Layer names when exporting a DWG file

manu.seg — Wed, 20 Dec 2017 13:20:04 GMT

I all,

Your help would be greatly appreciated on an issue I have while exporting to DWG.

When I export from Revit all the layers names containing a period ( . ) in my DWG Export Setup is replaced by an underscore ( _ ) when the DWG is created.

See attached images. Is it possible to keep the period ( . ) in the name? I am supposed to respect a template that I have been given.

Hi @manu.seg

Please see mapping settings for a DWG or DXF export setup

Can you share a file with us to test and the steps you followed so that we can reproduce the issue and investigate further?

I can send you a private folder if you'd like.

Looking forward to your reply update.

Regards,

Thanks for your quick answer.

My model is 88 mb, so it might be better if you send me a shared folder
link.

Thanks

Hi @manu.seg

I shared an upload link with you.

Let me know if you have trouble accessing the folder.

I created a simplified model to illustrate what I'm talking about.

Here is the Revit and DWG file.

Note the layer name and modifier for WALLS in my DWG export setup and the
name actually exported to Autocad.

Thanks

@Viveka_CD, any update on the period exporting layers as an underscore conversion issue?

Hi @Anonymous

Sorry, this is taking so long!

I checked back again with the team working on your issue.

They were able to successfully export without any issues.

They have requested a screencast and the latest journal to investigate further.

Hi @manu.seg, @Anonymous

I'm checking again with AutoCAD specialists -

Some ACAD routines don't like specific punctuations (.) That's why they may be replaced.

Meanwhile here's a forum post that was shared (an article that suggests (.) periods are problematic)

I'll update when I hear more from the team.

(defun c:Rename_Layer ( / Lay_name)
(vl-load-com)
(vlax-for layer (vla-get-layers (vla-get-activedocument (vlax-get-acad-object))) 
   (setq Lay_name (vla-get-name layer))
   (setq Lay_name (vl-string-subst "." "_" Lay_name))
   (vla-put-name layer Lay_name)
)
)

is a LISP by @dbhunia that can be run in AutoCAD that changes all underscores in the layer manager to periods - not a solution, but a temporary workaround for the meanwhile.

Thanks @Viveka_CD - highly appreciated!
