|-
||'''Slide Number 5'''

'''Code Files'''
|| The files used in this tutorial are provided in the code files link.

Please download and extract the files

Make a copy and use them while practising.
|-
|| Using Draft creations tools, draw a pentagon.

Change sides to 5.
|| I have opened '''FreeCAD''' and opened the file provided with this tutorial.

|-
|| Cursor on''' Draft modification tools'''.
|| First let’s mirror the polygon using '''Draft Modification Tools'''.
|-
|| Click on '''pentagon''' and then click on the '''Mirror tool '''in''' Draft modification tools'''.

'''.'''
|| Select the pentagon and click on the Mirror tool as seen.
|-
|| Move cursor to the canvas.

Left click on first point, move the cursor to see the mirror line.
|| Move the cursor to the canvas to draw the mirror angle and direction.

Left click to set the first point and move the cursor to see the mirror line.

In 2 dimensions this will be a line.
|-
|| Select the second point and left click again.
|| I will draw a vertical line on the canvas to set the mirror line.

|-
|| Point to the report view.
|| When a tool is chosen, report view will prompt the user for the next action.

Select the second point and left click again.
|-
|| Cursor on the mirrored pentagon.

Move cursor to show distance.
|| Notice the '''pentagon '''is mirrored.

The mirrored object and the parent are equidistant from the mirror.
|-
||
|| Pause the video and draw a mirror through the object.

Notice the parent and child overlap since they are symmetrically placed.
|-
|| Select the mirrored objects.

Press the '''Delete''' key on the keyboard.
|| Let’s delete the mirrored objects.

To choose more than one object, hold down the '''control''' key while

selecting.

Choose a '''mirrored''' object in the '''combo view''' and press the '''delete''' key.
|-
|| In the Draft modification tools select the Downgrade tool( shown as Down arrow).

Cursor on '''Downgrade''' tool tip.
|| The '''Downgrade''' tool converts complex objects into multiple simpler objects.
|-
|| Select the '''polygon''' and then the '''view''' tab in '''combo view'''.

Cursor on '''flat lines'''.
|| Select the '''polygon'''.

The object is shaded now.
|-
|| Click on the '''Downgrade''' tool.
|| Click once on the '''Downgrade''' tool.
|-
|| Video editing highlight on polygon changing to wire in comboview.
|| Notice the object is converted to '''wire''' and not shaded.
|-
|| Click on the '''Downgrade''' tool.
|| Click again on the '''Downgrade''' tool.
|-
|| Highlight wire changing to many objects in video.
|| Now the object is converted to multiple individual '''edge''' objects.
|-
|| Select one edge, move it or change line width or color.
|| Now the individuals can be edited separately.

This is a very useful feature while drawing.
|-
|| Press '''Ctrl+Z'''.
|| I will press '''control Z''' to undo the property changes of the edited object.
|-
|| Curson on the '''upgrade''' tool tip.
|| Next, let’s learn about the '''upgrade''' tool.
|-
|| Press '''Ctrl+A'''.
|| Press the '''control''' and '''A''' keys together to select all the edges.

You may also select them individually if needed.
|-
|| In the Draft modification tools select the Upgrade tool( shown as Up arrow).

Click on the '''upgrade''' tool once.
|| Click on the '''upgrade''' tool once.
|-
|| Point to the wire object.
|| The objects are now grouped together as a single wire object.
|-
|| Click on the '''upgrade''' tool again.
|| Click on the '''upgrade''' tool again.
|-
|| Highlight in video editing combo view - the '''wire''' is converted a '''face''' object.
|| Now the '''wire''' is converted to a face object.
|-
|| Downgrade twice the '''face''' object.
|| Pause this video and downgrade the '''face '''object again to single edges.
|-
|| Select only 4 of the edges and click on upgrade once.
|| Now select only 4 of the edges and upgrade them to a wire.
|-
|| Move the wire object.

Select the wire object and click on upgrade once.
|| Move the wire object slightly away.

Then, upgrade the wire object to a '''face'''.
|-
|| Cursor on the screen.
|| Notice the completed pentagonal face and also the edge that was not upgraded.
|-
|| In the '''Draft modification tools''' select the '''Trimex '''tool( shown as a line with two arrows).

Cursor on the '''Trimex''' tool.

