    file types

    David Antanavige

      Is there a reference somewhere that shows what all the files types created by SolidWorks? This would include all the settings files and template files. (.sldprt, .prtdot etc)

          Not sure if this is what your looking for but if you open a file and hit "file" then "save as" under save as type at the bottom if you select the down arrow SW will list all the file types available. Tom

              Sorry, I'm not aware of one.  There are definitely quite a number of them.  I think almost all of them (except partdot, asmdot, and drwdot) start with sld. - sldlfp, sldbomtbt, slddrt, sldfvt, etc.


              Here's an idea... Maybe a stupid one.


              Look at all of the command line switches for the dir command.  Formulate a dir command that will output a list of all *.sld* files to a text file.  Then open in excel and use Excel functions to strip all the extensions into a column.  Then do AutoFilter on that column and you'll get a list of all the extensions that start with .sld

                Have to look them up under their headings.


                drawing templates


                Document Templates

                Templates are part, drawing, and assembly documents that include user-defined parameters and are the basis for new documents.

                You can maintain many different document templates. For example, you can create:

                •   A document template using millimeters and another template using inches 
                • A document template using ANSI and another template using ISO dimensioning standard

                • A template for detached drawings

                You can organize and access your document templates by placing them on different tabs in the Advanced display of the New SolidWorks Document dialog box.

                Templates can include settings for such Document Properties as:

                •   grid spacing 
                • extension line and break line gap

                • balloon bent leader length

                • text scale and text display size

                • material density

                To create a template:

                1.   Click New art\NEWFILE.gif (Standard toolbar) or File, New
                2. Double-click the type of template that you want to create: Part, Assembly, or Drawing.

                3. Click Options (Standard toolbar) or Tools, Options.

                4. On the Document Properties tab, select options to customize your new document template, then click OK.

                  Only options on the Document Properties tab are saved in a document template.

                5. Click File, Save As.

                6. Select a template type for Save as type:

                •   Part Templates (*.prtdot
                • Assembly Templates (*.asmdot)

                • Drawing Templates (*.drwdot)

                1.   Type a name for File name
                2. Browse to a folder, then click Save.

                sheet formates


                Saving Sheet Formats

                To save the sheet format:

                1.   Click File, Save Sheet Format
                2. Edit File name.

                You can overwrite standard formats or create custom formats. Sheet format files have extension .slddrt and are located in <install_dir>\solidworks\data.

                1.   Click Save.

                Custom properties in the document are saved with the sheet format and added to any new documents that use the format.

                and of course the 3 main ones


                Types of Files

                In SolidWorks, you can open any number of part, assembly, or drawing documents at the same time:


                •   Part (.sldprt)

                •   Assembly (.sldasm)

                •   Drawing (.slddrw)

                SolidWorks gives the three basic file types their own extensions to facilitate finding and filtering files based on content.

                From an active document, you can open related files as follows:

                •   Open a drawing from its associated part or assembly document 
                • Open a part or assembly document from a drawing view

                • Open a part from the component in its assembly document

                Typically, you begin in a part document, creating a part. When you have several parts, you can assemble them in an assembly document. You can create drawings from both parts and assemblies.



                and library features


                Creating a Library Feature

                To create a library feature, you first create a base feature to which you add the features that you want included in the library feature. Library features have the .sldlfp extension. The way you build a library feature affects how you do the following:

                •   Position the library feature on a model. 
                • Edit the position of the library feature.

                As you build the library feature, you can decide to include or to exclude references.

                You cannot create sheet metal parts, weldments, or molds, and save these as library features.


                To create a library feature that includes references , you need to dimension the library feature relative to the base part on which you create it. References create dimensions used to position the library feature (*.sldlfp) on the model (*.sldprt).

                Library features with face references such as fillets do not need reference dimensions.

                You can also create references using relations. For example, if you align the center of an arc horizontally, vertically, or coincident to the sketch origin, a reference is created.


                To create a library feature without references, create the library feature without dimensions or relations relative to the base part. Instead of using references to position the library feature on the model, you edit the library feature sketch and position that sketch relative to the model.

                You cannot create a library feature part (*.sldlfp file) from a multibody part document.
