Bushing

Hello Alex,

Is this happening with some shipped specification or with the custom one? If this is a custom one, please check that there are no negative values in any fields (COMP_LEN, THD_ENG_M, THD_ENG_R, etc...). Just in case make sure this is not project specific, if no then it could be that some custom ebs files could influence component connection.

I hope this will help.

Regards,

Artiom

Hello Artiom,

Thank you for your help.

It is a custom spec.

There are no negativ values in any field. Please see the screenshot.

There are no ebs files that were changed.

The user set the dimensions specified for ANSI-spec.

How he need to set these dimensions to be displayed properly in the drawing - I do not understand.

Looking forward hearing from you.

Regards,

Alex

Hi Artiom,

I will clarify the question.

Please see the attached files: Spec, Catalog, Model (contains 2 small models).

The only thing that I changed in the catalog was the Comp_Len from 30.988mm to 64mm in the bushing component 2x1 and 2x1/2.

What else do I need to change to make the changed connection to be correct?

Regards,

Hello Alex,

Thank you for additional information, it helped a lot.

I have edited bushing drawing ebs file to meet current requirements. It seems that by default bushing thread engagement should be equal half of the component length (both THD_ENG_R; THD_ENG_M)

Please open  C:\Program Files (x86)\Bentley\Plant V8i\Modules\Base\piping\draw\bushing.ebs and edit  Bushing_draw3D routine.

Sub Bushing_draw3D (compID As At_ComponentID, portPos() As At_Point, viewVec As At_vector)

    Dim CADObj        As Long                '// Graphical CADObjects to be created
   Dim status        As Integer             '// Status code
   Dim pipeOD        As Double              '// Pipe diameter
   Dim engLen        As Double              '// Component length
   Dim port2Dir      As At_Vector           '// Port 1 direction
   Dim flag          As Integer             '// Flag to draw a centerline on hide
   Dim engageLength As Double               '// Engage Lengt added by Artiom 

   status = at_Component_getReal (pipeOD, compID, "PIPE_OD_M")
   status = at_Component_getReal (engLen, compID, "COMP_LEN")
   status = at_Component_getVector (port2Dir, compID, "Port2.Dir")  

   status = at_Component_getReal(engageLength, compID, "Port1.EL")  '// Read engageLength of Port1 added by Artiom
   '\\Call at_Point_translateByVector (portPos(1), portPos(0), port2Dir, engLen/2)
   Call at_Point_translateByVector (portPos(1), portPos(0), port2Dir, engLen-engageLength)     '// Modyfied by Artiom 

   flag = AT_CYLINDER_CENTERLINEONHIDE
   CADObj = at_CADCylinder_create(pipeOD/2, portPos(0), portPos(1), flag) 

End Sub

Please create a back up copy of the original file. I hope this will help. Please let me know the results. 
Kind Regards, 
Artiom 

This helped me a great deal.  Thanks.  

In case some others came across this, I wanted to share a change that I made.

I was not happy with the busing being drawn as the pipe OD.  It simply is incorrect.  In the spec there is a property called FLATS.  This is the dimension across the flats.  I wanted to draw the cylinder that diameter rather than just the pipe OD.

Add this code under  Dim engageLength As Double: 

Dim flatDia       As Double    '// Get Flat dim from spec

Add this code under  status = at_Component_getVector (port2Dir, compID, "Port2.Dir"): 

Status = AT_Component_getReal (flatDia, compID, "FLATS")

Comment out: '//CADObj = at_CADCylinder_create(pipeOD/2, portPos(0), portPos(1), flag)

Add this code: CADObj = at_CADCylinder_create(flatDia/2, portPos(0), portPos(1), flag) '// Read Flat dia for drawing cylinder
