Using BIM Quickdraw

Command: BimQuickDraw

Overview: In this lesson, you will learn how to use the QuickDraw tool to easily create and edit, rectangular and L-shaped rooms and buildings.

Lesson Objectives

After completing this lesson, you will be able to:

• Use the magnetic snapping feature.
• Define the room height, wall width, and slab thickness.
• Align the rooms with existing walls.
• Make a story
• Make a flat roof

About

The Quickdraw tool allows you to get started with conceptual modeling easily. It also automatically adds BIM data. You can use the Quickdraw tool to create a room or a whole building. Once in use, Quickdraw will remain active until you explicitly exit the command or until another command is executed.

For more information about this command, visit the Command Reference article BimQuickDraw.

The magnetic snapping feature

With the magnetic snapping feature, you can easily align the QuickDraw cursor. When the command is active, move the cursor close to the object you want to align to. The QuickDraw cursor automatically snaps to the object.
You have the following options:

1. Align to the origin
2. Align to existing walls	To the wall itself
	To the extents of the wall
3. Align to lines	To grid lines Note: If you use Quickdraw to copy a story, the gridlines will only be copied if the grid is assigned to the same spatial location of the ground floor slab and walls. If this is not the case, the gridlines that lie in the boundary of the ground slab will be projected on the slab of the top floor. This is only a visual help. The gridlines on the slab of the top floor will disappear when you exit the Quickdraw command.
	To X- and Y- aligned lines and line segments
	To parallel lines

Setting the Quickdraw system variables

You can use the Quickdraw Settings to set the Quickdraw system variables:

1. When the Quad cursor is in the 'No Selection' state (nothing is highlighted or selected), select Quickdraw from the Model tab, click the Quickdraw icon in the ribbon or type BIMQuickdraw in the commandline.

2. You are prompted: Select first point or [quickdraw Settings]:

3. Enter S for the Quickdraw Settings.

4. Specify a new value to the system variables of Quickdraw to change their default values (e.g. Default Wall Width, Default Slab Thickness, and Default floor to floor distance).
   When the "auto adapt sizes"-option is turned on, the dimensions of the walls and slab of the new room will be the same as the walls and slab you snap to.

   

Changing system variables while running Quickdraw

It is possible to edit the dimensions of the walls you will draw while the Quickdraw command is launched. Change these settings in the Quickdraw Settings dialog box, select the settings in the prompts menu or enter the specific letters in the commandline and press Enter to change the dimensions.

• H: Change the dimension of the floor height.
• W: Change the dimension of the wall width.
• T: Change the dimension of the slab thickness.
• A: Adapt the dimensions of the room you are drawing in/against automatically.

Note: Make sure that you enable the hidden options in the prompt menu. Type PromptMenuFlags in the commandline, press Enter and enter option 1.

Procedure: Creating an L - shaped house

1. When the Quad cursor is in the 'No Selection' state (nothing is highlighted or selected), select Quickdraw from the Model tab, click the Quickdraw icon in the ribbon or type BimQuickdraw in the commandline.

   You are prompted: Select the first point or [quickdraw Settings]:

   Note: Use the Quickdraw Settings to change the wall width, wall height and slab thickness of the room before you click and then specify the first corner of a building.

2. Select any point in the drawing area to set the first corner.

   Note: To start from the origin, use the magnetic snapping feature of Quickdraw.

4. Drag the mouse cursor to define the footprint of the building.

   Note: If the Dynamic dimension (DYN) option is on, the current values of the room width (1) and length (2) are displayed in a dynamic dimension field.

   

   Specify the values of the room width and length in the Dynamic dimension field. Press the Tab key to switch between width and length and press Enter or just click freely. Press Enter or Escape to leave the Quickdraw command or you can continue to create more rooms.

5. Place the Quickdraw cursor inside the existing building to create more rooms.

   When you place the Quickdraw cursor inside the existing building, the dynamic dimension fields display the distances from the Quickdraw cursor to the adjacent walls (3,4,5,6).
   When the "auto adapt sizes"-option is turned on, the dimensions of the walls of the new room will be the same as the wall you snap to.
   

