Hey I'm new to this site so hi!

Having some trouble with some geometry, I have modelled a turbine wheel using an imported blade (iges) and I now need to do some work on the shroud profile, I cant seam to get the sketch right, I was trying to use the 3d sketch from the original iges but I cant use this sketch to create a revolved piece,

Any ideas?

Thanks

Not exactly positive of your case but in the past I have typically drawn shrouds with a spline in a 2d sketch and then revolve around a centerline.

That’s my intension, but I'm unsure how to get to a 2d plain sketch using the 3d one, the shroud line from the 3d sketch is only 2d, I can't seam to cut and paste?

Cheers

I don't think you can revolve a 3D sketch; it has to be a 2D sketch.

Are you trying to revolve an imported 3D curve (that is only 2D, but imported into SWX as a 3d curve)? If so, you could create a new sketch (2d) on a plane that lies on the curve profile. Then use convert entities to copy the curve to the sketch. Then you can revolve the sketch.

Arlin, I'm trying to do that but I can’t manage it. I can’t get the 2d part from the 3d sketch into a 2d sketch. (if that makes sense)

Convert entities, not come across this and it doesn't seam to change from a 3d to a 2d.

A 3D sketch is in 3D space. You can't copy a 3D sketch into a 2D sketch. You are going to have to offset a plane and re-create your sketch there.

Step by step....

1.) Determine your axis of revolution. Create an axis or 3D sketch line to demarcate the axis.

2.) create a datum plane through the axis at an orientation that best defines your section.

3.) Start a 2D sketch on that plane. Use "Convert entities" to copy the desired edge into the sketch. Make sure the sketch has a centerline collinear with the axis of revolution.

4.) Create a revolve from the sketch.

Many thanks, it worked!
