Bolt object adjustment

Anonymous — Thu, 26 Jun 2008 17:27:24 GMT

Hey,

Who can tweak the code on a 2D bolt that I have so that the nut and washer doesn't' shrink and stretch when I adjust the length?

I'd appreciate some help on that. I see that it works on a great bolt that you can make into a carriage bolt and such, I want it to work that way on this lag bolt that I have. I'm a little tired of having to choose Lag 4, Lag 6....depending on the bolt length I want.

I imagine if you know what you are doing it would only take a little time.

Thanks.

Not sure what lag you are talking about. Could you elaborate?

I have a 2D library part of a lag bolt with a washer and the hex end as well as a 2D library part of all thread rod with a washer and hex on each end. I want to be able to have one library part that I can lengthen the lag's shaft and not have the washer and hex distort as the shaft lengthens and shortens. There is a free download bolt part that does this but I am incompetent (and choose to remain) in GDL. I want to have the washer and hex remain at the fixed size and then stretch the bolt to 12", 14", 6" etc.

Thanks for any help. I'll pay for a bolt that works, I know it will take someone some time. Let me know if you have the abilities to do this.

If you could send me the library part I'd like to look at it. No gaurantees as I am not an expert in GDL but I'd like to give it a try.

There is a bolt on the site opengdl
http://www.opengdl.org/gdl-de/obj00010.htm
But it is for the metric system.
You want something like that?

-Valery, yes, like that. We have that bolt and use it in some applications. The "lag" isn't ideal and we also want the threads to show the full length when we use it in an "all thread" application. But as to the nut end not shrinking, that would be just right with an added washer.
-4thorns where can I send the part outside of architalk?

Derek,

You can send it to my email address, 4thorns@roadrunner.com. After I read and replied to your post I decided to mess around and see if I could script a lag myself. I searched online for lag specs and found something that I should have thought of to begin with. Different size lags have different size heads. When you say the heads are stretching could it just be that they are adjusting to the lag size?

No, the bolt is not correctly adjusting to the lag size, it stretches in proportion to the length of the bolt you make. We want the washer and hex head to be consistent no matter the length of the shaft.

We want the 2D lag to work like one side of the shareware bolt (with the consistent hex and washer) but have the other side look like our 2D lag with the shaft and threads at the end and then be able to define the length by stretching the part and or by picking a length from a pull down (like you can do with the 2x4 part, you choose “custom” and make it what you want, or you define by choosing 2x4, 2x6…)

Thanks for your PM

Derek,

Just wanted to let you know I haven’t forgotten about the lag object. Most of it is scripted but it’s been a little hectic around here so it’s not done yet. It’s based on lag manufacturers’ specs that I found online so it creates an object that should be fairly accurate. It has the ability to be “All thread” as you asked or partially threaded. It’s set up now with a pull down menu for the diameter of the lag(1/4"-1"@1/8" increments). The length is determined by the user. I can add script to put in a menu for the length if you would like. I would just need to know all the lengths that you need. One thing I did notice is that your lag was created by saving 2d lines as an object. Anytime something is saved this way (3D Objects as well) and you stretch it, Everything will stretch. In order to get it to act the way we want it to, changes would have to be made to the script or it would have to be made from scratch.

Hi,

go the following site: http://www.archicadselect.com

You will have to register.

Then go to "Archicad Objects"

Download the "Archicadselect Library Archive". It is the eleventh items about 9 MB and its free.

There is a 3D "Bolt Object".

Hi Derek,

First of all I want to give a big thanks to power users of the forum. Without them, those of us without a ton of time to study all the documentation would have a hard time learning the finer points of GDL. A special thanks to Tom Waltz for taking the time to look over my script and giving it a good review!! (Not sure what I’d have written if it had been bad) I hope that all new members appreciate that these people are taking time out of there own lives to help us out.

Well, it’s done. I set it up to have a minimum length of 2”. There is no maximum. You may also notice that anything less than 5” will be “All Thread”. This is because anything I found Online was manufactured in this way. If you choose to not have “All Thread” on, then the threads will be half the length of the bolt(measured from the underside of the head, to the point), plus ½”, again this seems to be the norm. I picked the hotspots based on how I would normally place it (plus a couple of extras) but if you would like to add more or remove existing ones I can do that for you. I see in your signature that you are using AC10. I use versions 9 & 11 so I’m sending it to you saved in version 9. Check it out and see if it works for you. If you have any questions or would like to see something changed let me know and I’ll see what I can do.

Doug
