Hole Wizard - Pre-Selection vs. Post-Selection
Hole Wizard - Pre-Selection vs. Post-Selection
(OP)
I've got a co-worker that is new to SolidWorks and he constantly uses the post-selection method of inserting hole wizard holes and for some reason they bother me. Usually for me that means there is something wrong/dangerous about the technique, but I can't put my finger on it.

I pre-select a surface to compel 2D-sketch when adding holes to a planar surface. Even then, I usually just dump one hole onto the surface and finish up with the hole-wizardry. I like to add/constrain holes after the hole wizard feature is created because then I can add any necessary construction geometry and constraints that I can't add while in the initial hole wizard dialog.
RE: Hole Wizard - Pre-Selection vs. Post-Selection
Yes, different is good and bad at the same time. I'm just trying to be open-minded about it as I've been told too many times untruths that I would've benefitted from using, and I'd rather educate.
I think I'll convey the idea of issues regarding the dimensioning problems and see what happens. I'll try to get used to it in the meantime, and see which of the theories come out ahead.

RE: Hole Wizard - Pre-Selection vs. Post-Selection
The overwhelming majority of holes that I model with hole wizard are intended to be perpendicular/normal to the face on which they are created, thus I pre-select.
Very rarely do I need to model a hole on a compound angle, but that is the case in which I use the post-selection method.
As stated by others above, that is the method which I've learned through trial and error will cause me the least amount of grief/errors when editing.
I'd recommend suggesting that your coworker consider the possibility of future edits benefiting from the 3D sketch and again, avoiding their use when possible.

Are you guys telling me that I can click on the face BEFORE clicking on the Wizard thingy? Oh, that's new! I'll try it.
Thanks,

No, that's not new. It's always (at least since SW2000) been that way.

On plan view all the dimensions will look fine but the attached picture shows how the 3DSketch can go wrong. The holes were misaligned by 1mm along the 100mm dimension and 2.5mm along the 200mm dimension.
My advise is, always pre-select where possible

I have attached a pic that shows what I mean. The model on the left was done with post-pick and the one on the right was done with pre-pick.
