View 9 RepliesWe're new to using bolted connection in our piping systems. They work great within a pipeline, connecting flanged fittings, etc. Where we have an issue is across two pipelines. Each pipeline is a sub-assembly, so in the bolted connection wizard it is impossible to select the mating flange on the other sub-assembly as the termination plane for the bolted connection. I want the bolted connection to show up in the BOM for one or the other sub-assembly, not at the top level.
Right now what I am doing is manually inserting what would be the mating washer and nut, from the CC and using an offset Insert constraint to make it appear to sit on the face of the mating flange, then pattern that... and THEN run the bolted connection for the bolt and another washer on the other side. This works, but is very time consuming. How this could be done across sub-assemblies, with all of the parts in one sub-assembly's BOM?
We'd like our bolted connections to show up as assemblies in our parts list rather than individual parts.
We've modified our CABoltCon.Imperial.xml template to make the assemblies B.O.M. structure 'Normal' rather than the default 'Phantom'.
Now we'd like to drive the assemblies description based on the bolt size used. For example, the description in the parts list would read "5/8" HEX BOLT C/W NUT AND WASHER".
I am working in an Inventor Assembly .iam, I have about 250 fasteners (screws) that are constrained to a flat washer and lock washer. I would like to put them in as a single unit (sub assembly if you will) and then promote or explode them in the top level so that my bom has 250 screws, 250 washers, and 250 lock washers all at the same level, not associated to one another except thru the constraints that were entered in the original assembly. I have tried Promote but that doesn't work because it removes the washers from the original file and I end up with only 1 instance of the assembly. Am I approaching this incorrectly? Is there a better way? I run across this scenario with different components quite often.

The issue arising is the individual components need to be called out on the upper level, but in the drawing are all showing up as the same balloon.
i have a valve vault assembly that i am creating that has two headers running through a large cylinder vault. how i get a total BOM if i were to create the header assembly file separate from the the total vault assembly file. is there a way to explode the header assembly bom when i do the drawing.

If not can I run the FEA on the structure as a welded frame & get loadings at the connection points to manually calculate bolted connections?
I've copied Standard CC libraries to read/write libraries and modified the tables. Mostly fasteners. I've prefixed the family name and family description with our company name. When I "place from content center", it's easy to see our content because the families are prefixed with our company name. However, when I use bolted connection, some of the families do not show our family name as a prefix like "place from content center" does. People constantly pick the wrong fasteners. They select fasteners without our Item number, etc. Then, they need to delete the fastener and try again. I can't seem to get bolted connection to show some fasteners with the company name prefix like Place from CC does. However, some families do show it.

Is it possible to break my bolted connection, so that i can change the information given by inventor in the BOM? Its always grayed out and i can`t seems to find a way to make it "ungrayed".
I could change it directly on the .idw but me and my project leader would like to not go on that road. Our teams are seperated in to two. Ones in charge of modeling & the other is in charge of the presentation. We would like to give, as much as possible, not to much leeway on those in charge of the presentation.
I have a simple bolted connection (bolt, nut and washer) and have tried to pattern this to make a toal of 4 bolted connections in a linear pattern. The preview looks fine however when I hit apply the patterned components disappear. I'm not sure why this is, I am using Inventor 2013 64-Bit SP 1.1

I installed a bolted connection into my assembly and realized I chose the wrong length. I simply want to delete the connection and start over but there is no option to delete.Ctrl-Z will not let me back out of the connection either.
View 2 Replies View RelatedI've got two pieces with 11/16" diameter holes for 5/8" bolts.
When I use Bolted Connection to place nut/bolt in the hole, it detects the 11/16" hole and sizes the bolt to look for 11/16" bolts. There aren't any 11/16" bolts so the window shows no bolts. I have to manually choose 5/8" for the bolt size in order to get a list of bolts to choose from. In my reading, i was thinking this was supposed to have been fixed by 2010, is that not correct?
Also, in testing another theory, after placing the bolted connection andt then editing the bolt size to 7/16" or 1 13/16" in diameter. The bolt doesn't update it's size to reflect the change in the hole. Is there really no correlation here? Is a manual change to existing bolts, nuts, washers, etc going to be necessary if the hole size changes? If i change the thickness of the plate(s) the bolt is going through, using autosolve updates the bolt length, but nothing seems to be checking the diameter of the hole.
If true, kinda harst to be able to make a completely parametric assembly of everything but the fastners.I'm using the Hole method on the bolt connection dialog with pre-existing holes that do not have threads on them.
When i try to make a bolted connection my "click to add fastener > standard/category" box is empty. my hole, which used hole command, is 11/16" and the bolt only needs to be roughly 2" long so im not demanding odd fasteners.

I am trying to assembly some party, when after i do the bolted connection and select the fastener, after i choose him i cant select the length, he do this automatically. and because of that my fastener come out of my part.
Where can i change the length of the bolt? i use inventor 2012.
So I've got this part, and it's got bolted connections. There's two of them, and each one is a pattern of multiple #10 machine screws.
No matter what I do, one of them will always have a lighting bolt next to it, as shown in this picture:
Rebuild All doesn't fix it. Manually editing the bolted connection will fix the lightning bolt ... but it will invariably switch to the other bolted connection instead.
Also, another fun little thing I've found: if you grab one of the screws with the mouse and drag on it, only the first bolt in the pattern seems to be actually constrained to the hole. The others appear to have pretty much just distance constraints, maybe plane-axis constraints. You can rotate the whole pattern around the hole that the first bolt was set in. This doesn't seem like a good behavior to allow ...
Anyway, the data set for the above image is attached. The screws themselves aren't, but they're just content center parts and should get automatically generated if you open the assembly.

