This tutorial describes how to make a page holder. You can slide it over your thumb, and it holds the pages while reading:

More importantly, in this lesson you will learn: 

  • The basics of sketching
  • How to pull 2D sketches into 3D objects with "Extrude"
  • How to create holes (and subtract objects from each other)
  • Finishing touches: The basics of fillets/chamfers 

Getting Started:

First, make sure you are signed up and logged in. If you previously created an account, you can log in by pressing "Browse Designs" or navigating to https://3DOrchard.com/app and pressing the menu button in the top-right:

Then press "Login:"

Once logged in, press the button in the bottom-left to start a new design:

Once the 3D modeling interface loads, you should see the interface. 

You may also see the tutorial. You can go through the tutorial and return to this one, or just close it and complete it later:

For navigation: Left-click and drag to rotate the camera, and right-click and drag to pan the camera, and scroll to zoom in and out. 

If you get lost, you can re-orient the camera using the camera controls in the bottom right. Just single click the camera and click "Fit View:" 

Step 1: Starting a Sketch 

Hover your mouse over the center, and single left-click the bottom, blue plane:

Then click "Sketch" 

This is sketch mode, where you will create 2D sketches that you will pull into 3D objects. By default, the grids represent 1 square centimeter (cm). These settings can be changed in the menu in the top-right.

Along the bottom, you'll notice the sketching toolbar: 

The checkmark on the left accepts and closes the sketch. Next to that is the cursor for the "Select" tool, which is used to select and modify the sketches:

Next to that are the tools to sketch lines, circles, and arcs: 

Step 2: Sketching

 Select the "Circle" Tool: 

Draw a circle in the center of the sketch plane by single-clicking the center point, then click a second time to place the circle 1 square away from the center: 

Now select the draw line tool: 

Now single-click to place the first point of the line 3 squares (3cm) to the left of the center, and the second point 2cm above the center:

The line will continue to follow your mouse until a closed-loop is created (i.e. the first point connects with the last point). You'll notice that the line is a dark blue, indicating it's not a closed loop. Continue drawing a diamond around the circle:

Step 3: Constraints

Sometimes the initial sketch doesn't turn out like we wanted, so we can modify it and "Constrain" the different sketch elements with the "Select" tool. Enter Select mode by pressing the mouse cursor or pressing "Esc" twice. 

Select the top, point and hold ctrl (or command) and select the center point:

You'll notice a raw distance, vertical distance, and horizontal distance. Enter 2 for the vertical distance, and press the checkmark to constrain the distance:

Now that point will always stay 2cm above that point. To hold it vertically above that point, click the "Vertical" constraint:

You can do things like constrain the lengths of lines, radius of circles and arcs, as well as setting lines parallel or perpendicular to each other, set angles between lines, etc. 

Once the sketch is constrained and dimensioned like the one below, move on to Step 4:

Note: If your sketch won't close because it says to "close open loops," it is because you likely sketched too many lines, or lines with points that connected with themselves. You can try to drag the points in select mode to find which lines are not connected. Alternatively, your best bet may be to just force close the sketch with the red "X," and try to draw the circle and diamond again (via steps 2 & 3). 

Step 4: Turn 2D Sketch into 3D Objects

Press the green checkmark to close the sketch: 

The sketch tools should have disappeared and you should see your new sketch:

Select both the diamond and the circle. Single-click the diamond outline. Then, holding Ctrl (or Command), single-click the inner circle:

Press "Extrude:"

Keep the magnitude the default of "1 cm," and press the checkmark to accept: 

You have now pulled the 2D sketch into a 3D object! 

Step 5: Cutting the hole

We now want to subtract that cylinder from the diamond with the "Cut" tool. On Orchard, you can combine different shapes in different ways; you can fuse them together, cut one from another, or take the intersection between two shapes:

In this case, we want to cut the cylinder from the diamond shape. So first, we select the shape to be cut and then we select the "Tool" we want to cut it with.

Double-click the diamond shape to select it. Then, holding ctrl (or command), double-click the cylinder to select it too:

Select "Cut:" 

"Keep Tool" is available if you wanted to keep the cylinder to use in later cuts. In this case, we want to get rid of the cylinder, so we have "Keep Tool" toggled off. When you press the checkmark, you should now have a hole: 

Note: If you're getting an error that says "Could not cut parts," you're likely selecting the cylinder first before the diamond. Try selecting the diamond THEN the cylinder.

Step 6: Finishing Touches
Normally, it's recommended that you publish your design before putting in the finishing touches so if you want to make changes, you can always come back to this earlier version. But for now, we need to round off those sharp edges.

Select the inside cylinder, press "Fillet," and enter 0.25 cm: 

Now, select each outer edge and do the same 0.25cm fillets (remember, you can select multiple edges at the same time): 

Finally, select the top and bottom faces, and select "Chamfer" to flatten the edges:

Optional: Adding materials

You can add materials to the part by double-clicking it to select it, then pressing the materials button in the bottom-right: 

When finished setting material, color, texture etc, press "Save Material" to apply it. 

Step 7: Publish your design

Voila! You can now save your design. Press "Publish" in the top-right to create a new "Seed" design on Orchard:

 Here you can give your design a name a description, and give it a category. In the "Parts" tab, you will see all of the parts in the scene. Make sure to name the parts: 

Set the category: 

Then press "Save."
Note: Wait until the "Success" message before navigating back. 

Step 8: What to do next

Now that your design is saved, you can view it by going to your profile in the top-left: 

Or by filtering the designs by creation time in the top-right (assuming you just created it): 

You can share it with friends:
