It does not matter which dimension is the thickness so we can also use the height field of the cube for the material thickness. The formulas are entered as we did in part 1 of this series. This would be for example master#p.material. This cube gets then dimensions from the spreadsheet in the format filename, hashtag, table name, dot, variable name. Next we create a new file for each individual board. We save the file with the spreadsheet under the filename master. We covered the creation of spreadsheets and how to install this macro on the last tutorial. We use a macro to create aliases for these numbers so that we can refer to them by name The first step is to create this spreadsheet with all the dimensions.įor the box these are the material thickness, as well as the inner width, height and length. We have a shorter overview article on this toolbox but in this video we will use FreeCAD version 0.19 and slowly go step by step through the assembly process. Notice that positive and negative numbers, as well as filled in and blank cells are allowed.In this tutorial we create step by step an assembly of a Japanese toolbox in FreeCAD. In this example, the sum of 6 cells (A1 to B3) was calculated inside cell B4. Select a range of cells by putting a colon : between the starting and ending cell locations. In a different cell type in: A1+B1 Click off the cell or press enter and your answer appear.Ī1 and B1 must have capitalized letters to work. Spreadsheets can also reference other cells! Type a number into two different cells, in this case I used A1 and B1. If your formula doesn't auto calculate, try putting an = in front of it. Having issues? FreeCAD spreadsheets automatically add equals signs to the start of formulas but occasionally it doesn't work. Right column: same text, but this time without the apostrophe ' Left column: text with an apostrophe ' in front of it. Sometimes it's helpful to type a formula out without it getting calculated, to do this put an apostrophe ' at the beginning of the text. For functions with a () after them, the value you want calculated must be INSIDE the parenthesis. You can do other mathematical functions too such as: sum(), sqrt(), abs(), sin(), cos(), tan(), log(). To force a specific part of a formula to be done first, there must be parenthesis () around it. When putting a formula into FreeCAD, remember that multiplication and division will be calculated first regardless of the order that a formula is typed. You can also do subtraction - division / multiplication * exponent ^ Spreadsheets can also do math! Try inputting "2+2" into a cell, then press Enter. You can edit colors, alignment, and text styling at any time by using the buttons on the ribbon bar above the spreadsheet, or by right clicking on the cell and clicking properties. You can edit it at any time by clicking on the cell you want to edit and going up to the "Contents" or by pressing f2. Just start typing to add text to the selected cell. The spreadsheet is auto saved so you can click the 'X' at any time without losing your work. It will open as another tab at the bottom of your screen, you can switch between the spreadsheet and model tabs anytime you want. Double clicking on it will open the spreadsheet as a new tab, which shows up at the bottom of your screen. Quick Tip: Workbench specific features (such as "Create spreadsheet") are also accessible from the ribbon bar.Ī new spreadsheet will show up in the model tree. To get started, go to the Spreadsheet workbench An introduction to using FreeCAD spreadsheets.
