Define bolt circle dia in hole wizard

Define bolt circle dia in hole wizard

Define bolt circle dia in hole wizard

(OP)
I do lots of circular bolt patterns but have been unable to figure out how to define a bolt circle dia when positioning the 1st hole in a circular pattern. I usually define it from the center of the BC as a radius. How can I create it 1st time around as a diameter. Thanks.

RE: Define bolt circle dia in hole wizard

Here's how I was able to do this:

Before going into the hole wizard, sketch a circle on the solid surface and check off the "For Construction" box.

Then go into the Hole Wizard and place the hole on the surfact. Put in a "coincident" constraint no the construction line and the hole center. If you want to put in an angular dimension from a plane, draw a centerline to the hole center then create the angular dimension.

That should do it.

RE: Define bolt circle dia in hole wizard

In my work, we also define hole patterns using a Bolt Circle or BC. To provide for this, we create & dimension the bolt circle, as a separate construction sketch, prior to inserting a hole-wizard feature. Then the 2d or 3d point for the hole(s) can be made coincident with the BC. If an angular orientation is required, then the separate BC sketch can include an additional construction line for the necessary angle.
This is a bit more work but in the end the hole feature(s) are defined as we require for manufacture.

Why not just sketch a circle in the position sketch created by the Holewizard, you can create all kinds of construction geometry in that sketch, you are not limited to just the points.  If your part is round then you could just put in the first hole then do a circular pattern using the axis of your part to generate the rest of the bolt circle.

I offered a solution based on the way I knew how to do it...Not necessarily the optimal way. Thanks for the input.

And when you detail it use the circular pattern Centermark option. It will make the B.C. in the drawing and put in radial center lines. Then you can dimension the B.C. with a driven dimension.

Design Library > Features > Inch > Hole Patterns > Circular Hole Pattern, or search for "circular hole pattern.sldlfp".  It is not a hole wizard hole, but if you study how a feature is made, you may be able to modify it to your needs.

  How about using the hole wizard and a polygon set to construction?

  That is how I generally do it.
