Introduction

The dimensions of the PVC pipes can be found here PVC_Pipe. Wikipedia on Nominal Pipe Size (NPS) [1],

We will use following guide line for position of a pipe: put one end (base) of the pipe onto the x-y plane. The center of the base has coordinate (0,0,0). The the other into positive direction of the z-axis. The default pipe length is 1ft. Rationale: This is the same way FreeCAD places a new cylinder. We mimic the FreeCAD behavior for UI consistancy.


Notations

  • O.D. - outer diameter.
  • Average I.D. - average inner diameter (why average?). This dimensions determine the size of the pipe.
  • Min. Wall - thickness of the pipe wall.
  • Schedule - determines (indirectly) the thickness of the wall.

Notes

"O.D." = "Average I.D."+2"Min. Wall"

How to create a pipe macro

Steps to create GUI: The original instruction are taken from [[2]] but I (Ruslan) have problems to with them.

  1. Create with QT Designer a Dialog based on QDialog class. Save the name for example add-nps-pvc-pipe-dialog.ui
  2. Convert add-nps-pvc-pipe-dialog.ui to python code running
    pyside-uic add-nps-pvc-pipe-dialog.ui -o pipe-dialog.py
  3. Insert content of def setupUi(self, Dialog) and retranslateUi from pipe-dialog.py (How can I insert here a block of python code?)

into your macro file. Note, the intention used in macro files created by FreeCAD and the intention created by pyside-uic are different. You must adjust them.
