AutoDrop issues

[Ivan_Sinicyn]

I was very happy about the fastener insert lock button in version 2032.2, but today I discovered that the button is missing when inserting countersunk fasteners. Is that how it was intended? I also noticed that if you insert fasteners with the "follow pattern" function, then you can grab the fastener to rotate the pattern around the axis. What's the point?

Hi! This looks like a bug to me. Please share the files here. I would like to understand the AutoDrop behavior better.

Many thanks!

I have added files. But it is difficult to understand from the finished file, you need to recreate the operation again.

Works the same for me.  With countersunk (flat head) screws, Autodrop does not show the lock rotation button.  And, when using Follow Pattern, the whole pattern can be dragged around the primary member-- but it snaps right back where it belongs when it is released, so that doesn't seem like a real problem. 

But the lack of a rotation lock control appears to be a bug.  I can't imagine a good reason for leaving it out.

Good find.

The follow pattern does not pattern the constraints like it does with Autodrop, so the pattern can rotate around the initial fastener. 

[Ivan_Sinicyn]

And you can apply "constraint" to it. (screenshot)

Maybe that makes some sense.

And one more thing. If you make a classic pattern by "Feature pattern select", then all elements will be blocked.

Hello guys,

1. Constraints: You are right, Follow Pattern does create iMate on first / master bolt only, but pattern as feature / group keeps its position. As was said above, you can rotate entire pattern but once you release rotating bolts pattern, bolts pattern jump to correct / original position

2. Lock Rotation: It depends what bolt type you are placing / AutoDroping. If you place "regular" bolt like DIN 6921 that has regular head then under head there is created iMate of type INSERT. This INSERT type has option LOCK ROTATION.

While placing countersunk bolt like DIN 7991, usually being placed into countersink hole, creates iMate type MATE (conical face to conical face). MATE does not support lock rotation. It is iMates types Inventor naturality.

Thanks for the reply.

Well, I'll have to keep inserting thousands of countersunk screws manually through the insertion function with a turn lock. One by one. One by one. One by one.🤖

Curious, why does it matter if they can turn?

[Ivan_Sinicyn]

I don't know how it happens, but very often the screws somehow turn by themselves. It looks very bad on the drawings, I don't like it. It's easier for me to put them in manually than to correct each one later.

I see, that's fair. 
I would say that having them not aligned would be more realistic as far as the drawing goes though, in real life the screw heads would never be aligned.

It would be nice to have the option though.

Sometimes several screws are on the same axis. You create a drawing and see it! I'm shaking from this mess.🤣

I thought I was quite pedantic when it came to straight lines and things lining up, but I have never seen this 😄

[jan_priban]

I see, could "ground" help somehow?

In this case, the entire adjoining node is blocked. How to keep working if you have a bunch of blocked parts hanging in the air? Even if I insert fasteners at the very last moment, I always have to redo something in the process. This, in turn, will cause a bunch of errors. In my "assemblies" always only the base part is locked at the origin.

I tried to modify family template of the DIN 7991 to define INSERT iMate (that allows to LOCK rotation degree of freedom) but it does not work as I expected - I can replace family template but such template breaks AutoDrop functionality, means Place from Content Center works like when AutoDrop is switched off (even AutoDrop is On). So sorry, I have no workaround / suggestion how to lock rotation for countersunk bolt.
