The Auto Take-Off tool is used to shade areas of an imported blueprint and then convert the shaded areas into rooms. This feature can eliminate the need to meticulously trace the outlines of rooms on some blueprints.
How To:
-
Left-click the "Take-Off on Blueprint" button, which can be found under the "Blueprint" tab of the Ribbon Bar.
-
Create barriers in doorways and other areas where natural room boundaries are not present on the drawing.
- Adjust Auto Take-Off parameters such as line weight and grey level in order to match with the properties of the imported blueprint image.
-
Left-click a space on the imported blueprint that should be designated as a room. Repeat this process for each room.
-
Click the "Create Room(s)" button or press Enter to convert the shaded areas into rooms.
The "Take-Off on Blueprint" Window
Shade Area Measure will attempt to detect walls based on the color difference between them and the lighter background of the blueprint. If an area on the blueprint is not fully enclosed with distinct boundaries, shading can spill over to surrounding areas. Use the Barrier feature to negate this. Tip: Hold down the left mouse button and drag the cursor for a continuous fill. This can be useful on blueprints with a great deal of text or other noise that Measure may interpret as room boundaries. |

Create Barrier Barriers are used to limit the extent to which an area is shaded. In the accompanying image, the door swing indicator has prevented a portion of the bedroom from being covered. A barrier is placed in the doorway so that area can be shaded without it spilling over into the hall. |

Create Room(s) Areas that are solidly shaded, without any breaks, are generated as a single room. An example of this can be seen in the accompanying image. Because there were no walls or barriers between the bedroom and closet it was generated as a single room. If a barrier had been added in the doorway between them, they would have been rendered as two separate rooms. |

Ignore Features Smaller Than In the accompanying image, this option was set to match the thickness of the major interior walls. The result is that even though the walls between the bedroom and closet were not shaded, they were still included in the area of the room because their width was less than the size entered in this field. |

Snap Wall Angles to Multiples of Note: If an entire room is at a non-right angle, the system will use the dominant direction of the room as the basis from which the angle snapping occurs. |
