Dear Burak,

Belive me or not, but some of my colleagues use Word or PowerPoint drawing tools for that.

Best regards,

For schematic sketches, you can use inkscape.

One very nice (but complex) alternative is to create real 3D models with blender or a similar software and render those.

Easy free-ware for a 3D look is Sketch-up. I start my drawings there. Only spheres are complicated, so after having drawn separate objects I merge them in Photoshop and add spheres when required.

ChemBioOffice is a nice program to do that. It has some templates to.

How about VMD to view the model, and use Pov-ray to render it?

In MS powerpoint, try using 3D images option. Go to drawing tools>shape effects?3D rotation. this solves some problems, specially for drawing protiens/globules/cells etc.

I use Spartan ... have a look at

The student version of Spartan is not that expensive ... and gives loads of modelling possibilities .. with 3D rotation ... copy ... paste .. and print too.

With 3D glasses ... the old fashioned "Red/Blue" plastic type ... you can even 'see' the model & rotate it in 3D space .... on a standard pc screen ..

Easy to use ... I find Spartan very useful.

Thank u all for the answers. Evaldas, i havent surprised why you do not understand that i need drawing programmes becouse u r not enough to publish at "real journals" (g.e. acs nano).

I suggest using ChemBioDraw. A free trial version is available. Relatively simple to use with nice results!

Use of inkscape software may be helpful in this regard.

It is free vector graphics software available for multiple platform where you can edit any kind of vector graphics content
