Modify layers before exporting DXF file using iLogic rule

fsdolphin — Wed, 26 Jul 2017 13:00:04 GMT

Hi,

I'm currently trying to automate the process of exporting a DXF in Inventor using iLogic. Luckily I was able to find this article which contains the code for the exporting process, this code does almost what I was looking for except that I would like to modify some layers before doing the export.

How can I modify the following code to be able to modify layers before exporting the DXF?

FYI- I looked at the APIs for the but I'm not sure how what I need.

    If ThisApplication.ActiveDocument.DocumentType <> kPartDocumentObject Then
        MessageBox.Show ("Please open a part document", "iLogic")

    FilePATH = InputBox("Enter a FilePATH for part file", "iLogic", iProperties.Value("Custom", "FilePATH"))

    iProperties.Value("Custom", "FilePATH") = FilePATH

This is how the layers should be modified to...

Hi fsdolphin

That code was from my blog on Cadline Community 🙂

The settings for the layers are saved in a .ini file that Inventor references for the export. These files are stored in your design data folder, which by default should look something like this: C:\Users\Public\Documents\Autodesk\Inventor 2018\Design Data\DWG-DXF.

To create a new .ini file, set up your layers are required, and then choose "Save Configuration". Best practice would be save this .ini file to the design data location.

Manually publish a DXF, and Inventor should now remember the last .ini file you used, so the iLogic code should now export out the DXF's with the layers you set up.

I hope this makes sense

Another option is to explicitly add the .ini file and location to the code, as shown below:

Dim strIniFile As String
        strIniFile = "C:\Users\Public\Documents\Autodesk\Inventor 2018\Design Data\DWG-DXF\YOURiniNAME.ini"

        ' Create the name-value that specifies the ini file to use.
        oOptions.Value("Export_Acad_IniFile") = strIniFile

fsdolphin — Thu, 27 Jul 2017 11:28:23 GMT

@Anonymous First of all thanks a lot for the code, very useful.

I already have a .ini file but saving manually and then trying the iLogic rule as you suggested it doesn't work, it doesn't remember the settings.

FYI - The .ini file is saved/located in a local network not in the Design Data folder, I'm not sure if it make a difference.

Anyways, I would rather have a reference to the file in my code.

How can I reference the .ini file in code?

Thanks a lot.

@Anonymous I really like your method but I can not make it work.

Where exactly should I be adding your code?

Where do I add this line of code

oOptions.Value("Export_Acad_IniFile") = strIniFile

I got error: `oOptions` is not declared. It may be inaccessible due to its protection level.

Thanks a lot!

try adding this before oOptions.value:

Dim oOptions As NameValueMap
oOptions = ThisApplication.TransientObjects.CreateNameValueMap

fsdolphin — Fri, 28 Jul 2017 11:53:11 GMT

@SašoPrijatelj Thanks a lot for your comments. By adding the code you suggested did silence the error, but it didn't apply the settings from my .ini file. The main issue is that I'm not sure where exactly does the following block of code needs to go...

SyntaxEditor Code Snippet

    Dim oOptions As NameValueMap
    oOptions = ThisApplication.TransientObjects.CreateNameValueMap
    
    Dim strIniFile As String
    strIniFile = "C:\Inventor Working\Libraries\configurations\Kenall DXF Configuration.ini"
    ' Create the name-value that specifies the ini file to use.
    oOptions.Value("Export_Acad_IniFile") = strIniFile

I added it at the beginning of the Cadline subroutine, but the settings in my .ini file do not get applied. I don't get any errors it just doesn't see the .ini file.

I this where the link to the .ini file should be?

Hi fsdolphin

I'm exactly at the same spot as You, but i might have found something that will help the both of us to some degree.

The link below I've found talk about generating DXF's for sheet metal parts from an Assembly level, but as for me is not fully functional, because it only supports one assembly level of complexity, it doesn't work on multi assembly multisheetmetal part construction without further rewriting.

Drive Rule in Sub Sheet Metal part to Export DWG/DXF by DataIO

Anyway, for the sake of your post, there is an interesting line of code You can Use, under Sheet metal part rule which might help You to modify some options for the particular layers You are interested in. Anyway for now I have nothing more, and at the moment Im trying to apply that coding into my rule and to expand it, if I have something working I'll post it up.

PS.

The code saso & appsUP8FN wrote I personally found only in a rule for exporting DWG/DXF's from a drawing level, not from parts sheet metal one.

