Hi all, I have a few questions regarding the shapeways API. I already asked Shapeways Eindhoven (it's in coop-mode with them), they told me to also post it on the forum. For those of you who don't know what I am creating: I'm creating an application wich will be available on shapeways in the near future. It leveradges a certain formula to let users create their own models; models that are allways printable. So here it goes: Login: Currently I am logging in as the applications' (*my own) account. I also send an application id (*'supershapes') When I upload the model I have to use the session_id returned from this login. Should I login as the application or should I make the user login? Materials: As I mentioned before in a previous post, but for complete overview: When I get the materials from the api, the color comes in like: <base_color xsi:nil="true"/> Can this be fixed so that I can show the right colors on the model? Price: When calling the getprice method, I should send to shapeways the volume of the model. Shapeways has already a method implemented in the site to do this. Is it possible to get a code-snippet so that the price shown in my application on shapeways is almost exactly the same as shown on shapeways later on? I want to show the price beforehand, because when the user is going to the order page, the flash is closed and the user can't go back to his/her model. Upload with MaterialID: When uploading a model I can't send in a material_ID. Can this be added? After uploading a model I want a user to order his model with a certain material, from which he/she already agreed on the size and pricing, which requires me to send in a material chosen for the model Upload Model Check: After model upload shapeways performs certain checks on the model to ensure model integrity. This check takes a few minutes for my high-res models, which I would like to omit for the end-users' sake. Can this check be avoided in some way? (for example using my application id?) I already build these models programmaticly, so they are allways printable, and before going live the program will be tested accordingly. Order: When a user has completed the flashprogram and uploaded it's model with a certain size and material, he/she would like to order it. In the current situation the model is uploaded into his/her store. Can the model be uploaded to the supershapes store, and the user be redirected directly to the order-page of the model, by using for example the session-id (or the model-upload_id, gotten from the upload)? I hope to get some clarity through this... Kind Regards, Sjoerd van den Berg.
