This article explains how you can use the Tekla Open API to hide and show objects in the model. Note that the API doesn’t provide any direct methods for hiding/showing objects in the model. This article will provide a workaround for achieving this.
Step 1, Add Libraries:
Add reference to the Tekla.Structures.Model library located in the path “C:\Program Files\Tekla Structures\20.0\nt\bin\plugins” and manually open the tekla model. This has been covered in the article below:
Step 2, Manually Create Filter (One Time Only):
You will need to manually create the following filter:
|Object||User field 1 (USER_FIELD_1)||Equals||“Show”|
Note: This step is one time only. Once the filter is created you will be able to use it in all other models.
With the previous filter in place all you need to do is change the value of “user field 1” for the objects in the model, and they will be hidden or shown. For example consider the model below:
Lets say we only want to show the parts in the model. This can be achieved using the code below:
Imports TSM = Tekla.Structures.Model Private Sub ShowPartsOnly() Dim appModel As TSM.Model Dim objModel As TSM.ModelObject Dim objPart As TSM.Part Dim objViewEnum As TSM.UI.ModelViewEnumerator Dim objView As TSM.UI.View appModel = New TSM.Model 'change the user field 1 attribute For Each objModel In appModel.GetModelObjectSelector.GetAllObjects objPart = TryCast(objModel, Tekla.Structures.Model.Part) If IsNothing(objPart) = False Then objPart.SetUserProperty("USER_FIELD_1", "Show") Else objModel.SetUserProperty("USER_FIELD_1", "Hide") End If Next 'change the view filter objViewEnum = TSM.UI.ViewHandler.GetAllViews While objViewEnum.MoveNext objView = objViewEnum.Current objView.ViewFilter = "MyNewFilter" objView.Modify() End While appModel = Nothing objModel = Nothing objPart = Nothing objView = Nothing objViewEnum = Nothing End Sub
Lines 13~20 loop through all the objects in the model. If the object is a part, the “user field 1” attribute is set to “Show”. For all other objects the “user field 1” attribute is set to “Hide”.
Lines 23~28 loop through all the views in the model and change the view filter to “MyNewFilter” which was defined in step 2. By changing the view filters, all objects whos “user field 1” is not set to “show” will be hidden from the model.