   If the cursor aligns with one or two existing walls in the model, the layout of the cursor will adapt and depict the alignment.

   

   To actually draw new walls, choose the distances from the already existing walls to specify your first point. Move your cursor or type the values in the dynamic dimension fields to do this. Draw walls in the same way as explained in steps 2 and 3.

6. To remove a section of a wall from the existing room, first, align the Quickdraw cursor with an existing wall at the inner side of the building. Then click and drag the cursor outside of the existing building.
   The outer wall will turn red (9) to indicate the part of the wall that will be removed.

   Note: you can also align your cursor with an existing wall at the outer side of the building to remove a part of the slab. Then click and drag the cursor inside the existing building.

7. Select a second point. The wall highlighted in red will automatically be deleted and an L shaped room will be created.

   

Procedure: Creating a story and a roof

Start with a similar configuration:

Go through the following steps to create two extra stories, a floating part and a flat roof.

1. When the Quad cursor is in the 'No Selection' state (nothing is highlighted or selected), select Quickdraw in the Model tab or type BIMQuickdraw in the commandline.

2. Click on the icon () to see the options:

   • Fully copy the top floor. All features will be copied (windows, doors, interior walls, and furniture, excluding doors on the outer walls of the ground floor).
   • Copy the slab and the outer walls of the top floor.
   • Finish the building with a flat roof.

3. For the first story, choose the first option ( Full copy).
   
   Note: The interior wall and interior door and the windows in the exterior wall are copied. The door in the exterior wall on the ground floor is not copied.
   Note: The furniture is not copied in this case, because it is not assigned to the ground floor (see the Properties panel). If you want to copy the furniture, use Bimify to assign the furniture to a spatial location. The new furniture will be automatically assigned to the new spatial location.
   Note: Walls inherit the spatial location of the slab on which they are created.

4. Repeat step 2. Choose the second option (Copy the slab and the outer walls) to create the top story.
   

5. To make the overhang you should remove parts of the outer walls of the second floor. First, snap the Quickdraw cursor in the corner of the two outer walls, inside the building. Then click and drag the cursor outside.
   The outer walls will turn red to indicate that the walls will be removed.
   

6. Use the same method as in step 2, selecting option 3 (Finish the building with a flat roof).
   

Procedure: Using Quickdraw starting from a 2D layout

1. Open a 2D floorplan of a rectangular or L-shaped building.

   

   Note: it is also possible to draw a simple 2D floor plan with the (poly)line command to start from. In this case, the default wall thickness of the BIM Quickdraw command will be used.
   Note: The Quickdraw cursor now supports snapping to (double) lines inside XREFs.

2. When the Quad cursor is in the 'No Selection' state (nothing is highlighted or selected), select Quickdraw in the Model tab, click the Quickdraw icon in the ribbon or type BIMQuickdraw in the commandline.

3. Hover over one of the outer walls with the cursor.

   

   Note: The thickness of the wall automatically adapts to the distance between the parallel lines of the 2D drawing.

   Note: If the lines in the (imported) 2D floorplan are not optimal (e.g. not exactly X- or Y-aligned), the QuickDraw-cursor will not snap to it (as it is perfectly X-Y-aligned). In that case, use the Optimize command to make sure all 2D lines exactly X- or Y-aligned.
   
   

4. Draw the outer walls, using the magnetic snapping feature to snap to the lines of the 2D drawing.

   

5. Hover over one of the inner walls with the cursor, using the magnetic snapping feature to snap to the lines of the 2D drawing.

   
   Note: The thickness of the wall automatically adapts to the distance between the parallel lines of the 2D drawing.

6. The 2D plan has been transformed into a 3D model.

   

   Note: you can use the same method as in step 2 and 6 of the previous procedure to add floors or finish the building with a flat roof.
