Screw length configuration

Pablo_Manero

Hello! 

I'm creating different documents with screws that we use at the office making some configurations for each metrics and characteristics (length, thread...) but I don't know how to put a determinate option of length for each metric. For example, for metric M4 I have 5,10,15 mm lengths, but for M2 I just want 5 mm length. In this case how can I delete 10 and 15 mm lengths for M2 configuration? 

I know that they are some Onshape libraries for that, but we want to habe the screw properties set before inserting in a new assembly. 

Thanks!

Hello Axel, 

Thank you! I will check the videos.

I also use custom built fasteners.  You can see this document to see how I set up mine.  I am using a configuration variable to drive the length of the screw.  This way, on the fly I can create a length that I didn't think I would need without having to create a new version of the document.  Release management creates a part number for it and everything, for me, stays fairly neat.

I think that this document is so usefull but it's not what I'm looking for. I wanna have the standard length associated with each metric. For example, if I select M2 screw, I will have 3,4,5 and 6 mm options, but if I select the M3 option, I will have 4,5,6 and 7 mm length options.

Why don't you use this featurescript

Hi Dirk,

I want to have a screw properties determinate once I import the part in the assembly and with this feature script I must introduce when I insert the screw. In my assembly are many screws with different characteristics and I don’t want to determinate the properties one by one, so that is the reason why this type of feature script is not useful for me. The other problem I have is that I want to have a configuration which only give me opportunity of introducing the standard screws (metric/length/thread size) and not an imaginary one.

@Pablo_Manero oh I see. I didn't fully absorbed you first post. I am hoping onshape will add the ability to configure configuration inputs.

Yeah I have been missing this functionality too...

The way we handle this is by creating a "master" screw model and derive it into a new part studio for each size (M4, M5, etc...) and create the length table in there.

By doing this way you should still be able to do a "replace" (if you need to change the size) without breaking mates (because the geometry all comes from the same master so faces ID are the same).

Here's an example doc: https://cad.onshape.com/documents/46a326b4a97bd99579866e64/w/98aff52f023b0b23139beb54/e/a699a4775463f98ce0b0d693

Mmmmm... yes, could be a good idea, but we have a lot of types of screws with multiple combinations of metric, length, thread size... with this mode that you tell me, we would have a very big list of part studios to select the screw that you are looking for in the import option...

For other examples I will keep your option in mind!

Thanks Eric!
