hi,

i am trying to design an architectural structure in cad. it save the path in dwg

how can i convert it into stl file format. or should i just put in cura. i tried importing the file directly into cura but it doesn't read it.

    If your DWG is just 2D lines, you can't make it to STL. 3D DWG also exists, but it might be that you can't convert it to STL either. STL is 3D format, which is made of "surface triangles". You need 3D CAD to make STL files. You can't make them with AutoCad 2D. Surface modeling software are also called CAD software. AutoCad is just one CAD software and in this case.

    Actually, it's very possible to create an STL from almost anything - there's nothing in STL that enforces watertight models, it's just a list of unrelated 3D polygons - hence the market for STL repair tools. It's the model that has to be watertight, not the output format. And obviously, it's easier to create watertight models if the modelling software is designed to do that.

    hi,

    i successfully created an stl file in 3ds max but cura is not uploading that file.

    "Uploading"? Do you mean that it won't load? Is there are error message?

    Can you make the STL available for download from somewhere? Perhaps one of us could tell you what's wrong with it.

    Not in the sense you probably mean. Some 3D design software allows you to import STL, but it will usually be imported as a locked shape, not something you can do complex edits on - scaling is the most you could expect. Basically, the conversion from model to STL is one way.

    not totally true .... spaceclaim can import and modify an STL.

    I did say "usually" and "not ... complex". At best the object will lose all identity, it will just come back as a set of polygons. And, the shape can't have any attributes that STL doesn't know about. Depending on the precise format used there may also be precision problems introduced by using ASCII or single precision STL.

    Hello,

    When Autocad is used here, then it is a matter of the type of objects is used in Autocad. Autocad can modell with objects for solid modelling (see help file). And when they are used, it can export to stl nativly. I have played with that and had no problem to open the file in current cura.

     

    Regards

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
