Descriere

Coutout tool creates a cutout in a walled object (e.g., a pipe) to fit another walled object.

The Part JoinCutout tool creates a cutout in a walled object (e.g. a pipe) to fit another walled object.

Usage

How to use

  1. Select the base object first, then the object to define the cutout.
    The order of selection is important. It is enough to select one sub-shape of each object (e.g., faces).
  2. Invoke the Part JoinCutout command.

Properties

Base

Properties

Base

  • DateBase: Reference to base object (the one to make the cutout in). The object should be a single solid.
  • DateTool: Reference to tool object (the object that is to fit into the cutout). The object can be a single solid, or a valid compound of solids.
  • DateMode: The mode of operation, equals 'Cutout' (Changing that will transform the tool into another Part_JoinXXX). The value of 'bypass' can be used to temporarily disable the long computations (a compound of Base and Tool will be created, which is a fast operation).
  • DateRefine: Sets whether to apply Refine operation or not, to the final shape. The default value is determined by a 'Automatically refine shape after boolean operation' checkbox in PartDesign preferences. When Mode property is 'bypass', Refine is ignored (never applied).

Example

Examplu

  1. Create a pipe by applying thickness to a cylinder:
  2. Create another, smaller diameter pipe, and place it so that it pierces the wall of the first pipe:
  3. Select the first pipe, then the second pipe (order of selection is important), and click the 'Cutout for object' option from the Join tools dropdown toolbar button.

Algorithm

Algoritm

Algoritmii din spatele instrumentelor de conectare sunt destul de simple, iar înțelegerea acestora este importantă pentru utilizarea corectă a instrumentelor.

1. Base object is boolean-cut with Tool object. The resulting shape is a set (compound) of non-intersecting solids (typically, two).

2. The resulting compound is filtered: only the largest solid is kept.

3. If Refine property is true, the resulting shape is refined.

Notes

Notă

  • Dacă după pasul 1, obiectul rămâne într-o singură bucată, rezultatul Cutout va fi echivalent cu boolean cut al Base with Tool.
  • Now, the tool will produce unexpected result, if a compound is supplied as Base. This may be changed in the future.
  • Because the largest piece is determined by comparing volumes of pieces, the tool can only work with solids. This may be changed in the future.

Programare-Script

Instrumentul Join poate fi utilizat în macros și de la consola python utilizând umătoarea funcție: 

JoinFeatures.makePartJoinFeature(name = 'Cutout', mode = 'Cutout')

Exempluː 

import JoinFeatures
j = JoinFeatures.makePartJoinFeature(name = 'Cutout', mode = 'Cutout' )
j.Base = FreeCADGui.Selection.getSelection()[0]
j.Tool = FreeCADGui.Selection.getSelection()[1]

Instrumentul propriu-zis este implementat în Python, vezi /Mod/Part/JoinFeatures.py unde este instalat FreeCAD.
