|| Welcome to the tutorial on '''Draft Modification Tools'''.
|-
|| 0:07
| In this tutorial,
|-
|| 0:09
| We will perform the following object operations
|-
|| 0:12
| Mirror, '''Offset '''
|-
|| 0:15
|| Delete
|-
|| 0:17
|| Trim, Extend
|-
|| 0:19
|| Downgrade, Upgrade
|-
|| 0:22
|| Rotate and Line segmentation
|-
|| 0:26
|| To record this tutorial, I am using
|-
|| 0:29
|| '''Windows 11 '''OS
|-
|| 0:32
|| and '''FreeCAD 0.21.1'''
|-
|| 0:37
|| To follow this tutorial,
|-
|| 0:39
|| Learners must be familiar with the '''FreeCAD''' interface.
|-
|| 0:44
|| For '''pre-requisit'''e tutorials, please visit this site.
|-
|| 0:49
|| The files used in this tutorial are provided in the '''code files''' link.
|-
|| 0:54
|| Please download and extract the files
|-
|| 0:58
|| Make a copy and use them while practising.
|-
|| 01:02
|| I have opened '''FreeCAD''' and opened the file provided with this tutorial.
|-
|| 01:09
|| First let’s mirror the polygon using '''Draft Modification Tools'''.
|-
|| 01:15
|| Select the pentagon and click on the '''Mirror''' tool as seen.
|-
|| 01:20
|| Move the cursor to the canvas to draw the mirror angle and direction.
|-
|| 01:26
|| Left click to set the first point and move the cursor to see the mirror line.
|-
|| 01:34
|| In 2 dimensions this will be a line.
|-
|| 01:38
|| I will draw a vertical line on the canvas to set the mirror line.
|-
|| 01:43
|| When a tool is chosen, report view will prompt the user for the next action.
|-
|| 01:50
|| Select the second point and left click again.
|-
|| 01:55
|| Notice the '''pentagon '''is mirrored.
|-
|| 01:57
|| The mirrored object and the parent are equidistant from the mirror.
|-
|| 02:04
|| Pause the video and draw a mirror through the object.
|-
|| 02:08
|| Notice the parent and child overlap
|-
|| 02:13
|| Since they are symmetrically placed.
|-
|| 02:16
|| Let’s delete the mirrored objects.
|-
|| 02:20
|| To choose more than one object, hold down the '''control''' key while

selecting.
|-
|| 02:27
|| Choose a mirrored object in the '''combo view''' and press the '''Delete''' key.
|-
|| 02:33
|| The '''Downgrade''' tool converts complex objects into multiple simpler objects.
|-
|| 02:40
|| Select the polygon.
|-
|| 02:42
|| The object is shaded now.
|-
|| 02:45
|| Click once on the '''Downgrade''' tool.
|-
|| 02:49
|| Notice the object is converted to '''wire''' and not shaded.
|-
|| 02:55
|| Click again on the '''Downgrade''' tool.
|-
|| 02:59
|| Now the object is converted to multiple individual '''edge''' objects.
|-
|| 03:05
|| Now the individuals can be edited separately.
|-
|| 03:10
|| This is a very useful feature while drawing.
|-
|| 03:13
|| I will press '''control Z''' to undo the property changes of the edited object.
|-
|| 03:20
|| Next, let’s learn about the '''upgrade''' tool.
|-
|| 03:24
|| Press the '''control''' and '''A''' keys together to select all the edges.
|-
|| 03:29
|| You may also select them individually if needed.
|-
|| 03:33
|| Click on the '''upgrade''' tool once.
|-
|| 03:36
|| The objects are now grouped together as a single wire object.
|-
|| 03:41
|| Click on the '''upgrade''' tool again.
|-
|| 03:45
|| Now the '''wire''' is converted to a face object.
|-
|| 03:49
|| Pause this video and downgrade the '''face '''object again to single edges.
|-
|| 03:56
|| Now select only 4 of the edges and upgrade them to a wire.
|-
|| 04:02
||Move the wire object slightly away.
|-
|| 04:07
|| Then, upgrade the wire object to a '''face'''.
|-
|| 04:12
|| Notice the completed pentagonal face and also the edge that was not upgraded.
|-
|| 04:19
|| Let’s learn about the '''Trimex '''tool by downgrading the object back to 5 edges.
|-
|| 04:27
|| Click on one of the edges to select it as seen.
|-
|| 04:32
|| For clarity in the video, I will increase the '''line width''' to 5.
|-
|| 04:38
|| Adjust the zoom as desired.
|-
|| 04:41
|| Now, click on the '''Trimex''' tool.
|-
|| 04:45
|| We will learn to extend and trim the line now.
|-
|| 04:49
|| Move the cursor away from the end of the selected line.
