Block of a bolt, array problem
« on: February 23, 2013, 08:43:48 PM »
I've been getting acquainted with dynamic blocks, (yes about time)
The attached block "Bolt No Nut" is one that I am having a problem with (ACAD2006)
The way it is designed works OK. That is when you stretch it the threads array & display properly.
The issue is that the dimension needs to be the bolt length like this picture, but the way I have designed
it the length is from the thread that is arrayed. I'm sure I'm just missing the correct procedure.
Also attached is an example of a metric screw which represents what I am ultimately trying to achieve.

Note that using it a drawing I scale the block to the correct size (close enough to actual size), then stretch to length desired.

Hey CAB,

I believe what you want is to add a "lookup" action to the length of the block.  Unfortunately I've never had to do it myself so am unable to help ya :/ sorry

Yes, the lookup will come once I solve the current problem.
Looking at the screw block you see that the length linear parameter encompass the entire screw.
My bolt needs to encompass the entire shaft length.

Is a pain I see... the length is no problem, but getting the array right is a pain. I'm stuck where you are lol. Hopefully someone will jump in and save the day.

Thanks for trying.
The Swamp is slow on weekends and I'm in no hurry.

I did find some more video tutorials I'm viewing now.

OK, figured out how it works.
I was able to have two separate linear parameters & stretch & array actions.
The key is to select a stretch area that includes one part of the array - linear parameter.

Improved block.   8-)
Threads re-sized to allow bolt length to stretch in increments of 1/4"
Min length is 1".

Okay, so what's the difference between yours and the one I tried that's making the one I tried not work lol. This is driving me nuts!   :lol:

Look at the picture I posted. The dotted rectangle is the "stretch frame" for the stretch action.
Notice that it grabs one leg of the array "linear property".
I believe that that is the key to making the array action happen when you stretch the bolt.

FYI, I am working on an anchor bolt and some others.
See attached.

OK, I just tried your block, I had to re-apply the stretch action.
It is critical that you select the linear property of the array and I think the grip too when asked to select objects.
You had the stretch frame correct.

Procedures are quite tricky in the dynamic blocks as I have discovered.
I'm not sure of all the correct procedures yet.  :?

Think my stuff is bugged... gonna try this again at work. I also reapplied the stretch, selected the linear parameter, and the array grip. I left the grip on.  The stretch moves the array grip, but the threads don't update until I actually select the grip for the array. So lame

Very cool blocks btw! If I was a nuts and bolts guy I'd definitely "borrow".  Unfortunately I just play with dirt lol (I work in the land development world).

I touch the edges of land dev.  :-)
When I do crude site plan for the houses I design.
I also do some drawing for an engineer that includes some very limited site work. It's fun exploring outside your own box.  8-)
The bolts are for drawings I am doing for the engineer, very small bridges, metal parts for water treatment plant, etc.
The dynamic blocks will save me some time. I plan on doing a profile view of angle iron with a wipeout next.
The angle Iron block will help a lot, see below. Being able to stretch from both ends.

This is a perfect example of where one could benefit from using ASD.

I don't work in this area regularly so I can't justify the cost of more software.  :-)
Plus I like to explore but the Angle Iron Block has got me stumped at the moment.