Click on '''downgrade tool''' twice.
|| Let’s learn about the '''Trimex '''tool by downgrading the object back to 5 edges.
|-
|| Select one of the edges.
|| Click on one of the edges to select it as seen.
|-
|| Change '''line width''' to 5 for the selected line.
|| For clarity in the video, I will increase the '''line width''' to 5.

Adjust the zoom as desired.
|-
|| Click on the '''Trimex''' tool.
|| Now, click on the '''Trimex''' tool.

We will learn to extend and trim the line now.
|-
|| Drag the cursor away from the selected line.

click on a point on the canvas.
|| Move the cursor away from the end of the selected line.

To extend the line click on the desired spot on the canvas.
|-
|| Press '''Ctrl+Z'''.
|| I will undo this operation and demonstrate trim.

|-
|| Select the line. Click on '''Trimex'''.

Move the cursor to trim the line.
|| Again select the line and choose the '''Trimex tool'''.

Trim is dependent on the position and length of the trim.

Now we move the cursor a little to trim the line as seen here.

The region to be trimmed does not have the black overlay.
|-
|| Add an arrow on video editing.
|| Notice part of the line has a black overlay on the green selection.
|-
||
|| Left click once and notice the trimmed region.
|-
||
|| I will undo the trim by pressing '''control''' and '''Z''' keys together.
|-
|| Select the line, choose '''trimex''' and trim.
|| Let’s repeat the process.

Select the line, choose '''trimex''' and trim.
|-
|| Highlight the inversion of black highlighted region which will get trimmed.
|| Now carefully go past the half length of the line.

You will notice the black overlay region inverts after you pass the half mark.
|-
|| Click on the canvas.
|| Click on the canvas.

This time the shorter segment is deleted and not the starting segment.
|-
|| Press '''Control''' + '''A''', then press '''Delete'''.

Redraw the pentagon.

Change to wireframe style.
|| I will select all objects by pressing '''control''' and '''A''' keys together.

I will delete them and redraw a pentagon to learn the '''offset tool'''.

Use Wireframe style for clarity.
|-
|| Select the '''pentagon''' and then the '''offset tool'''.

In the '''Draft modification tools''' select the '''Offset '''tool( shown as two concentric open pentagons).

|| Select the '''pentagon''' and then the '''offset tool'''.
|-
|| point to the concentric object on the canvas.
|| Notice a concentric object as the cursor is moved on the canvas.

The concentric object can have a larger size or smaller size.
|-
|| point to the distance.
|| The distance from the parent is seen in the '''task tab'''.

Without moving the cursor, type 5 and press the E'''nter''' key.
|-
|| Show the enlarged object.
|| The object is now enlarged.
|-
|| Select the object and select '''offset''' again.
|| Pause the video, select the object and select the '''offset''' tool again.
|-
|| Check the '''Copy''' box in the '''task''' tab.

|| Now, check the '''Copy''' box in the '''task''' tab.
|-
|| '''Offset''' the object and show 2 concentric objects.
|| Again repeat the '''offset''' to create a smaller or larger dimension.

Left click on the '''canvas''' and notice that two objects are present now.
|-
||
|| Repeat this procedure with checking the box for OCC-style object.

Notice the extra edge around the vertices that is added now.
|-
|| Select the '''polygon'''.

Click on the '''rotate tool'''.(circular arrow tool)

|| Next, let’s rotate the object using the '''rotate tool'''.

Select the polygon and then click on the '''rotate tool'''.
|-
|| Cursor on '''Combo view panel''' parameters.

|| To rotate in a 2D plane, we have to set two parameters.

They are the axis of rotation and the angle of rotation.
|-
|| Highlight combo view in video.
|| First, let’s pick the pivot point for rotation.

Move the cursor in the canvas and notice only Δx and Δy changes.
|-
|| Left click at the desired position in the canvas.
|| Left click at the desired position in the canvas.
|-
|| Move the cursor and left click again.
|| Now the user is prompted to enter the base angle.

I will move the cursor and left click once again.

User can also type in the exact desired base angle without moving the cursor.
|-
|| For '''Rotation angle''' enter 90 and press '''Enter'''.
|| Now the axis of rotation is set.

User is now prompted to enter the rotation angle.

I will enter 90 without moving the cursor and press the''' Enter''' key.
|-
||
|| Notice the rotated object.

Users can practice the various options.
|-
||
|| As needed save your work and exit '''FreeCAD'''.
