Model Object node Bolt selection

Grasshopper Tekla
1

Hi All

Is there a way to select bolts only as "Model Object " node not allowing multiple selection mode?

Problem i have is that i have to select all objects to be able to extract bolts but it takes forever to do.

Can any one explain me this behaviour where single bolts can be selected but not multiple ?

Thanks in advance

I can select bolts, no issues at all.

I guess if you have the bolts in a component you need to toggle objects in components to be able to select them

Hi Oskar,

Thanks for your time.

Yes it can be selected by clicking each bolt separate but not using selection window.

Is you use selection window its not working as clicking through 1000s of bolts its not really officiant. Swipe window works well with parts but not bolts.

Hey mate,

Try using the Geometry Pipeline to grab the bolts. You can also create a filter in Tekla and input the name of that into the “F” input.

@sebastian.lindholm is there a reason why we can’t box select bolt with the Tekla Model Object component?

Hi,

Not being able to area select bolts when activated this way seems to be an API limitation (or bug I guess…), nothing we can do about it in the near term I’m afraid.

The Geometry pipeline is a good alternative, another one would be to area select certain parts and extract bolts from them. That can be done in the following way:

  1. Area select objects, get their children and filter out the bolt groups:

  2. At this stage we might have duplicated groups if we’ve selected both the main and secondary parts, as they would return the same bolt groups. So the next step is to filter out duplicates based on their ID:

Here’s the above definition in a cluster:

How efficient this is would depend on how big the are selection is and the ratio of model objects to bolts.
