How to hide and unhide a component or part in an assembly with otk java

Thank you very much for your timely reply.

Although the code is not written in Java, it still inspired me a lot.

In summary, the program goes like this:

• Suppose the part's ComponentPath you want to hide is [40, 43].
• STEP 1 Get the Model of [40], the part's parent.
• STEP 2 Get the ModelItem [43] of Model [40].
• STEP 3 Check if the ModelItem [43] ishidden.
• STEP 4 If true, unhide it; if false, hide it.

In this way, you can switch the hidden status programmtically.

Here I paste the Java Code.

public void OnCommand() throws jxthrowable {
 // STEP 1 Get the Model of [40], the part's parent.
 Model model = session.GetCurrentModel();
 Assembly assembly = (Assembly) model;
 intseq path = intseq.create();
 path.append(40);
 ComponentPath componentPath = pfcAssembly.CreateComponentPath(assembly, path);
 WSolid solid = (WSolid) componentPath.GetLeaf();

 // STEP 2 Get the ModelItem [43] of Model [40].
 WModelItem modelItem = (WModelItem) solid.GetItemById(ModelItemType.ITEM_FEATURE, 43);

 //STEP 3 Check if the ModelItem [43] ishidden.
 //STEP 4 If true, unhide it; if false, hide it.
 if(modelItem.IsHidden()){
 modelItem.Unhide();
 }else {
 modelItem.Hide();
 }
 }​

Thanks again, VladimirN.

Have a good day!😀
