Walls Saved As DXF Lost
Read 614 times

I have been trying to back up my important turbocad drawings by saving as dxf. But they contain walls and other architectural parts (windows, doors) and none of these architectural components appear when I use a dxf viewer to see the saved files.

Why do walls and related parts not show up in the dxf files? They do when saved and then viewed as dwg files but these files are twice the size and so not great for backups.

What version of TC are you using + type ??
Just tested in v 2017 Platinum and i did not have any problems with any architectual parts.

Thanks for help Torfinn.

My version: 2015 Platinum Pro

Do you still have that version to test on?

Just did a quick test and not seeing the same as you are finding with regards to approximate file sizes,  .tcw file = 5Mb,  .dwg = 7.2Mb,   .dxf = 12.5Mb,  therefore in my test saving as dxf produces far greater file sizes.

with regards saving dxf from 2015, it saved ok (walls, 37 doors and 55 windows) and displayed in Autodesk Trueview, though once saved as dxf they are no longer recognised as TCwindows etc,  just mesh objects when the dxf is loaded in TC 2017.

Thank you Andy H. It would seem then that although my dwg saves are much larger, that is the way I must go with these particular files and with running TC2015. Here are typical files sizes for the same drawing (MB):

tcw: 1.19 dxf: 3.22; dwg: 10.65

Perhaps it's the kinds of elements that are in my drawings that make for the size ratios so much different from yours. There are several stock library items in them such as a stove, and a washer & dryer - all 3D objects.

Again, thanks for your help Torfinn and Andy H.

I find similar about size, TC = 17 MB, dfx = 27.5 and dwg was 59 mb
2017 file saved as 2015 opens ok in 2015, save as dxf also was ok, but the "funny" part, when switching to 2015 GDI mode and then to dxf, True Viewer just freeze and i had to exit it by task manager :)

Yes, Torfinn, I also find that GDI / RedSDK switches are big time trouble for windows and turbocad. I try with my current work, mostly electrical floor plans, that it's best to stick with GDI as trying to open dwg or dxf files from other sources often just come out as total black outs if in RedSDK mode; usually they open fine in GDI mode.

One more thing, can you guys please have a look at how messed up the dxf file saves are? The walls are just a mess. I will attach or insert pdf images of the TCW (good) and DXF (messed up) drawings.

Oh, also, how to insert  and image in this post? I get the "|img|whatsinhere??|/img|" button part. But what to put inside the brackets?

I believe it is up to the way Andy was talking about, it comes back as a Surface and what you see is all the triangles that the wall's are in basic, but have you checked that you are in Native/ Native mode, i can very easy get this kind of lines if i switch to LW or Open GL/ Native.

Just below the area here where you write click on the "Attachment and other options" and it will expand and you can the browse to your file, look at the bottom about file size and type's.

Autodesk perpetually licensed ACIS V7, which is why .dwg retains solids, at the potential expense of a file size hit, but if you use high-poly
 stock pieces imported in .3ds or some other facet format, the vertex coordinate cost of those can outweigh that.

Instead of trying to insert an image, just attach it.  Click on the Attachments and other options button to display them, then Attach the image by clicking on Browse.

My understanding is that Architectural objects are not handled in AutoCAD and that you have to get Revit to use them.

I think they do save in dwg format so that they are compatible with autocad architecture.

Thank you nikkipollard, Jeffin90620, murray dickinson and Torfinn for further replies and your good help!

nikkipollard: Yes, the dwg save for the same file that is messed up as dxf I can open again in TC 2015 and the walls are still walls and everything looks right. Further, my tiny CAD viewer app displays everything nicely as well, whereas the walls are simply not there when the dxf file is viewed!

Jeffin90620: Fine, I did attach 2 files are you can see in my post above; but the images do not appear directly in the post, just the links. I shall attach again in this post and follow your directions to see what happens.

It is clear that for my current version of TurboCAD and usage of same, I must backup using dwg files. They work very well.

EDIT: aha! with the attachments, the png file shows directly in the post but not the pdf, which is what I attached previously.
