Extensive Rail Industry experience enables us to provide compatible DWG to DGN CAD file conversion
What is a DWG to DGN CAD File conversion?
Many companies produce their drawings such as Electrical Layouts, Component Drawings & Schematics in AutoCad from Autodesk.
However, certain industries have specific standards in regards to CAD file types to be used. The Rail Industry in the Australia which includes Network Rail and LUL (London Underground Limited) use Bentley Microstation as their standard CAD Software.
Therefore, more often than not, suppliers have to provide their drawing in Microstation file format, which is DGN.
AutoCad have in the recent years added an export function within the Software which enables the user to Export to DGN.
Also, Bentley Microstation can open DWG files and save as DGN files.
Based on this, there should be no problem then.
Well it is all not that simple when you need to adhere to CAD Standards set out by Network Rail or LUL.
The files need to be referenced in a certain way (Xref for AutoCad) and also there should be specific levels used (layers for AutoCad).
How We can assist with DWG to DGN Conversion?
We fully understand the CAD Standards set out by Network Rail as well as London Underground.
Usually the drawing that require a CAD Conversion are 2D Drawings of Electrical or Mechanical Layouts, Component Drawings or Schematics.
First of, we would obtain the relevant CAD Standard and if possible establish contact person within Network Rail or LUL who we can work with. As these project are often multiple drawings. We have worked on projects from converting 10 drawings to +1000.
Usually the following work can be required.
1. Clean out existing DWG File (remove redundant layers, blocks etc.)
2. Assign new Levels within Microstation
3. Reference and fill out new Title block
4. Check all Reference Files
5. Check Model Origins
To assure the standards are kept we would work directly with Network Rail or LUL should this be of preference.
How much does a DWG to DGN CAD Conversion cost?
This entirely depends on the quality of the existing DWG files and far they differ from the required CAD Standard. We would usually produce a sample file which then get signed of. Based on that sample file we would establish an average per file price. We are used to carrying out small projects as well as conversion from +1000 files.
How secure are is our information with Australian Design & Drafting?
Especially for work such as CAD Conversion many companies might seek to outsource this work to countries such as India as this seems cheaper in the first instance.
We would like to add that we as a company policy do not Outsource our work. All our work is carried out in our Australian based offices with our own dedicated severs.
