    Try this. Worked fine for me.

    1. Step 1

      Start SolidWorks and click Open.

      Medium

    2. Step 2

      Change file type to STL.

      Medium

    3. Step 3

      Click Options.

      Medium

    4. Step 4

      Change import as to Solid body.

      Medium

    5. Step 5

      Select STL file and click Open.

      Medium

    6. Step 6

      And we have STL file converted into Solid Body.

    Hello every body.
    I have the same problem. I have a STL file of a human body, contains million faceted surfaces, and I want to convert this to a unite surface inorder to use in ICEM ANSYS. I try so many things and now I am really tired of it!!
    please some one help me to overcome this. how can I convert it to a solid body.
    I also try solidwords. but it said: This STL model has two many surfaces.Try to opening with the graphics body option.
    what should I do?
    thanks in advance for your help.

    You can also try some reverse engineering software like Rapidform or Geomagic. But do keep in mind if you intend to use them frequently they do cost a whole lot. If it's just for one project try to get a trial version.

    There is no way to do it with quality. Best way is redrawing it.

    Or you can just try this; (you will probably have empty faces)
    Download MeshLab**. Drag drop the stl file through MeshLab, save as the file .dwg
    Drag drop the .dwg file to Solidworks. The best way again is redrawing the stl file on solidworks.

    I know that SW users will angry with me but i should say it :) If you need it for reverse engineering first get rid of SW. Solidworks have very limited capabilities about working with STL mesh files and reverse engineering. If you want rapid solution Inus technologies can be effective(especially XOR series are very effective). However iam agree with STEF that they are not cheap solutions. If you have just single project that contain stl data and geometry isnt too complex,then Cemal's solution is enough. Also its freeware ( I mean MeshLab) Of course there are some other ways by business plan. For example if we consider you need that conversation ( STL => CAD Type) just for actual project. You can post it to some freelance sites as job posting. So Someone can do it for you with low prices. Just idea

    Ok, it's going to take a few weeks but I guess I don't have a choice.

    I haven't done but you could try opening it in Rhyno changing it to nerbs which if you have less than a certain amount it will work then export it as IGES this then can be imported in solid works (but if it works then the file will be very heavy as each part of the mesh is the equiv. of a loft!!!)
    It should be possible

    If I recall correctly, Solidworks' STL import utility has a maximum of 20k facets. For objects with over 20k facets, I recommend opening the STL in MeshLab as Cemal recommends then exporting or saving as a .dwg file. in Solidworks you must got go file --> open and select the .dwg file extension in the drop down menu. opening will walk you through a wizard. be warned- using this utility to import files into SW is extremely processor and memory intensive. SW will create a plane and sketch for each facet of the dwg file in an attempt to make a part. There are often geometry errors that aren't always fixable within SW. Mine took overnight to import a file with ~40k fascets and i've got an intel i7 with 8Gb ram and a SSD drive. If possible, avoid importing large STL files into SW because it is extremely taxing on your system. SW will crash if you run out of RAM. It can be done, but i recommend using it as a last resort.

    SolidWorks imports an STL file as either a Solid Body or a Graphical object. You cannot add features (Cut, extrude, etc...) to a graphics body. when opening an STL file and the STL extension is selected in the open window, click options* and select solid body.

    How can I save a .dwg file in meshlab? My version (1.3.2) does not give me the choice to export as .dwg and when I force it, I have a "unsupported extension" error.
    I tried to export as DXF but end up with a 2D drawing of the mesh in SW

    i converted an STL with 70k facets using Meshlab. dwg was not a format option, but dxf was. I selected solid model and curves in the dialog. the file came up 20 minutes later as a 76Mb assembly! But it worked.

    Hi, I know Spaceclaim can do this.
