Importing DWG or DXF into inventor to make a sketch

How do I import a DXF or DWG 2D profile. I am trying to take a simple 2D dxf and import it into something I can make an extrusion for in Inventor. When I import it and open a sketch there is a blank page. I can see it when I open it in Inventor but I can't do anything with it other than look at it. So I am guessing that it would need to import into an ipt file so I can extrude it as a sketch. AutoCAD has changed so much I can't even make a 2D sketch there anymore. It has changed in the last 20 yrs to where I don't know how it works. I have gotten spoiled by Inventor and have lost touch with AutoCAD. It should be simpler than it is since DXF is an AutoCAD format.

Hi Perry,

 

Did you try DWG Underlay workflow? In the part you want to overlay the dwg file, Import -> pick the dwg file -> pick an origin plane -> pick the origin point to place the dwg geometry. After that, create a sketch on a parallel plane -> Project DWG Geometry -> select the dwg geometry.

Many thanks!

You can check out both the Underlay workflow and the Import workflow with the 2 guided tutorials.

Not seeing much about underlay workflow in Inventor 2019. I don't see options for that in import settings.

An import workflow converts ACAD geometry to Inventor geometry and there is no link to the source ACAD file.
There is no specific "underlay" command or option. Underlay describes the workflow.
Start an Inventor part file and use the Import function in the 3D model tab. This brings in the ACAD geometry as an xref. This workflow creates an associative link that allow changes to the ACAD source file to drive the geometry in Inventor. It also allows you the ability to project only the geometry you need from the ACAD file.

If you want to see both workflows in action, open the two tutorials and watch the videos.

Hi Perry, you mention AutoCAD. If all you want to do is just get a shape from DXF to Inventor, this is the way I always did it.

 

Open in AutoCAD

Window select

ctrl+c

 

Switch to Inventor

Start your sketch

ctrl+v

Fully Constrain everything

 

If your DXF data is good you'll be able to extrude straight away.

The above workflows are better if your DXF is likely to change at any point as it'll be associative and update in Inventor.

Thanks that works. Cut and paste into the ipt sketch panel. I am sure there are other ways to do it but that is fast and easy. Open in AutoCAD then select, Cntr C, then open a sketch and paste.
