How can I create a disc with a random amount of holes on a bolt circle diameter?

Nov 23, 2007 13 Replies

I need a way to create a disc that has a random amount of holes on a BCD. I can control the disc diameter, disc thickness, hole diameter, and bolt circle diameter using equations and design tables. I cannot find a way to use a design table to control the amount of holes on the bolt circle. Can this be done or am I stuck in an AutoCad way of thinking?



Thanks in advance


By "random amount of...", do you mean "arbitrary number of..."?

Jeff, I tried to respond last night but it seems not to have posted. The information you're missing is a way to reference the value for the number of holes in a design table or equation. If you created a hole with a cut-extrude, cut-revolve, or hole wizard feature first, then used a circular feature pattern, this is easy. Double click on the circular pattern in the tree, so that the dimensions appear in the main window. Near the axis you used to create the pattern should be a dimension showing the number of instances, with no leader or dim lines. Right click on it and the name of the dimension will show at the top of the context menu; you can also click on properties to see the name if it's too long to fit. In my test, that dimension was D1@(circularpattern). If the pattern is in the sketch rather than the feature, I'm not sure what to tell you. There doesn't seem to be an obvious way to obtain that number. Then again, if you're using sketch patterns, you may want to consider feature patterns instead as there are also other advantages:

Seeing as there is little or no help here I posted your question at my forum.

I am pretty sure you will get a answer and not some useless gibberish

Ben,

In your opinion Mark Treadwell's response is little or no help?

Happens, no worries. I just wasn't sure if you were discounting Mark's input.

Following Mark's directions the full dimension name will look like this D1@CirPattern1.

None taken - happens all the time when it takes any time to compose a response. I just hope Jeff didn't give up too soon on finding an answer here.

I hope he reports back and lets us know his progress.

This is what came to mind when I first read his post:

Driven from a table, where the # of holes, hole diameter & BHC are variables.

It has been brought to my attention that I may have come off as pompous and arrogant saying that 'real' answers can be found at SolidMentor and insinuating that here you cannot find answers. I did not mean that at all and apologize to those that took offense.

I was just tired of seeing someone get a ton of answers not related to his problem and offered another possible place to post his question. I still see value here at CCSW and come here to view and very occasionally try and help out. I believe the more resources you exploit the better your answer to a problem can be and using CCSW is encouraged by me and the quality of answers is just as good here. Just you have to wade through a bunch of..... well I am sure you know what

Yep.

You come off as a spammer.

Good to know and thank you for the heads up. No more spam from me. Sorry to have contributed to the problem. I was only trying to help find solutions.

Later....
