컴퓨터 그래픽에서는 수많은 정보를 취급한다. 너무 많아서 개발사마다 또는 개발프로그램마다 필요한 정보만을 취급한다. 필요한 정보는 자신의 정보형식(data format)에 맞추어서 저장되게 된다.
작업을 하다보면 각 프로그램별 우수한 점을 효과적으로 사용할 때가 있다. 이를 위해서는 정보교환이 필수이고, 정보교환을 위해서는 서로의 정보형식을 알아야 한다.
수많은 정보형식에 대하여 일목요연하게 정리해놓은 웹페이지가 있어 여기에 기록한다.
개인적으로는 DXF 파일 형식을 주로 사용하고 있다.
Powerpoint 2007에서 수식편집기를 사용하기가 매우 어렵게 되어 있다.

ANSYS와 CAD에 관한 글을 검색하던 중 아래의 내용을 알게되었습니다.
혹 저자권에 문제가 된다면 바로 삭제하겠습니다.

3D cad 에서 그린 것을 ansys 로 가져오는 것과 관련된 다양한 내용들을
정리했습니다.
질문1. Ansys-autocad interface/translator?
-. The only format is IGES or SAT
-. ANSYS connection for SAT
-. Very poorly and requires extra work to “clean” up your *.sat geometries.
-. Simpler 3D geometries the IGES went OK,
when the geometry was more complex the IGES proved to be poor.
-. The SAT was a little better
질문2. I imported an IGES file to ANSYS5.6, it generate a wireframe model.
-. Try typing the command: /facet after you import the IGES file. For some
reason ANSYS issues the command /facet,wire when you read in an IGES file
질문3. Has anyone any idea of how to get a Patran file into Ansys
-. What I do is change the preferences in Patran to ANSYS.
Then I go to analysis and run Patran.
This creates a *.prp file, that can be read into ANSYS.
Then start up ANSYS and from the Utility menu do File/Read Input From.
질문4. I would like to transfer my ansys fe-model into hypermesh.
-. I have transferred the finite element information from
an ANSYS model into hypermesh by using the unblocked
format with the CDWRITE command.
-. only export the surface mesh, Then you can have H/M create the solids.
질문5. Can anyone tell me if it is possible to mesh a surface in Pro/Mechanica and
import the mesh into ANSYS?
-. Pro/Mechanica will create an *.ans file that can be read into ANSYS.
질문6. Does anybody have an idea where to get a reliable piece of software to
convert 2D DXF models to ANSYS geometry ?
-. 1. Read the dxf file into AUTOCAD
2. Export an IGES file from AUTOCAD
3. Read the IGES file into ANSYS
-. A 3d cad code such as SolidEdge (or any of this ilk, I suppose) can read in
a DFX file and export out either a parasolid (of lines) or iges. Ansys
will read either.
질문7. Does anyone have a know-how to iges solid geometry from ideas to ansys? It
exports from ideas but it cosistently aborts in ansys during import.
-. There is a software called CADFIX will fix your problem. It’ll prepare IGES
file that’s accepted in ANSYS.
질문8. Does anybody knows which are the best setting for CATIA to get models
which could be imported and meshed into ANSYS using ANSYS Connection for CATIA?.
-. In my experience, SolidE components in SHOW/PICK work the best with the
Connection for CATIA product. I’ve had very good luck with it.
질문9. I would like to know if it is possible to import a Nastran model to Ansys.
if it is possible, could you explain me how to import it and the various
difficulties that I can found.
-. A few years ago, I had to turn a nastran model into an ansys model; I used
FEMAP with great success
-. There is no killer translator that works 100%, or for some types of models, even 50%.
FEMAP is the closest you can find out there for such a tool that is available on the market.
질문10. I have tried default IGES to import our CAD models
and at times, it is impossible to fix our CAD using ANSYS
preprocessor tools. So we are in process of evaluating a
preprocessor for ANSYS.
-. You could evaluate CADFIX as a tool for repairing the IGES/STEP files for
import to ANSYS.
-. Have you looked into the Connection Kit for Pro/E? It imports *.prt and
*.asm files directly, without the need to use a neutral file format like
IGES or STEP, so the success rate of bringing in complex assemblies and
parts is much higher.
질문11. does anybody know how to translate ANSYS models (release 6.0)
into NASTRAN models to import into FEMAP 8.0? AND is there a way
to translate output files too?
-. As was already stated, you can CDWRITE to produce a file of ANSYS commands that
can be read into FEMAP. To read ANSYS results, use the command
File/Import/Analysis/Results. You’ll have to specify ANSYS revision 5.x,
because FEMAP does not, as yet, support ANSYS 6.x.
질문12. I am trying to build an equivalent ANSYS FE model from a NASTRAN FE model.
Anybody who has worked on both NASTRAN and as well as ANSYS may suggest me
the equivalent ANSYS element for CBAR (NASTRAN element with corresponding
property PBAR).
-. You can import Nastran model to Patran or FEMAP and then export to ansys
prep7 file – if the Nastran model doesn’t containt Nastran – specific things
like RBE’s, both preprocessors should handle it. In Patran, you have to have
Ansys preference enabled in your license file.

Automatic computation for optimum height planning of apartment buildings to improve solar access
The objective of this
study is to suggest a mathematical model and an optimal algorithm for
determining the height of apartment buildings to satisfy the solar
rights of survey buildings or survey housing units. The objective is
also to develop an automatic computation model for the optimum height of
apartment buildings and then to clarify the performance and expected
effects. To accomplish the objective of this study, the following
procedures were followed:
(2)
A case study on the process of height planning of apartment buildings
will be briefly described and the problems occurring in this process
will then be examined carefully.
(3)
To develop an automatic computation model for height planning of
apartment buildings, geometrical elements forming apartment buildings
are defined by analyzing the geometrical characteristics of apartment
buildings. In addition, design factors and regulations required in
height planning of apartment buildings are investigated. Based on this
knowledge, the methodology and mathematical algorithm to adjust the
height of apartment buildings by automatic computation are suggested and
probable problems and the ways to resolve these problems are discussed.
Finally, the methodology and algorithm for the optimization are
suggested.
(4)
Based on the suggested methodology and mathematical algorithm, the
automatic computation model for optimum height of apartment buildings is
developed and the developed system is verified through the application
of some cases. The effects of the suggested model are then demonstrated
quantitatively and qualitatively.
