STL Import for CoCreate Modeling

Over the weekend I started fiddling around with CoCreate Modeling’s SDK and today I think I have my first add-in product for CoCreate Modeling. I say “I think” because its not been tested yet. I just put together an installer and uploaded it to Note that the installer does not automatically load the add-in into CoCreate Modeling. You need to load it manually for which detailed instructions are given in the ReadMe.txt file.

There is a reason why I am mentioning this here. Before we officially release this product along with other CoCreate Modeling add-ins that we have planned, I want to know which versions of CoCreate does this add-in work with. I have CoCreate Modeling 17.0 and I built the add-in using the SDK that came with it. But I suspect that the add-in will work with previous versions of CoCreate Modeling as well. Exactly which, I don’t know and that is what I hope some of you will help me figure out. If you are running an older version of CoCreate Modeling I would appreciate it if you could download and try the add-in and let me know whether it loaded and worked properly. If you have version 17.0 then I would appreciate it if you could test it for me.

A little about the add-in itself. Its pretty straightforward actually. As the name suggests STL Import for CoCreate Modeling is a Stereolithtography STL file import add-in for CoCreate Modeling. It gives CoCreate Modeling the ability to read STL files. As it stands, CoCreate Modeling can only write out STL files. The add-in converts the mesh object stored in the STL file into a 3D solid in CoCreate Modeling, which can be edited just like how you would edit a normal solid.

Once loaded into CoCreate Modeling, the add-in adds a new section in the Add-ins task panel called “STL Import for CoCreate Modeling“. This section houses four command buttons: Import, Help, Register and About.

Clicking Import prompts you to select a STL file which the add-in imports it into the active document. In case you do not have STL files, a couple of sample STL files are copied into the Samples folder for you to test the add-in.

    Fantastic Deelip. I will try it out. Will it run on 64bit?

  • Not sure. Starting this morning, my dedicated software testing team [of two ;-)] is going to put this add-in through hell.

    Hi Deelip,

    I've tried to load the addin into v17 64bit on a windows 7 system and i'm getting the error:
    Activation of module “STL Import for CoCreate Modeling” failed: “Add-in not registered.”
    Any suggestions?

  • I have written the 32 bit version of the add-in. I hope to write the 64 bit version shortly. Sorry for not mentioning this in the post.

    For those of us who don't understand all this programming stuff could you answer a question. If you can write an add-in like this in a couple of days why can't software packages like CoCreate and others include this type of functionality?

    Just curious

  • Well actually, our data exchange technologies are wrapped up in libraries (DLL's) which have been designed, developed, updated, tweaked and tested over years. All that I needed to do was create a CoCreate Modelling add-in using the template provided by PTC and find a way to call the relevant functions and classes of our DLLs in it.

    I tried to request a trial license key for the CoCreate STL Import command and I keep getting an error saying unable to connect to server. I have an internet connection. ANy ideas what the problem is?

  • Can you send me a screenshot of the SYCODE License Server dialog box? Email to deelip (at) sycode (dot) com

    THis add in would solve many of my problems. The only thing is that I can’t install it. The link to the files points me to one exe file. There is no txt or installing guide. Could you please tell me where to find it?

    Can this work with CoCreate 18 (now called Creo Elements Direct 18)?  I would like to know how it can work and if so, the requirements.
    -Thanks, Michelle
