUTOCAD) 
  • Exports to a pure AutoCAD file in selected drawing version
  • Strips potentially corrupt custom objects
  • WBLOCK command 
  • Set all layers ON, THAWED and UNLOCKED
  • WBLOCK all objects in the drawing to an external block file
  • INSERT the resulting file as block into a new drawing (check the “Explode” option or EXPLODE the block after inserting)
  • AUDIT and PURGE
  • DXFOUT/DXFIN 
  • DXFOUT to create a new .dxf file
  • Start new drawing and DXFIN to import the new .dxf file
  • Also try exporting as AutoCAD 12 DXF
  • XREF into a new drawing and BIND

How to Save AutoCAD Drawing as Read Only

How to Save Auto-CAD  Drawing as Read Only – is quite a difficult way to answer. The only way to answer this question is by giving different options for the user to Save Auto-CAD Drawing as Read Only. Let’s see some of them below. Save Auto-CAD Drawing as Read Only Some of the different methods are listed below please choose which is appropriate in your case. Method 1 – Use Save As Auto-CAD Drawing Files as DXF (Drawing Interchange Format, or Drawing Exchange Format is a CAD data file format developed by Autodesk), by this method you actually prevent the user to make any changes to your drawing files. Making the Drawing as Read-Only Files Method 2 – Ideally you could right click on the drawing file icon (once saved), go to properties and tick read only. Ahh, well that doesn’t “lock” the drawing or anything. they can still edit it, do a Save As, or simply unchecked the Read Only option for the file once they have it. Method 3 – In case you are on a Network, you can requ

Revit Tip: How to Slope Horizontal Steel Beam

How to Slope Horizontal Steel Beam (with images) Issue: You have an existing beam that has a level as its work plane. You want to set its work plane to be a sloped reference plane, but only the reference planes or levels parallel to the beam are available when you edit the beam. Solution: To make the existing steel beam align with a sloped reference plane. Open an elevation or section view of the beam. Draw a reference plane parallel to the beam/slab using the Reference Plane tool on the Basics tab of the Design bar and name it by editing the reference plane properties. Select the beam. Click Edit Work Plane on the Options bar. Select Name and select the reference plane that you just created from the drop-down menu and then click OK. Draw a sloped reference plane using the Reference Plane tool and name it. Click Align to align the horizontal reference plane to the sloped reference plane. That's it. Bottom-line: After you made it, you ca

The Top 10 Best Things You Can Do In Revit

Use a project file standard template for your projects. This template can be an RVT file with worksets or an RTE file without worksets. Any custom and repetitive element showing more than one view on your sheets should be a 2d or 3d family. These elements take ups less memory space than in place families and are easier to manipulate and store in your Revit library for future projects. Always utilize the 4 steps process of creating families. (a. Create reference planes b. Dimension assign parameters and flex. c. Create extrusion, align lock to reference planes, d. Assign materials, visibility options and flex parameters). Use titleblock sheet templates with parameters. Draw details with details components and filled/masking regions to minimize loose linework and easier revising or editing. Open and audit projects weekly. Keep project file size under 200mb for maximum sync to central speed, reduced network latency and better file performance. Prepare your cad dwg file befor
