The testing function can be started in the toolbar and adds a new test directory in the project tree, within which subordinate elements are available to conduct tests. Specifications can be entered in the tabsheet below. The tool can also be accessed in the Extras menu of the Extras submenu of the context menu of the part.

You can test the quality of fabricated parts regarding their dimensions and other attributes. For the testing of dimensions, measurements conducted with the virtual part in netfabb serve as reference value. So, the testing function allows you to cross-check the measuring results of fabricated parts with measurements conducted in netfabb. Acceptable limits of deviation can be defined for each measured value.

If you right-click on the test, it can be renamed or removed entirely in the context menu. If you want to remove only some subordinate elements, right-click on that specific element and click "Remove".

Create Definition

To be able to get a useful test result, it is important to create a precise definition of the test. In the definition directory of the test in the project tree, all measurings conducted with the part are listed, with single measurements as subordinate elements.

If you click on the "Definition" directory or on a measuring (group of measurements), you can take offsets and scales into account, which are expected to occur during production, and you can specify general standard tolerances. These are acceptable values for deviations in general, measured in mm for distances, ° for angles and % for circle diameters. With the button "Apply", tolerances are calculated according to these values for all single measurements.

The single measuring operations (measuring points) are included into the test if the box next to their name is ticked in the project tree. If you click on the measurement, you can see the reference value, which is based on the measured value and could be modified by the general definitions, and you can insert the upper and lower acceptable value for every measurement. The offset which you have set in the general definition, can be either added or deducted, depending on the option you choose in the dropdown menu. In the text field below, you can add notes for the test of this measuring point.

Add value.pngValues

If you want to test other attributes of the part, click on the Add Value button after selecting the values directory, double-click on the blue Plus next to the directory or right-click on the Values directory and choose "Add Value" in the context menu.

Then, add and specify additional values. You can insert the name of the attribute and choose one of three ways to define the criteria of the value: an exact value, as with measurements, a Yes/No distinction or a choice from several options.

Insert exact value and limits
Yes or No can be defined as correct
Choice from several options. By clicking on the Plus button, options are added. The ticked option is defined as correct

When you click on the test in the project tree, the button "New Test Result" is available. The same is obtained by a double-click on the blue Plus next to the Test directory or in the context menu after right-clicking on the test. The test result is added to the test directory. In the result, you will see which measurement of the real manufactured part is within an acceptable range and which one is not.

In the test result, all measurements and values which are activated in the definition (by ticking the box) are listed. For every measurement and every value, the measured values must be inserted. If these values are within the defined tolerance, the attribute is colored green in the test result. If they are not, it is colored red.

Enter the measured value.
Specify, if the attribute is given
Select the attribute which applies.
