===============================
@tableofcontents
The new algorithm of Boolean operations avoids a large number of weak points and limitations presented in the old boolean operation algorithm.
-@subsubsection occt_draw_7_7_1 bop, bopfuse, bopcut, boptuc, bopcommon,
+@subsubsection occt_draw_7_7_1 bparallelmode
+
+* **bparallelmode** enable or disable parallel mode for boolean operations. Sequential computing is used by default.
+
+Syntax:
+~~~~~
+bparallelmode [1/0]
+
+~~~~~
+
+Without arguments, bparallelmode shows current state of parallel mode for boolean operations.
+
+* *0* Disable parallel mode,
+* *1* Enable parallel mode
+
+**Example:**
+~~~~~
+# Enable parallel mode for boolean operations.
+bparallelmode 1
+
+# Show state of parallel mode for boolean operations.
+bparallelmode
+~~~~~
+
+@subsubsection occt_draw_7_7_2 bop, bopfuse, bopcut, boptuc, bopcommon
* **bop** defines *shape1* and *shape2* subject to ulterior Boolean operations
* **bopfuse** creates a new shape by a boolean operation on two existing shapes. The new shape contains both originals intact.
