Welcome to the next SelfCAD tutorial. In this instructable I'm going to show you how you can use profiles to model a simple barn. All you need is your SelfCAD account.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Create New SelfCAD Project
Launch SelfCAD Editor and create a new project. The only thing I changed there was the project's name.
Step 2: Draw Profile
Choose 3D Sketch tool. Turn on Left/Right plane, use Rotate X slider to rotate it 7 degrees and set the Offset to -200. Look at picture 2 to see how it should look like.
Open Precision Settings and turn on snapping to the grid vertices. Draw a profile like in the 4th picture.
Step 3: Draw Second Profile
Move the R/L plane to X 200 and rotate it in the opposite direction. Draw identical profile.
Step 4: Use Loft to Make a Mesh
With both profiles selected (they can be drawn as one object or separately) use Loft tool (C+L). Make sure you have checked filling first and last profile and set the smoothness to 4.
Step 5: Draw One More Profile...
Use 3D Sketch again to draw roof shape. Turn on Front/Back plane, rotate it and set its offset. Uncheck snapping to grid vertices and select minimum step size 10. Draw a new profile.
Step 6: ... and Again
Do the same with the second side.
Step 7: Create Roof
Use Loft again. This time filling options should be unchecked. Delete bottom face.
Step 8: Add Thickness to the Roof
Add thickness (M+A) to the roof.
Step 9: Model a Ridge
In edge selection mode move top middle edge at the same height as the roof. Choose Wireframe view mode and right view, then scale the edge in the Z dimension.
Step 10: Move and Scale Next Two Edges
Select the other two edges and do the same as before
Step 11: Add Cylinder to the Scene
Now it's time to create a door. Add a cylinder to the scene and set its radius and height. It should intersect with the wall
Step 12: Scale and Flatten the Cylinder
Scale the cylinder increasing its Y dimension, then find Flatten (D+L) tool in the Deform list and use it to flatten the bottom of the cylinder. Move the object to the grid (Y = 0).
Step 13: Add Thickness to the Walls
Delete the bottom face of the barn. Select the barn and add some thickness.
Step 14: Copy Cylinder
Select the cylinder. In Tools find Copy Offsets (C+O) and don't change anything, just add copy the cylinder one time.
Step 15: Subtract Cylinder From the Wall
Select one of the cylinders and the barn. Use Stitch & Scoop, Difference (B+D) to subtract cylinder from the barn.
2nd picture shows how the result should look like. Notice that the second cylinder is invisible, but exists.
Step 16: Model a Door
Use the second cylinder to model the door. Make it thinner and rotate as in picture 2.
Step 17: Complete the Door
If you want, you can open the door :)
Step 18: Cut a Hole for Window
Add a smaller cylinder and move it above the door. Use Stitch & Scoop to cut a hole for a window.
Step 19: Use Magic Blocks
Select the barn (walls) and use Magic Blocks (C+B). Set the block density value so make the barn look like made of planks.
The barn is ready!
