Step 1: Press the R key on your keyboard to enter the RECTANGLE command.

Select the plane that you would like to start sketching on. In this instance we will use the XY plane (the floor).

Step 2: Draw a 2-point rectangle.

Ideally you should place the first corner on the grid as shown. At this stage dimensions are not important.

Step 3: Press the D key on your keyboard to enter the DIMENSION command.

Click on the shorter side of the rectangle and enter a dimension of 50mm.

Repeat this process with the longer line and enter a dimension of 150mm.

Step 4: Click on the green tick in the top right corner of the screen to 'finish sketch'.

This will change your view to isometric.

Step 5: Press the E key on your keyboard to enter the EXTRUDE command.

Select the rectangle you created in step 3 and pull this outwards.

Size should be 50 mm exactly.

Step 6: Press the A key on your keyboard to enter the APPEARANCE command.

Select the bamboo material from the list and drag this directly onto the model.

Step 7: Press the L key on your keyboard to enter the LINE command.

Select the top face of your cuboid to start a new sketch here (this will change your view to view the cuboid from above).

Step 8: With the LINE command still selected, draw guidelines on the top of the cuboid.

Carefully look at the grid spacings and carefully draw a vertical line.

Line 1: Draw line 1 after 1 grid space (or 10mm).

Line 2: Draw line 2 after 4 grid spaces (or 40mm).

Line 3: Draw line 3 after 5 grid spaces (or 50mm).

Line 4: Draw line 4 after 8 grid spaces (or 80mm).

Line 5: Draw line 5 after 11 grid spaces (or 110mm).

Line 6: Draw line 6 after 14 grid spaces (or 140mm).

Step 9: With the LINE command still selected, draw additional guidelines on the top of the cuboid.

Carefully create diagonal lines to help identify center points.

Step 10: Press the C key on your keyboard to create a CIRCLE from a center point.

Select the center point where the first diagonal line and midline cross over and drag a circle outwards.

First circle: The first circle size should be exactly 30 mm. Press Enter to complete this circle.

Again, press the C key on your keyboard to create a CIRCLE from a center point.

Select the second center point where the second diagonal line and midline cross over and drag a circle outwards.

Second circle: The second circle size should be exactly 9mm. Press Enter.

Repeat this process for circles 3 and 4 (both should be 9mm).

Step 11: Click on the green arrow in the top right corner of the screen to 'finish sketch'.

Step 12: Press the E key on your keyboard to enter the EXTRUDE command.

Select all the circles you created in step 10 and pull these downwards by 30mm.

Step 13: Press the R key on your keyboard to enter the RECTANGLE command.

Select the front face of your cuboid to start a new sketch here (this will change your view)

Select the first point of the rectangle at the bottom-left of your cuboid. Create a rectangle that measures 15 grid spaces wide by 6 grid spaces high.

Step 14: Click on the green arrow in the top right corner of the screen to 'finish sketch'.

This will change your view to isometric.

Step 15: Press the E key on your keyboard to enter the EXTRUDE command.

Select the rectangle you created in step 13 and pull this outwards.

Size should be 3mm exactly.

Step 16: Press the R key on your keyboard to enter the RECTANGLE command.

Select the front face of your cuboid to start a new sketch here (this will change your view)

Select the first point of the rectangle at the bottom-left of your cuboid. Create a rectangle that measures 15 grid spaces wide by 2 grid spaces high.

Step 17: Click on the green arrow in the top right corner of the screen to 'finish sketch'.

This will change your view to isometric.

Step 18: Press the E key on your keyboard to enter the EXTRUDE command.

Select the rectangle you created in step 16 and pull this outwards.

Size should be 20mm exactly.

Step 19: Press the L key on your keyboard to enter the LINE command.

Select the front face of your new cuboid to start a new sketch here.

Select the first point of the line at the bottom-left of your cuboid.

1. Draw a horizontal line measuring 120mm long.

2. From the same start point, draw a vertical line measuring 90mm high.

3. Draw a third line connecting the two previous lines.

Step 20: Click on the green arrow in the top right corner of the screen to 'finish sketch'.

This will change your view to isometric.

Step 21: Press the E key on your keyboard to enter the EXTRUDE command.

Select the triangle you created in step 19 and pull this outwards.

Size should be 3mm exactly.

Step 22: Select the ORBIT tool from the navigation menu at the bottom of the page.

Left-click and hold the button down anywhere on the screen. Move your cursor or trackpad to spin the model around.

Alternatively, select the back of the model using the view cube.

Step 23: Press the L key on your keyboard to enter the LINE command.

Select the back face of your cuboid to start a new sketch here.

Start a new line from the bottom-right corner. Create a new vertical line measuring 150mm. Press Escape to exit the tool.

Press L to enter the LINE command again (to start a new line).

From the same start point, create a horizontal line measuring 150mm.

Step 24: Select the 'Create' drop-down menu.

Go to 'Arc' > '3-Point Arc'.

1. Select the top end of line 1.

2. Select the left end of line 2.

3. Create an arc.

Press OK.
