What is DWGeditor. What is difference between DWGeditor, SolidWorks and e-drawing. Thank you

Re: DWGeditor

I'm not the right person to provide a definitive answer to this, so hopefully someone else will be able to contribute. SolidWorks is a 3D mechanical CAD system, allowing you to parametrically design complex parts and assemblies in 3D - COSMOSFloworks operates inside SolidWorks to compute flow and heat transfer in and around the solid geometry.

I suspect that DWGeditor and e-drawing are tools that allow you to view a finished 3D model - what SolidWorks produces, so that the model can be shared with other members of the design team. They would not be able to change the model, or only make very limited changes. Hope that helps.

If you are a student you may very well have access to SolidWorks at your college/university.

Re: DWGeditor
Hi John

Yes I am a student and I have access to SolidWorks in my University. When I installed SolidWorks (i think its academic version) it also generated DWGeditor and e-drawing so I was wondering that they were for.

Is it possible to generate a mesh in SolidWorks and then export it to OpenFOAM? Is it possible to create different parts in a geometry to set boundary conditions?

Re: DWGeditor
I don't know of a way to create a mesh in SolidWorks and export it. You might want to take a look at COSMOSWorks and see if that has the ability to create and export a mesh. COSMOSFloworks uses an octree mesh but this is not exportable. Depending on what you want to do you may find COSMOSFloworks easier to use as it gets around this problem.

If you have an educational license of SolidWorks you should have access to Floworks. To find out how to check see my earlier post:

Good luck.

While this question is really not appropriate for this forum, I think that I can answer it for you.

DWGeditor functionality enables you to edit and create native DWG files in a familiar user interface, so that you don't have to maintain a seat of AutoCAD when choosing to use SolidWorks as your primary 3D design software tool.

More info from the website:

DWGeditor uses native DWG files DWGeditor is compatible with AutoCAD file versions 2.5 to the latest release DWGeditor has a familiar user interface for AutoCAD users DWGeditor is provided and maintained as part of SolidWorks design software SolidWorks customers receive 3 licenses of DWGeditor for every license of SolidWorks on subscription support *********

You may also want to check out DWGgateway at DWGgateway is simple, it allows one to:
:Open DWG files created by any version of AutoCAD software.
:Save DWG files to any version of AutoCAD software.
:No need to leave the AutoCAD UI to open, save, or convert files - simply access DWGgateway from inside AutoCAD. *********

>>Is it possible to generate a mesh in SolidWorks and then export it to OpenFOAM? Is it possible to create different parts in a geometry to set boundary conditions?<<

You can create a mesh in the EDU version of SolidWorks, because it automatically includes a version of the COSMOSWorks analysis software. You can also apply boundary conditions to any part in an assembly and additionally define how those parts interact with one another by definig a contact group.

In the commercial version, you can export the COSMOSWorks studies, including the mesh, material props. and BC's, to either a GeoSTAR, ANSYS, NASTRAN, PATRAN or Abaqus file, but I am not sure about the EDU version. I am not very familiar with OpenFOAM, but it should be able to read in one of these formats. If not directly, I would suggest exporting the file to one of those formats, say GeoSTAR, and editing in a text editor, like Notepad++, the commands to get the locations of all the nodes and the element connectivities. The OpenFOAM preprocessor should be able to read in the data like that.

A better question is: If you have the ability to run COSMOSFloWorks from the EDU version, why do you need to run OpenFOAM?

changing to millimeters
I was woundering how to change the drawing setting from decimal to millimeters? Is there another way to change it, besides throw print set up.

Re: DWGeditor
SolidWorks is A 3D-Mechanical automation software.DWGEditor is a 2d software just sane as autocad and Edrawing is used to publish any model, drawing,and send to any other where solidworks is not installed. but all these products come under one brand SolidWorks.