@M Thanks a lot for your reply, it helped me a lot. I now have it almost where I need it except one thing, I need IV_BEND and IV_BEND_DOWN as dashed lines.

sOut = "FLAT PATTERN DXF?AcadVersion=2004&RebaseGeometry=True&OuterProfileLayer=0&OuterProfileLayerColor=0;0;0&InteriorProfilesLayer=0&InteriorProfilesLayerColor=0;0;0IV_BEND;IV_BEND_DOWN;IV_OUTER_PROFILE;IV_INTERIOR_PROFILES;IV_FEATURE_PROFILES;IV_FEATURE_PROFILES_DOWN;IV_ALTREP_FRONT;IV_ALTREP_BACK;IV_ROLL_TANGENT;IV_ROLL&InvisibleLayers=IV_TANGENT;IV_TOOL_CENTER;IV_TOOL_CENTER_DOWN;IV_ARC_CENTERS;IV_UNCONSUMED_SKETCHES"

Any idea how can I make IV_BEND and IV_BEND_DOWN dashed?

This is how they should look:

IV_TANGENT; 'Off

IV_TOOL_CENTER; 'Off

IV_TOOL_CENTER_DOWN; 'Off

IV_ARC_CENTERS; 'Off

IV_UNCONSUMED_SKETCHES; 'Off

IV_BEND; 'On Dashed

IV_BEND_DOWN; 'On Dashed

IV_OUTER_PROFILE; 'On Solid

IV_INTERIOR_PROFILES; 'On Solid

IV_FEATURE_PROFILES; 'On Solid

IV_FEATURE_PROFILES_DOWN; 'On Solid

IV_ALTREP_FRONT; 'On Solid

IV_ALTREP_BACK; 'On Solid

IV_ROLL_TANGENT; 'On Solid

IV_ROLL; 'On Solid

To make IV_BEND and IV_BEND_DOWN dash lines you need to add the following to your sOut string.

&BendDownLayerLineType=37639&BendUpLayerLineType=37639

Kudos!

I was looking a line of code that would omit all bend lines for sheet metal parts when creating DXFs & found this line of your code:

sOut = "FLAT PATTERN DXF?AcadVersion=2004&RebaseGeometry=True&OuterProfileLayer=0&OuterProfileLayerColor=0;0;0&InteriorProfilesLayer=0&InteriorProfilesLayerColor=0;0;0&InvisibleLayers=IV_ARC_CENTERS;IV_TANGENT;IV_ROLL;IV_ROLL_TANGENT;IV_ALTREP_BACK;IV_ALTREP_FRONT;IV_FEATURE_PROFILES_DOWN;IV_FEATURE_PROFILES;IV_TOOL_CENTER_DOWN;DIGI_MARKER_TOOL_1;DIGI_MARKER_TOOL_2"

I added the IV_BEND & IV_BEND_DOWN to the list of Invisible Layers. Here was my final version of that same line of code:

sOut = "FLAT PATTERN DXF?AcadVersion=2004&RebaseGeometry=True&OuterProfileLayer=0&OuterProfileLayerColor=0;0;0&InteriorProfilesLayer=0&InteriorProfilesLayerColor=0;0;0&InvisibleLayers=IV_ARC_CENTERS;IV_TANGENT;IV_ROLL;IV_ROLL_TANGENT;IV_ALTREP_BACK;IV_ALTREP_FRONT;IV_FEATURE_PROFILES_DOWN;IV_FEATURE_PROFILES;IV_TOOL_CENTER_DOWN;DIGI_MARKER_TOOL_1;DIGI_MARKER_TOOL_2;IV_BEND;IV_BEND_DOWN"

Works like a charm! Thanks!

Muito obrigado, resolveu meu problema.

Uma outra dúvida se souber, quando eu exporto em DWG ou DXF ele não aparece a imagem em miniatura dentro da pasta, é necessário abrir o arquivo DWG ou DXF e salvar para aparecer.

Existe uma forma para aparecer a miniatura do arquivo nas pastas após exportação?

Obrigado.

How do i apply a custom linetype named LaserCut to the outer line of my flatpattern? for dxf export
Ive defined it in the standard .lin file and im able to use it in sketches when i change the properties of lines.
My goal, is to define the path for the laser, so it leaves 1mm gaps when it cuts the plates outer brim
