Descriere

introduced in version 0.17 Acest instrument permite crearea de țevi/conducte de la zero, sau din obiectele selectate. Obiectele selectate trebui esă fie bzate pe Piese/Part-based (Draft, Sketch, etc..) și să conțină doar un filament deschis.

Cum se folosește

  1. Optional, selectați o formă lineară Part ca de ex o Draft Line, un Draft Wire sau o Sketch deschisă
  2. Apăsați butonul Arch Pipe, sau apăsați în ordine tastele P apoi I

Opțiuni

  • Conductele partajează proprietățile și comportamentele comune tuturor Arch Components

Proprietăți

  • DateLength: Sets the length of this pipe, when it is not based on a wire
  • DateDiameter: The diameter of this pipe, when it is not based on a profile
  • DateBase: The base wire of this pipe, if any
  • DateProfile: The base profile of this pipe. If not given, the pipe is cylindrical.

Fluxul de lucru tipic

  • Start by placing sanitary/hydraulic appliance items (below is an imported step file). You turn these objects into Arch Equipments by selecting them, and pressing the Arch Equipment button.

  • Arch Equipments now have a new SnapPoints property, which is a list of 3D vectors. This allows you to add custom snap points, to which you can snap when the new Draft Special snap button is turned on. Currently that property is only available to python, though. In the case above I added a new snap point at the exit of the wc appliance. The vectors inside SnapPoints appear on the model as white dots:
FreeCAD.ActiveDocument.Equipment.SnapPoints=[FreeCAD.Vector(0,0,100)]

  • With the new "Snap Special" Draft Snap, you can now snap to these custom points:

  • Now we can draw our piping using Draft Lines, Draft Wires, or Sketches. The best way, though, is using only Draft Lines:

  • There is now a new Draft Slope tool that allows to change the slope of Draft lines, to, for example, 5% (0.05). So we can quickly give our waste lines a correct slope. Only z coordinates are change by this tool, so we only need to snap them back to each other, the top projection will stay unchanged.

  • We now only have to select all our lines, and press the Arch Pipe button. Arch Pipe works with any Part-based object that contains one and only one open wire.

  • We can now create connections by selecting 2 or 3 coincident tubes, and press the Arch PipeConnector button. If 3 pipes are selected, two of them must be aligned in order to create a tee element:

  • Schimbarea razei conectorilor nu modifică lungimea liniei de bază subiacente, numai tubul rezultat (prin schimbarea proprietății OffsetStart sau OffsetEnd). Deci, puteți încă să vă trasați linia doar cu linii drepte, fără a fi nevoie să vă îngrijiți de curbele și razele lor.

Este de asemenea posibil să se creeze Arch Pipes fără o linie de bază, în acest caz utilizați proprietatea "Length" pentru a defini lungimea sa.

Scrip-Programare

Instrumentul Pipe poate fi utilizat în macros și de la consola python utilizând următoarele funcții:

import Arch
Arch.makePipe ( [objectsList,diameter] )
