## Introduction: Barn Modeling | SelfCAD

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.

## 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.
