The conference is about computer aided design. So the area of simulation and modelling employing the computer technology would be appreciated.
This would be shown clear in the final paper.

It is not normal when a research paper regarding Virtual reality and CAD does not include any figure at all.

The paper is not in the final conference format as well as the references.

References would be reviewed because there is a repitition in some of them like (e.g. NICHOLLS, R.J. AND M. MIMURA, 1998. Regional Issues Raised By Sea-Level Rise And Their Policy Implications. In: Climate Change, 11, 5-18.) is ritten two times
e.g. ZELZENIK, R., HENDRON, K. AND HUGHES, J: 1996. SKETCH: An Interface For Sketching 3D Scenes In: Computer Graphics Annual Conference, ACM. is not included in the text at all.
References , specially journals, are not written in a consistant format (e.g. for articles pages sometimes 319-328, and sometimes pp. 213-234, or Pp. 123-134). For author name sometimes written (Last, First), and sometimes (first name and last name.
