Blender is a modelling and animation 3D software with GNU General Public License (GPL). Boolean operations are a useful tool for modelling. Previous implementations of Blender Boolean operations have some drawbacks and the Blender users are not totally satisfied with them. The proposed implementation avoids the existing drawbacks of previous implementations and helps users in their modelling stage.Categories and Subject Descriptors (according to ACM CCS): I.3.4 [Computer Graphics]: Graphics Utilities I.3.5 [Computer Graphics]: Computational Geometry and Object Modelling I.3.6 [Computer Graphics]: Methodology and Techniques
