![]() Double-click the new Spreadsheet object in the tree view.Now, lt's extract some information about these objects.Edit their Placement property (or use the Draft Move tool) to space them out, so we can see the effects of our changes:.Start by switching to the Part Workbench, and create a couple of objects: a box, a cylinder and a sphere.We will assume the reader has worked through the previous chapters and we'll not provide a lot of detail that's been covered previously Reading properties In the following example, we will create a couple of objects, retrieve some of their properties in a spreadsheet, then use the spreadsheet to directly drive properties of other objects. That would make the spreadsheet and the object depending on each other. There is only one thing to keep in mind, as FreeCAD prohibits circular dependencies between objects, a same spreadsheet cannot be used to set a property of an object and at the same time retrieve a property value from the same object. This turns spreadsheets into powerful control structures, where the values inserted in specific cells can drive dimensions of the model. In FreeCAD, however, spreadsheets have an additional utility: Their cells can receive a name, and can then be referenced by any field supported by the expressions engine. Spreadsheets can be exported as CSV files, which can be imported in any other spreadsheet application. These spreadsheets can then be populated with data extracted from your model, and can also perform a series of calculations between values. This workbench allows you to create spreadsheets such as those made with Excel or LibreOffice directly in FreeCAD. FreeCAD features another interesting workbench to explore: the Spreadsheet Workbench.
