# DWG

This will export an AutoCAD dwg.

## Inventor Drawing

**Conversion method**: [DataIO](<jobprocessor/code_reference/cmdlets/export-document:translatoraddin>)\
**Supported files**: *idw, dwg*

**Important**

```{note}
When exporting **multisheet IDW or DWG** files, Inventor creates foreach Sheet a own dwg file.\
By setting the flag *USE TRANSMITTAL* to Yes, a zip file with same name as the destination dwg file will be created instead.
```

## Inventor Sheet Metal

**Conversion method**: [DataIO](<jobprocessor/code_reference/cmdlets/export-document:dataio>)\
**Supported files**: *sheetmetal ipt*

**Important**

The **full list of arguments** for the DataIO addin can be found [here](https://help.autodesk.com/view/INVNTOR/2022/ENU/?guid=GUID-9F5075D3-00C5-47B3-8BF9-F97E8680B39E).

### How the Sheetmetal Settings relate to the Inventor User Interface

```{image} /jobprocessor/code_reference/cmdlets/export-document/img/pj_config_inv_dwg_sheetmetal.png
```

```{warning}
It is **NOT possible to use .ini-files created by Inventor** for this export!\
The sheetmetal export internally uses DataIO, which is not compatible to the configuration files created in the Inventor user interface (see the [Autodesk forum](http://forums.autodesk.com/t5/inventor-customization/dxf-flatpattern-export-with-ini-file/td-p/3796796) for more details).

### Spline

A [spline](https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2022/ENU/AutoCAD-Core/files/GUID-58316136-30EB-499C-ACAD-31D0C653B2B2-htm.html?us_oa=akn-us&us_si=8511eb6d-c164-45e0-940e-e0dbd9c8d28e&us_st=About%20Splines) is a curve that passes through a set of points which influence the shape of the curve.\
To disable the replacement of **splines with linear segments**, the flag `SimplifySplines` must be turned off.

This setting is activated by default and the corresponding **chord tolerance** can be ajusted with the option `SplineTolerance` (see *(A)* in the screenshot above).\
When this double value is set to 0, the spline passes directly through the fit points. With larger tolerance values, the spline passes near the fit points.
