Importing DWG into Sketches

i am trying to import a DWG of a floor plant in to inventor, so i can extrude it and make a 3d model of it, but when ever i try to import it, it takes a lot of time, even if isn't complicated and it's practically unusable. is there any settings that i can use to improve this?

In autocad, try purging the drawing first. 

Also use overkill command to get rid of extra lines you don't need. 

Does that help?

Can you Attach the *.dwg file here for diagnosis?

Get rid of text, dimensions and hatch patterns.

I would probably break this up into several drawings.

I would be concerned about -dwgunits

Typically, the sketch function "Insert ACAD file" is slower than copying from ACAD (Clipboard > copy with base point) and right-click pasting it into the Inventor Sketch.

 

After cleaning up a bit of the first floor layout (removing as many hatches and text as possible) we get a good fast result (less than 5 secs to paste), and other layers even came separate, which is a bonus:

Hi Folks,

 

Another workflow to consider is DWG Underlay (Part -> Import -> AutoCAD dwg). This will import the DWG geometry as a transparency on a selected workplane or planar face. Then you can create a sketch on the plane and use Project DWG Geometry to include the needed DWG geometry in the sketch. It should be faster than the traditional import to sketch workflow.

Many thanks!

@JonnyPot 

Thanks for posting this question. I was having very same issues. My dwg imports were horrible to work with. Very slow and would at times lock up inventor. This post has helped me create a workflow for better dwg imports. Way faster and easier to work with now.

 

My work flow is this now:

1. In ACAD I will wblock a section of a sketch and save it as a dxf or dwg.

2. In ACAD open the newly created file and

  • select all and move all to layer 0
  • use the purge command to remove all unused layers, block...... stuff
  • use the overkill command to remove all duplicate lines
  • use the dwgunits to ensure correct drawing units

3. File is ready to import into a sketch, block, or underlay

 

Thanks again!

John