|-
|| 04:55
|| To extend the line click on the desired spot on the canvas.
|-
|| 05:01
|| I will undo this operation and demonstrate trim.
|-
|| 05:05
|| Again select the line and choose the '''Trimex tool'''.
|-
|| 05:09
|| Trim is dependent on the position and length of the trim.
|-
|| 05:15
|| Now we move the cursor a little to trim the line as seen here.
|-
|| 05:21
|| The region to be trimmed does not have the black overlay.
|-
|| 05:25
|| Notice part of the line has a black overlay on the green selection.
|-
|| 05:33
|| Left click once and notice the trimmed region.
|-
|| 05:37
|| I will undo the trim by pressing '''control''' and '''Z''' keys together.
|-
|| 05:43
|| Let’s repeat the process.
|-
|| 05:46
|| Select the line, choose '''trimex''' and trim.
|-
|| 05:50
|| Now carefully go past the half length of the line.
|-
|| 05:56
|| You will notice the black overlay region inverts after you pass the half mark.
|-
|| 06:02
|| Click on the canvas.
|-
|| 06:05
|| This time the shorter segment is deleted and not the starting segment.
|-
|| 06:12
|| I will select all objects by pressing '''control''' and '''A''' keys together.
|-
|| 06:18
|| I will delete them and redraw a pentagon to learn the '''offset tool'''.
|-
|| 06:24
|| Use '''Wireframe''' style for clarity.
|-
|| 06:28
|| Select the '''pentagon''' and then the '''offset tool'''.
|-
|| 06:32
|| Notice a concentric object as the cursor is moved on the canvas.
|-
|| 06:39
|| The concentric object can have a larger size or smaller size.
|-
|| 06:45
|| The distance from the parent is seen in the '''task tab'''.
|-
|| 06:50
|| Without moving the cursor, type 5 and press the '''Enter''' key.
|-
|| 06:56
|| The object is now enlarged.
|-
|| 07:00
|| Pause the video, select the object and select the '''offset''' tool again.
|-
|| 07:06
|| Now, check the '''Copy''' box in the '''task''' tab.
|-
|| 07:10
|| Again repeat the '''offset''' to create a smaller or larger dimension.
|-
|| 07:17
|| Left click on the '''canvas''' and notice that two objects are present now.
|-
|| 07:23
|| Repeat this procedure with checking the box for '''OCC'''-style object.
|-
|| 07:32
|| Notice the extra edge around the vertices that is added now.
|-
|| 07:37
|| Next, let’s rotate the object using the '''rotate tool'''.
|-
|| 07:44
|| Select the polygon and then click on the '''rotate tool'''.
|-
|| 07:49
|| To rotate in a 2D plane, we have to set two parameters.
|-
|| 07:55
|| They are the axis of rotation and the angle of rotation.
|-
|| 08:00
|| First, let’s pick the pivot point for rotation.
|-
|| 08:05
|| Move the cursor in the canvas and notice only '''Δx''' and '''Δy''' changes.
|-
|| 08:13
|| Left click at the desired position in the canvas.
|-
|| 08:17
|| Now the user is prompted to enter the base angle.
|-
|| 08:23
|| I will move the cursor and left click once again.
|-
|| 08:27
|| User can also type in the exact desired base angle without moving the cursor.
|-
|| 08:34
|| Now the axis of rotation is set.
|-
|| 08:39
|| User is now prompted to enter the rotation angle.
|-
|| 08:44
|| I will enter 90 without moving the cursor and press the '''Enter''' key.
|-
|| 08:50
|| Notice the rotated object.
|-
|| 08:54
|| Users can practice the various options.
|-
|| 08:57
|| As needed save your work and exit '''FreeCAD'''.
|-
|| 09:01
|| Now let's summarize.
|-
|| 09:04
|| In this tutorial, we learned about various '''Draft modification tools'''.
|-
|| 09:10
|| They are:
|-
|| 09:11
|| '''Mirror''', '''Upgrade''' and '''downgrade'''
|-
|| 09:14
|| Rotate
|-
|| 09:16
|| '''Trimex '''and
|-
|| 09:18
|| '''Offset'''
|-
|| 09:19
|| For assignment activity, please do the following.
|-
|| 09:23
|| Draw a line
|-
|| 09:24
|| Scroll down to '''subdivisions''' in the '''value''' tab in '''combo view'''
|-
|| 09:30
|| Change it to 5 and press '''Enter'''
|-
|| 09:34
|| Move the cursor over the line
|-
|| 09:37
|| Notice the 6 equal segments
|-
|| 09:41
|| Practice the '''modification''' tools learned in this tutorial.
|-
|| 09:46
|| Rotate, offset, downgrade, upgrade and mirror tools.
|-
|| 09:51
