Easy Mesh Modeling
BLENDER
Modeling Commercial & Military Jet Engines
The above meshes were created with a freeware version of BLENDER in just a few steps using the 'Spin' and 'SpinDup' commands. |
STEP 1 |
Start out with a clean 3D screen and add a Mesh >> Circle with 19 Points in TOP VIEW. Scale down the circle on the X-AXIS and delete the selcted vertices. |
STEP 2 |
Stay in Edit Mode and in FRONT VIEW execute the 'Spin' command with the following parameters to create a more solid mesh . |
|
STEP 3 |
Tab out of edit mode and in FRONT VIEW add a Mesh >> Plane scaling the plane as in this example. In TOP VIEW rotate the plane and add a face by selecting all vertices and then SHIFT+F . |
STEP 4 |
This time in FRONT VIEW and in edit mode with all vertices selected execute the 'Spin Dup' command with the following parameters to create the turbine blades. |
STEP 5 |
In TOP VIEW add a Curve>>Nurbs Curve adjust it and convert it to a 'Poly' curve by clicking the apropriate button in the Edit Button Window (F9). Add the other points with CTRL+LeftMouse button. |
Now convert the curve to a 'Bezier' and adjust it as needed. When happy with it convert to a mesh with ALT+C. |
STEP 6 |
In FRONT VIEW in edit mode with all vertices selected execute the spin command with the same parameters as in STEP2. |
That is the commercial turbine jet engine. Now lets do an Afterburner Military engine with a Thrust Vector Nozzle. |
STEP 7 |
In SIDE VIEW add a Mesh>>Plane and reshap it as shown. Look where the object center is. |
In TOP VIEW extrude the mesh to the left with the EKEY. Still in TOP VIEW rotate the mesh and scale it down a little. |
STEP 8 |
In FRONT VIEW execute the 'SPIN DUP' command to duplicate the Thrust Vector Blades using the parameters below. Rescale the vector to your desires. |
STEP 9 |
Add a Mesh>>Plane in TOP VIEW then select and delete ALL vertices (AKEY-XKEY). Using CRTL+LeftMouse add new vertices to draw the profile of the main body for the engine. |
Using the same settings as in STEP2 and STEP6 go into FRONT VIEW and execute the 'Spin' command. WE ARE DONE!! |
So now you see how versatile the Spin and the Spin Duplication techniques are. Add a particle emmiter to the back of the after burner and you can even rotate the thrust vector just like in a real engine! |
