|-
|| '''Slide 1'''

'''Title Slide'''
|| Welcome to this Spoken tutorial on '''Importing an Image into FreeCAD.'''
|-
|| '''Slide 2'''

'''Learning Objectives'''
|| In this tutorial, we will learn to:
* Import an image into '''FreeCAD'''.
* Scale the image using '''Calibrate''' tool and
* Trace the image using the '''polyline''' tool
|-
|| '''Slide 3'''

'''System Requirements'''
|| To record this tutorial, I am using:
* '''Ubuntu Linux OS version 22.04''' and
* '''FreeCAD version 1.0.0'''
|-
|| '''Slide 4'''

'''Prerequisite'''
|| To follow this tutorial,
* Learners should have basic knowledge of the '''FreeCAD''' interface.
|-
|| '''Slide 5'''

'''Code Files'''

The following code files are required to practice this tutorial.
* '''Flange-rod.png'''
* '''Bolt.png'''

These files are provided in the Code Files link of this tutorial page.
|| The following code files are required to practice this tutorial.

These files are provided in the Code Files link of this tutorial page.
|-
|| Right click on the Freecad app image, Select Run.
|| Let’s open the '''FreeCAD''' interface.
|-
|| Click on '''File '''menu select the new option

Go to '''File''' and click '''New'''.
|| Let us open a new file.
|-
|| Click on '''File''' menu, select '''Import.'''
|| Now let’s import a 2D image.

Click on '''File''' and select '''Import.'''
|-
|| '''Import file''' dialog box opens.

Click on the file dialog box and select supported formats
|| '''Import file''' dialog box opens.

Choose the '''Files of Type''' as''' Supported formats'''.
|-
|| Select Image File.
|| Select the '''Flange-rod.png''' file and click '''Open'''.
|-
|| Point to the imported image.
|| The image is imported.
|-
|| Go to navigation gizmo and click on Top view.

Under Model, double click on the '''Flange-rod.'''

'''Image plane settings''' panel opens.
|| To view the image properly, go to navigation '''gizmo''' and click on '''Top''' view.

Under '''Model''', double click on the '''Flange-rod'''.

'''Image plane settings''' panel opens.
|-
|| Highlight the position and rotation.

Highlight the width and height

Highlight the '''Calibrate''' tool.
|| The position and rotation of the image can be changed if required.

The image size can be changed by following ways:
* By entering the width and height manually or
* By using the '''Calibrate''' tool.
|-
|| Click the '''Calibrate''' button

Click and drag the cursor from one point to another.

Display the '''textbox''' where distance is entered.

Enter '''38mm''' in the textbox and point to the distance shown in the image.

Show the image scaled.

Under the Tasks, Click on Ok Button.
|| Now click the '''Calibrate''' button.

On the image, click and drag the cursor from one point to another.

A text box with length in millimeters appears.

Enter the actual distance between two points that is 38mm as shown in the image.

Press '''Enter'''.

This will scale the image proportionately, adjusting both width and height.

Click on '''OK''' to enable the changes.
|-
|| Scroll the mouse to zoom out the image.
|| To see it clearly, scroll the mouse to zoom out the image.
|-
|| Point at the image.

Only narration.

Click on the '''Create sketch''' tool under the '''Part Design Workbench'''.
|| This image can be used as a reference background for sketching.

Now we will trace the image.

Click on the '''Create''' '''sketch''' tool under the '''Part Design '''workbench'''.'''
|-
|| Under the Tasks panel, Select attachment as XY-plane and click OK.
|| Under the '''Tasks''' panel, Select attachment as '''XY-plane''' and click '''OK'''.
|-
|| Cursor near the image.
|| Now let’s trace the image.
|-
|| Click the '''Create polyline tool'''.

Click on all the lines of the image to trace it.

Click on the Dimension dropdown,

Select '''Constrain horizontal distance'''.

Click on the '''horizontal line'''.

An Insert length box appears with the same length. Click OK.

Click on the '''Dimension dropdown''',

Select '''Constrain vertical distance'''.

Click on the vertical line.

An Insert length box appears with the same length. Click OK.
|| Click the '''Create''' '''Polyline''' tool.

Let’s draw all the lines of the image to trace it.

Do you know why we trace images in '''FreeCAD'''?

By tracing we are recreating the shape of the image.

These traced shapes become editable 2D geometry.

Now we have traced the image, let's check the dimension.

Click on the '''Dimension dropdown''',

Select '''Constrain horizontal distance'''.

Click on the horizontal line.

An Insert length box appears with the same length. Click OK.

Similarly we will measure the vertical distance.

Check the length in the insert length box. Click OK.

Notice the dimensions of length and width.

They are scaled as per the image.
|-
|| '''Close''' button on the left panel to complete the sketch.
|| Click the '''Close''' button on the left panel to complete the sketch.
|-
|| Click on the '''eye icon''' symbol to hide the image.

In the left panel beside the name.

Press Space bar to hide or unhide the image.
|| Click the eye icon of the image to hide or unhide the image.

You can also press the '''Spacebar''' to hide or unhide the image'''.'''
|-
|| Enter the '''File''' menu and select the '''Save As '''option.

Enter the name as''' Flange-rod-trace.FCStd''' and click on '''Save'''.

Close the tab at the bottom.
|| Let us now save the file.

Click '''File,''' and select '''Save As.'''

Enter the file name as '''Flange-rod-trace.FCStd''' and click on '''Save'''.

Close the File.
|-
|| Go to '''File''', click on''' Open Recent.'''

Select '''Flange-rod-trace.FCStd''' and click on the '''Open''' button.

Under the Model menu,click on the sketch, and select the Pad tool.
|| Let’s now reopen the saved sketch.

Under the Model menu,click on the sketch.

Select the '''Pad''' tool to convert the sketch into a 3D model.
|-
|| Move the navigation gizmo.
|| The Flange rod is now scaled and traced.

It can be used as a base for building detailed mechanical assemblies.
|-
|| '''Slide 6'''
