The Excel file must be in a specific format to be imported. The column names and order must be as shown below. If it's not, you'll get an error message

Offcuts can create this file for you by opening an existing project and clicking on the "Export to Excel" button.

The values for length, width and height must match the settings. If the settings of Offcuts are for decimal inches, the values inside the Excel file must also be in decimal inches.


The validation dialog allows you to correct any issues that need to be fixed before the file can be imported into Offcuts.

To find any problems, look for a warning icon in the left-most column.


  • Description is required
  • Group can be blank
  • The material type must contain material that's contained in the inventory database
  • Quantity must be greater than zero
  • Length, width and Thickness must be valid numbers, and format must match Offcut's current settings. Don't include units like cm, mm or " with the value
  • Ignore Grain must be yes or no

The validation dialog only performs a preliminary validation on the file, in short, making sure the values are valid. Once imported, the parts screen will indicate if any part doesn't fit within the selected material.


You can change any value within the validation screen by double-clicking on a row.

To cancel editing, click on the 'x' button.

To accept the changes, click outside the row or press the Import button.

What are Assembly Groups

When you have a project comprised of several parts, just the part's name may not give you a good indication of where or how the piece is used. For example, assume we have a bookcase that contains 76 parts. Which parts are for the frame? Which are for the drawers? How about the doors? This is where Assembly Groups help.

Assembly Groups allow you to organize your parts into groups, making it easier for you to visualize your project. Using the example above, we can create an assembly group for Frame, one for Drawers and a final one for Doors. When parts are added or modified, we can assign each piece to a group. Of the 76 parts used in the project, the Frame group would have 34 parts, Drawers having 18 parts, and Doors having 24 parts.

Assembly Groups are not only useful for the parts list. When you look at each of the cut lists, assembly groups will color-code each part, making it a breeze to see where the parts are used.


There are two ways to create an Assembly Group.

Method #1

While in the Parts dialog, type the name of the group. The edit box will match what you're typing with known groups as you type the name. If the group you entered doesn't exist, Offcuts will create it.

Method #2

Click on the Groups button and select the Add Group button. Type in the name and press the checkmark button.


You can change the name of a group or delete a group by clicking on the Group button, selecting the group you want to edit or delete and pressing the appropriate button.

Assign a part to a group

While in the Parts dialog, type the name of the group. The edit box will match what you're typing with known groups as you type the name. If the group you entered doesn't exist, Offcuts will create it.

Project Parts

The Part screen is where you enter the parts for your project.

Add a part

Click on the Add button

Edit a part

To change an existing part, either double click on the part, or select the part, and click the Edit button on the toolbar.

Bulk Edit/Delete

You can edit or delete multiple parts at one time by shift-clicking and/or ctrl-clicking on individual parts.

To delete selected parts, just click on the the Delete button

When you edit multiple parts, the description cannot be changed as this must remain unique. If the selected parts share the same values, the dialog will show the shared values. If the values are different, the edit controls will be blank. In this example, Length and Width aren't shown as the values are different for each part.

In this example, we want the selected parts to use plywood that's .25 inches thick and to ignore the grain direction.

The three parts now reflect the changes we've made. A faster way of editing/delete of multiple parts.

Duplicating parts

Select the part you want to copy and click on the Duplicate button

Deleting parts

Select the part you want to delete and click on the Delete button

Sorting Columns

Click on the column heading to sort. Tap multiple times for ascending, descending or natural order.

Renumber Parts

In the following example, the parts aren't in sequential order. This can be caused by parts being deleted or parts being reassigned to a different group. To renumber parts, click on the Renumber button.

What is Ignore Grain?

Not all parts in your project need to follow the grain direction. By Selecting Ignore Grain, you allow Offcuts to try and rotate the part when it generates a cutting list. The result may produce a more optimized layout, minimize waste.

What is the warning icon and why are the length and width red?

You can get the warning icon and red text when Offcuts can't find any material in the inventory large enough to cut from.

Check the inventory tab, make sure the material still exists, and add a large enough size to cut the parts from.


Inventory is where you define the supplies for each of your projects. The Inventory is broken down into three major categories:

  1. Sheet Goods. This is rectangular material. For a woodworker, this would be plywood. However, you're not limited to just one type of material. You can create other materials such as Glass, Metal or fabric.
  2. Lumber. Offcuts works with dimensioned lumber, not rough-cut nor parts that are to be resawn from each piece.
  3. Other Items. A project isn't just made up of material that you mill out. You may need to consider and price items like Hinges, Glue or labour. These items fall into the other category.

You can add and remove items inventory at your leisure. If the material you need isn't in stock, add it.

Not all of us have an unlimited amount of material at our disposal. For each item in the list, you can define how much of that material you have available. Offcuts will do its best to make use of all available items in stock.

Inventory items are shared between all projects. If you delete an item from inventory used by another project, you may cause the other projects to have a part that can't be placed when creating a cut list.


When you install Offcuts, a small number of materials are included in the inventory. Depending on your project, the material or sizes of these stock items may not exist.

To show you how to add material, let's take a project that requires pine plywood. In this example, pine plywood doesn't exist in Offcuts, so we need to add it first.

  1. Make sure the Sheet Goods button is selected
  2. Click on the Materials Types button
  3. Click on the Add New Material button
  4. Enter 'Pine' and click on the checkmark button

Now that the material is in offcuts, we can add the sizes.

  1. Make sure the Sheet Goods button is selected
  2. Click on the Add button
  3. Select 'Pine' as the material type and enter size. Price and Vendor are optional though pricing information will help you understand the project's total cost.
  4. Quantity is the number of sheets you have available to you. Offcuts do not maintain this number. If this material isn't available, enter zero, and Offcuts will not use it when calculating the cut list.

Edit inventory

You can double-click on the item to edit or select the item and click the Edit button on the toolbar..

All projects share offcuts inventory. When you modify the inventory, it affects all projects. If Offcuts determines that the stock item you're adjusting is in use, it will not allow all attributes to be changed.

Amount of material available

Most of us don't have an unlimited amount of wood to cut from. You may have only one 4x8 sheet of plywood but multiple 4x4 sheets. In Offcuts, you can tell it how much material you have, and Offcuts will work through your inventory making the best use of the inventory levels you have.

In the following example for 1/4 inch Baltic Birch plywood, we don't have any 4'x8' sheets in inventory and only one 4'x4' and ten 4'x2' sheets. When Offcuts calculates the cut list, it will ignore the 4'x8' sheet and only use one 4'x4' before moving on to the 4'x2' sheets. If Offcuts runs out of materials to cut from, a warning message is displayed on the cut list screen.

It's important to note, Offcuts DOES NOT maintain inventory levels for you. This is a manual process left up to you to manage.

To adjust inventory levels, double-tap on the selected stock item, adjust Quantity, and press save

Generating Cut lists

Warning Icon

The warning icon will be displayed when Offcuts cannot generate a cut list for all your parts.

To see what parts were not able to be placed, click on the Warning icon.

The list will display all the parts and the reasons. In this example, there were two problems. I ran out of material, and a piece is too large for the material I have available.

The Inventory screen will show that I don't have enough material available for my project. Once I increase the quantity, the error will go away.

The Parts screen will show that I made an error when entering the width of the part. Instead of 116 5/8 inches wide, it should have been 16 5/8 inches. Once fixed, the error will go away fitting the available material.
