How to convert stl porous structure into IGES format

By Future Dynamics on 28 Mar 14:27 16 answers 3 comments

Hi, I have model in stl fomat, I want to open this model in abaqus, therefore I need to convert this model into iges format. Please attach find the model.

please guide if someone know, I really appreciate for the help

    I was able to convert this for you. I do not know how to convert the file in your software but I use Autodesk Inventor and was able to convert the file type easily.

    Hey Jonathan,

    ABAQUS say file cannot read, it may be corrputed or not a valid IGES File. can you please fix the problem.

    I'll try again. Just realized I couldn't open it either.

    Future,
    I have a model you can try, but every time I try to attach it here the website barfs. It is a 135 Mb Zip file.
    There are a few gaps in it that did not get surfaced correctly, but they are very small portions that you may be able to repair.
    I'm able to import this iges file into SolidWorks, but it takes forever to do anything to it.
    Let me know if you have another means that I can send the file to you. I assume it is too large for most email systems. Maybe an FTP, or DropBox like system?

    The blue lines indicate gaps in the surface structure.

    thanks fred for the effort, can you please send to me the file through dropbox.
    I will be really appreacite

    Fred I have an idea, if the whole model takes time, you can cut the model into four parts, and you can convert just one quarter of the model, I also did partition of model in netfabb software. please attached find the model.But I am not sure if the partitiong os okay for the conversion, Please have a look on it.
    I look forward for the fruitful discussion

    Future,
    I', not sure how to send a file through Dropbox to your email account, but see if this link works for you:

    Slicing the model into quadrants would have likely made the conversion go faster, but I didn't know it was symmetrical at the time. At least any repairs can be minimized by picking the best quadrant to work with.

    Let me know how it works.

    fred I downloaded the file, now I am running in abaqus as well as autodesk simulation mechanical. but its buffering and still continue. I don't know how much time it need more to become visible.I will let you know the status as soon as model open

    hey fred, autodesk mechanical simulation said file aborted, now I am waiting fro abaqus answer

    No problem. The file is very complex, and it took several hours for Design X to fit a surface over the mesh data.

    could you please tell me the procedure and which software you used for the conversion, I will try to do for quadrant model, as you know full model is taking so much time.

  • FredSWUG

    I imported your STL file into Design X (Formerly RapidForm).
    The Autosurface tool was used to form a surface over the STL mesh data (this took a long time).
    The resulting surface data was exported as an IGES file.

    SolidWorks and other CAD programs will open the surface data now. There are some missing spots, as seen in my screenshot above, but the majority of the model is there.
    To reduce calculation and repair time, I'd try cutting the model into quadrants like you suggested. Once the best looking quadrant is identified, it can be repaired and mirrored.
    I'll take another look at the file as soon as I can, but I've got some other projects to work on first.

    Well the full model is still running, I am waiting.
    Please when you find sometime have a look on quadrant model.
    I will let you know the status of full model if its working or not.
    Thanks again for the generous guidance and effort you have shown in my cad file

    Hi Fred good morning, full model is still running, however I am wondering in the last if I get aborted or error. you are right, It is consuming a lot of time; I am sorry to say but if you have some free time. Can you please have a look on quadrant model?
    I would be really appreciating for the help.

    anyway I am sending you the file attached with this message Please have a look on it.
