Hello All,
Here I am again. Ok, here is the scoop. I have been trying to learn db's. So, I have done a few and I felt that this one would be a good one for me to really cut my teeth on. It is an "A325 & A490 High Strength Structural Bolt" with the values for the bolt coming from ANSI B18.2.1. I have most all of the lookup tables complete except for the arcs that make up the top of the head of the bolt. I used a hatch for the threads as it stretches and such accordingly when I adjust the values of the hatch boundary geometry. I figured I would use a hatch because I was being lazy and did not want to take the time to figure out the thread stuff.
Take a look at the block.
Kate helped me with the "r" arcs and I think dealing with the arcs in the bolt head top should be a similar function, but I can not figure it out. See the note I made in the drawing. Also, I am going to have to figure out the thread length thing as it does not display correctly when you have say... a 1 1/2" dia. bolt that is only 1 1/4" long...which I doubt exists because the thread length on a 1 1/2" dia. bolt is 2 1/4". I guess what I don't know is what the common... and uncommon bolt lengths are and their associated thread size. This makes sense if you dissect the dimensional data of these bolts...I think. hahahaha....
As always, I am NOT asking anyone to complete this db for me, but I am asking for guidance.
Once I have this part complete I can add a plan view from the top, washers and the nut. I figured I would do the plan view, washers and nuts via a vis state of those elements, but use a lookup table to define the geometry, which would also allow me to move the nut via a grip.
This may have already been done. However, I have done it, learned a lot so far and hope to learn more. Feed a man a fish, give a man a fish thing... and oh man you should see the fish I caught last weekend. hahahahahaha... Yeah baby.
I have separated all of the actions in a column format outside the actual block geometry as it helps me to organize and also makes it easier to click a param and see the action it's associated with.
So, here is a drawing with the db in it. As always, I appreciate the help and advice.
