AutoCad 2d to Creo 3D

I have an AutoCad drawing and I would like to create 3d part in Creo. What is the best way to preform this operation.

Thanks

There is the option to use AutobuildZ to semi automate this process. I have never used this, I just build the models from scratch.

I would typically import some drawing views using trace sketch functionality and rebuild the part using the views as a visual guide.

Info on how to import the drawing views into Creo.

Thank you for the information, Unfortunately, I do not have the dimensions to create a model. 

Do you have any type of scale reference for the 2D data that you have? Share an image of the drawing to get more specific suggestions.

I usually just import the cad in to the model. I orient the import based on a coordinate system. If it's anything complicated, I will import autocad in 3 or more views (all based on coord systems to get the orientation I need and use those views to project sketches and create the geometry.

The only Dimension that I have is an Outside diameter. My model in Autocad is 1:1. I have created a .dxf file but I can not extrude once i bring the file into the Creo sketch. I have verified all polylines in my Autocad drawing are closed but I can not get the part to extrude. I am just looking for the simplest way to create a model from the 2D Autocad model. Any specific steps to try without download any 3rd part software?

A sketch is just a sketch.

Bring the import in to a part file and you can make sketches needed from there.

You have a scale reference if you can access an Autocad model that is 1:1 . This suggests that you can import one or more views into the part model using the trace sketch functionality and scale them accurately. Do not use an imported DXF as your sketch, that is not a best practice in this context.

 

This is an example of using a 2D drawing view to create 3D geometry using trace sketch functionality. Note that the drawing view is a digital analogue to tracing paper and is not a parent to any of the features or geometry in the part model. The drawing views are placed on a plane and scaled to serve as a guide to build Creo geometry.

I don't disagree with anything mentioned by tbraxton. It's all about the end use of the model you are creating.

I do use imported DXFs to create my models. If it's to create a new part, fully dimensioned for manfacturing, I will use the DXF to get the sketches but then go back and break all the references to the DXF and then apply the appropriated dimensions.

If I am making a model to just have a model for use an assembly, I use the DXF to create the sketches but I typically don't break the references. I turn off the import using layers.

You will need to decide your path based on what you need and what your requirements are and your end uses of the model. No one but you (and your company/customer) can really be able to give you an exact course of action.

Forgive me as I am new to Creo, I really appreciate the help. I went to file open in Creo and I opened my .DWG file.  I did not import anything. What is my next step or did I miss something up to this point?

Create a new, empty part. Then go to Get Data - Import.

If the ACAD is too new, it likely isn't supported. Depends on your version on creo and the version of ACAD.
