2d vs 3d sketches and hole wizard

2d vs 3d sketches and hole wizard

2d vs 3d sketches and hole wizard

(OP)
When creating holes using hole wizard...  

1.  If the points are predefined in a sketch it will create a 3d sketch as part of the feature and leave the original sketch that it is referencing.  
2.  If you instead choose to create the points that will define the hole placement "inside" hole wizard it will create a 2d sketch inside of the feature.  

Can someone explain the differences this will make, any downside to the either option.

RE: 2d vs 3d sketches and hole wizard

DrGonzo,

I prefer to predefine my sketch points with a 2D sketch since I often move holes around after creating them.  This way, I can easily edit my hole positions in my 2D sketch by changing dimensions in the defining sketch.

You may be able to do this using the second option you discussed--I'm not sure.

RE: 2d vs 3d sketches and hole wizard

I find it very easy to just start the Hole Wizard, and start plonking down sketch points where ever I need them.  Once I exit, it's a simple matter to locate the points with dims.

Thanks for the responses so far, it is interesting that one for each method came in.  One of my co-workers and I are having a debate about the validity of either method.  I am with the first, he the second.  

I can see the benefit of doing the sketch in hole wizard, but can't really see the downside of the first method.  I generally feel if the model has good integrity and adheres to design criteria then the method that works best for you is.  

Any other opinions, educated or otherwise.

Thanks,

RE: 2d vs 3d sketches and hole wizard

I can see some possible pros and cons to both, but they are really nitpicky stuff. Just on the basis of not loading up models with unecessary features, I would tend to go with doing it inside the wizard. Before 3D sketches, that's what you always did.  Remember that the more features and relationships in a model the slower it is.  Not a big deal until you get to larger assemblies.  Also having a good grasp of basic geometry helps in minimizing the unecessary data in sketches.

I would imagine they added the 3D sketch idea so you could use points that already existed in sketches built for other purposes.
