2D, 3D, BIM - 8: The House P1 - Walls and Floors

2D, 3D, BIM - 8 The House P1 - Walls and Floors

In the first blog post in this series we looked how to extrude a simple house layout from a 2D plan. However, there is a better and faster way of doing this! In this post I'm going to show you how to use QuickDraw and a few other handy BIM tools to get this project moving. There are still many, many ways of using BricsCAD, but this will give you a good starting point.

This week you will need BricsCAD BIM. Don't worry, if you don't have BricsCAD BIM. You can still use QuickDraw with our free 3D modeling software: BricsCAD Shape

Floor 0

I began with QuickDraw. I then used the PolySolid tool, extruded a floor and assigned BIM properties to create the basic layout. The ground floor is going to be a shop, so I am leaving open plan. We will cover this area at a later date.

How to Do This
  1. Access BIMQUICKDRAW and draw the outline of your building. QuickDraw snaps to the origin (0,0,0).
    Note: Use TAB to switch between dimensions.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 1 quickdraw
    You can change the height, wall thickness, and slab thickness. For this example I am using wall Width: 0.1. slab Thickness: 0.25.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 2 menu
  2. Use POLYSOLID to draw an angular extension at the back of the building. Hit Ctrl to change the alignment of the polysolid. Here I am using "Right justify".
    Note: Set the polysolid thickness to match the walls.
    2D, 3D, BIM - 8 The House P1 - Walls and Floors- 2 polysolid
  3. Use Connect to Nearest to tidy up the junction.
    Note: If you can't remember how to do this, see Part 1.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 3 connect to nearest
  4. Now hover over the boundary and EXTRUDE up.
    Note: If you can't remember how to do this check part 2.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 4 boundar extrude
  5. BIMCLASSIFY the newly created walls: 'Wall'.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 5 bimclassify wall 2
  6. BIMCLASSIFY the newly created walls floor:'Slab'.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 7 bimclassify slab 2
  7. Select all the newly created BIM objects. In the Properties panel change the values: Building: Building. Story: Floor 0.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 6 properties

Floor 1

I duplicated the floors and edited with Quickdraw. I also added 2 balconies with Slice and Extrude.

How to Do This
  1. Use QUICKDRAW. Click the 2D, 3D, BIM - 8 The House P1 - Walls and Floors- blueplus plus sign in the corner of the building to duplicate the layout to the second floor. Select 'Fully copy the top floor'.
    Note: Because we have assigned the BIM data (spatial location) to the elements on Floor 0, these elements were also duplicated. QuickDraw copy doors, windows, columns and any other elements that have been assigned the correct data. Read more on BIM classification.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 8 fullycopy
  2. Now add a room to your building. QuickDraw automatically snaps to existing walls. Drag and click or manually type in the dimension of the room. You can choose to use internal or external measures as constraints.
    Note: Make sure that DYN (Dynamic Dimensions) is switched 'on' or you will not be able to manually type in the dimensions.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 9 addroom
  3. Draw another room.
    Note: QuickDraw automatically aligns to other drawing elements, keeping rooms inline and allowing you to model quickly.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 10 addanotherroom
  4. Continue with QuickDraw to complete the layout of the second floor.
    Note: QuickDraw correctly finishes the connections between the walls.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 11 addanotherroom
  5. Use Multi-Slice to cut the end panel. Height from ground: 1.3.
    Note: If you can't remember how to do this, see Part 3.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 12 multi slice
  6. EXTRUDE the face with the 'Subtract' Option. You've now created a balcony. Simple!2D, 3D, BIM - 8 The House P1 - Walls and Floors- 13 extrude
  7. Draw a rectangle between the walls of the small roof on the left of the house. Height from the ground: 1.3.
    Note: Hit Shift to assign the UCS to the wall face, the face will turn blue.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 14 polyline
  8. EXTRUDE the boundary to create another, smaller balcony.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 15 extrude

Floor 2

I duplicated the layout from Floor 1 and edited using QuickDraw, Extrude, and BIMDrag. I then added another balcony using the same techniques as Floor 1.

How to Do This
  1. Use QUICKDRAW. Click the 2D, 3D, BIM - 8 The House P1 - Walls and Floors- blueplus plus sign in the corner of the building to duplicate the layout to the second floor. Select the 'Fully copy the top floor' option.2D, 3D, BIM - 8 The House P1 - Walls and Floors- duplicate
  2. ERASE the balcony.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 17 erase
  3. Extrude the boundary above the lower balcony.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 18 extrude
  4. Repeat for the wall.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 19 extrude
  5. Use BIMQUICKDRAW to add a small room.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 20 quickdraw toilet
  6. ERASE the wall on the other side.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 21 erase
  7. Click the wall face and use BIMDRAG to move the wall. The adjoining walls will move at the same time.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 22 bimdrag
  8. Use BIMQUICKDRAW to finish the layout.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 23 quickdraw
  9. Repeat steps 8 and 9 from Floor 1 to complete the balcony.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 25 extrude

Outhouse

As a final touch, I added an angled outhouse using QuickDraw and custom UCS.

How to Do This
  1. Type UCS into the command line.
  2. Set the UCS to align with the face of the back balcony.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 26 ucs
  3. Draw a simple garage with BIMQUICKDRAW. QuickDraw is now aligned to the new UCS.
    2D, 3D, BIM - 8 The House P1 - Walls and Floors- 27 outhouse
  4. Add a flat roof using QuickDraw. Click the plus symbol and choose 'Finish the building with flat roof'.
    Note: The structure browser displays this as a different building, if you duplicate the layout, it only duplicates the details from this building.2D, 3D, BIM - 8 The House P1 - Walls and Floors- 28 flatroof

The final result should look something like this:
