How to import coordinates from Excel

[blahhhh]

I have 3d coordinates from laser scanner. How can I import this into Abaqus to produce a 3d model? I found the guide for Solidworks (see reference below) , but I dont seem to be able to find one for Abaqus.

Could you not inport the coordinates from excel to solidworks and then export the geometry an import this into Abaqus?

 

[blahhhh]

I would, but I dont have access to Solidworks.

Hi, You must write the coordinates according to PYTHON script for each point, can be done in ECXEL, see syntax in the .jnl file.. or .rpy

Look in the Abaqus Scripting User's Manual --> An introduction to .. --> Simple examples --> Creating a part.

This script creates your geometry in CAE.

Just copy paste your list of coordinates in to the script. Maybe you first have to right another script (in Python or Matlab) that creates lists with the necessary brackets and commas.

This might not be the easiest way, but it works....

As portliner menioned, abaqus reads python. Python is simply a coding language and one can just use a text editor to create a python script. Abaqus can generate a 3d model from an IGES file or from the directly coded python script with file extension .inp. unfortunately, simply supplying 3d coordinates is not sufficient as abaqus needs the abilit to interpret how these coordinates are linked together. In a typical .inp there is a modal matrix or matrices that describe the coordinates in space and a element matrix or matrices that describe how the coordinates are linked. There is more information in the .inp like material and cross section info...but you get the fundamental issues that im talking about. You might be able to input the coordinates in solidworks and make a shell with a specified thickness.