Bolted connections between two angled surfaces?!?
Is this possible ?!! Ive been working in various CAD packages and have found this to be an issue every time. Say for instance you want to bolt through a wall onto a tapered flange, how can you select a non parallel face as the start or finish surface?
All of the sudden I cant get to my bolted connection dialog box.
1. The command runs and the prompts at the lower part of the screen show.
2. Have loaded and unloaded / restarted via add ins.
3. Have looked behind all windows ect on both of my 2 screens
I`m joining pipes together using the nut/bolt/washer method using constraints in assembly then using pattern feature.I`ve not used the bolted connection generator before so i am looking for some feedback on whether this is a better method to use.Is there any advantage to using the bolted connection generator over the placement of nuts/bolts/washer with constraints and then using pattern feature?

I other words, special nuts / bolts that do not appear in the Inventor standard libraries, that are essentially user created, defined and published.

I've lost my Bolted Connection Templates... you know, the pre-defined bolt-washer-nut selections available for re-use at the bottom of the Bolted Connection dialoge box.
Did I lose or over-write a file? What file do my Bolted Connection Templates live in?
When a bolted connection is used, the bolt changes in length as the stackup of hardware increases and decreases. I have noticed that if I do not grab the red arrow to adjust the length, the amount the bolt extends past the nut
seems to be only about 2 threads. What is the formula Inventor uses to determine this extended length?
Having trouble bolting through a beam onto a tappered face of a channel. In RL a tapered washer would be used, though they exist in Content Centre it doesnt work with the application.
View 1 Replies View RelatedI have a problem with the Bolted Connection tool in inventor. When I use it to place fasteners in my assembly everything works fine, i can select the material I want, etc... The problem is whenever I need to change something in it, the fasteners changes to the first one in the list that appears when you click the ... button, which means that I always get the wrong fasteners. The workaround we found was to click the ... button again for all the fasterners, and this has to be done in the right order (start to end) otherwise I will get again the wrong fasteners and to select the fasteners again.
One more thing, I'd like to know if it is possible to have a more user-friendly way to change the bolts in bolted connection. I would like it to be like when you import a component from the content center, with that dialog box. As for now, I have to choose the bolts with their part number while when I import them with the content center, I have all set the key values.
One of my parts had "Invalid origin/axis" problems and I got all my visible aketches fixed. But I have what I call "ghost" sketches left from bolted connection updates, erasures etc. I can get rid of the visible points but cannot access the sketches to erase them.
The red + sign showing irritates me and I want rid of it.
I have attached the file, 2014 version, some of the adaptive features may not come thru or they may work better on another computer, who would know.
Adding of a single bolted connection using design accelerator is painfully slow, each command is taking up to 3 minutes? It's in Inventor 2012 by the way

It doesn't change to match the diameter of the hole (which is a hole feature in both parts) and it doesn't bring up a list of fasteners. Everything is still highlighted in the assembly. It just won't do anything with it.

I'm currently creating a program to replace all fasteners in an assembly with there Metric / Imperial opposites. My program works and I've created a log file for any issues that do come up.
My question now is:
Is there any way to manipulate bolted connections through the API? Or is this not supported yet?
I cannot seem to find anything to do with them. It's strange though as my program creates an error log for the Lock Washers in the Bolted Connection (which it was struggling with previously anyways), but shows the other fasteners as being successful.
I am using the calculation tab in the bolted connection generator. Is the maximal tangent force (Ft) the total force of plates in shear or per fastener? It appears to be the total force because changing the number of bolts changes the results.
I have been running different configurations due to a failure in a test cell and the numbers don’t seem correct. The calculation indicates that the fastener would fail at a much lower force than it actually is.
I having a stroke or something. I could swear I have used a work plane for a termination plane before in a Bolted Connection. Tried it just now and can't pick the work plane.

When I use the DA to generate a bolted joint that utilizes flat head cap screws (English, 82 deg), the countersunk hole is not large enough and it leaves the heads sticking out slightly proud of the surface. Most of the time when I use FHCS fasteners, the heads must be below flush.
I went into the Clearance.xls file and increased the diameter values for the 82 degree holes. However, it doesn't appear that the DA actually pulls its hole data from this file. I saved the XLS file, closed it, closed IV, retarted IV, deleted the old DA assembly and started over. And I still got the same undersized hole.
However, I did verify that if I just place a HOLE on that point and set the hole as countersunk and clearance for that size of fastener, it will use the hole size that I specified in Clearance.xls.

Bolted connection, clevis pin and bearing are all not working for me. I can go through the steps of selecting the start plane and then the circular reference and the termination point. That is all successful but the bolt doesn't appear, whether I use a clevis pin or a bearing, I get the same result.
Working with sheet metal or FrameMaker all work fine. My content center shows all the bolts, clevis pins and bearings. The content center seems to be working fine. I'm using inventor 2011.
