You can draw room elements by Point, Line (straight line and arc) and Rectangle. If there are enclosed areas, you can use the method of Point. The enclosed areas are formed by walls, curtain walls and kerbs. You can use the method of Line or Rectangle when there are non-enclosed areas, or when there is no main structure elements.

Elements attached to room
1) Under Room, you can create attached elements, such as floor finish, skirting, wall finish, ceiling finish and suspended finish. You can create an attached element, or add an existing attached element. As shown below, you can use the first button to create an attached element, and use the second button to add an existing attached element.

2) You can modify the attached elements that you added to other attached element. As shown below, double-click the existing attached element, FF-1, and the in the list of all existing elements, select one element to modify.

3) You can view and modify the attributes of attached elements. To modify the attributes of a specific finish entity, there are several ways:
a. Go to the corresponding element, for example, Wall Finish, select the entity, and then modify its attributes in the Attribute Editor.
b. Go to Room, click Cross-Layer Select, select the finish entity, for example, Wall Finish, and then in the Attribute Editor that is shown in red box below, modify the attributes.
c. To modify the attributes of all entities of the element, you can modify them in the Attached Element Attribute that is shown in blue box below, click Refresh, and then select the corresponding finish element.

Room Elevation
1) When creating room elements, the elevation is Bottom Slab Top Elevation by default, and the slab with the greatest elevation in the range of bottom slab will be found. To modify the slab finding range, click Welcome > Options > Slab Finding.
2) If the default value fails to meet layout requirements, you can modify the elevation of room to others, for example, Floor Bottom Elevation.

Regenerate Finish Entity

If the elements attached to rooms change, you can use Regenerate Finish Entity to update the room entities that you have already laid out. The basic principle of regeneration is to delete the existing rooms and corresponding attached finish entities first, and then lay out a new room element.

Note

If only part of the attached elements of specific rooms change, you’d better just select the changed rooms and elements, so as to get a better efficiency than selecting all rooms and attached elements.
