3D House Foundation Basic Tutorial

• Creating a 3D foundation is easy:
  • Open a new 2D drawing.
    • In OPTIONS set 2D workplane to X-Z.
  • Draw the following layout in 2D.
    • Hint: Use a grid with .5 Minor 10 Major.  Show me.
    •  Measurements are from from the CENTERLINE of the foundation so the extrusion of the foundation profile maintains correct position.
  • Combine all outside lines ('B'). [All lines must be VECTORS not planes.]
  • IMPORTANT: Draw inside walls in the direction of ARROWS to assure correct orientation of extrusions
  • Draw the foundation profile (shown in RED)

•  Foundation profile detail.

• Switch to 3D mode and ZOOM in on the profile
  • Make sure 'Enable Sticky Handles' is on in OPTIONS->General.
  • Select profile and then use CTRL+H to set a handle as shown using MIDPOINT SNAP. (at 0)

• Now ROTATE it ('R')
  • Choose  X axis
  • Enter 90 deg.
  • Hit ENTER

• With a sticky handle set you can select the profile anywhere and the handle will guide the extrusion.
• Hit 'X' and choose options shown.
  • 'X' is Hotkey for Extrude.
• Start with the inside walls.

  • The profile does not have to be touching the foundation lines, it will extrude from where it is..

  • If the wall was drawn in the correct direction the extrusion should orient properly.

• Finish with the outside walls.
  • Just hit F3 to repeat extrude command.
  • If outside wall lines are not properly joined, you will not get the mitered corners.

• A top sill can be placed in the same way.
  • Draw the profile in 2D mode. (X-Z plane)
    • Turn off snap grid for distances less than .5 ft
  • 
  • Set a handle on the middle of the bottom.
  • Rotate 90 deg on X axis to X-Y plane.
  • Extrude along the same lines.
