In part 2 of the tutorial, you place foundation walls, exterior walls, and interior walls, and use the Trim/Extend tool to create an opening for a corridor.
This video demonstrates the following:
All elements have an associated level when they are placed in a project. If you are working in a plan view, the associated level is established from that view. For example, you want to add some walls and have them start from the foundation level, so you will open this view by double-clicking it in the Project Browser. To begin placing walls, you select the Wall tool.
Once the tool is selected, you can use the Type Selector at the top of the Properties palette to specify the type of wall you want to place, in this example, a retaining wall. The height of the wall is specified on the Options Bar. If a level datum already defined in the project is selected, then the top of the wall will be constrained to that level. Here, the entry level is selected for the top constraint of the wall.
The height of the wall can also be set to Unconnected, in which case, you enter an explicit value for the wall height. The wall location line is also set on the Options Bar. This setting establishes where the wall will be positioned in relation to the click points as the wall is placed. The interior finish face will be used for these walls.
The Chain option lets you draw connected walls, with each mouse click beginning a new segment. The points 1 through 4 are clicked in order to place the retaining walls. With the first retaining walls placed, the top constraint is changed on the Options Bar to be the lower level. A new series of walls is placed clicking points from A to F. Before clicking at point B, the Spacebar is used to flip the wall, positioning it so it will stay in line with the adjacent wall. A 3D view of the project can be created to see the walls that were placed in the plan view.
Note that the walls on the left side of the model are higher because the top constraint was set to the 02 Entry Level, while the other walls had a top constraint of the 01 Lower Level. The walls for the upper portion of the building are a different type, but they follow the same outline as the walls below. Rather than redraw all of these walls, the walls which were just drawn are selected using a window selection, and copied to the clipboard.
The walls can now be pasted to another level in the project. To do this, you use the Paste Aligned to Selected Levels tool, and select the entry level. With the pasted walls still selected, use the Type Selector to change them to a generic wall type. The wall type can still be changed later in the project, but for now, a generic wall close to the correct size of the finished wall can be used until the details are known.
The Properties palette can also be used to specify the roof level as the top constraint for these walls. The changes made in the Properties palette are applied to all of the currently selected objects. Pressing the Esc key will deselect everything. Now the walls along the right side of the model are selected.
Elements can be added to a selection by pressing and holding the Ctrl key while selecting with the mouse. For these walls, the base constraint will be changed to the 01 lower level so that they will extend down to meet the retaining wall below.
To create interior walls, you open the lower level floor plan view. Select the Wall tool again, and use the Type Selector to specify the desired wall type. The height is set to go up to the next level, and the Chain option is cleared. Note the Location Line of the wall is set to be the wall centerline. The walls are then placed using the temporary dimensions to help with positioning.
To create an opening for the hallway, you use the Split tool and split the wall into 2 separate segments at the point where the opening is needed. Next you use the Trim tool, selecting the portions of the walls which are to be kept, thus cleaning up the opening for the hallway. Next, in the Project Browser, you double-click the 02 Entry Level floor plan, opening this view so that interior walls can be added to the upper floor.
