Controlling the ACS Plane, Perspective Tools, and Roof building tools

Microstation >Triforma >Bentley >Architecture

1. Construct Wall [Place Wall Tool]

Shut down all windows except window view 3 (isometric view)
     Maximize View
Turn off Perspective Settings, Camera, Off
Find Triforma Primary Toolbox
Place Wall Tool (third down on right) pull out toolbar
Do not touch wall types, use default interior partition wall
Click off "by part" toggle boxes
Specify a Height and a Width
Icon indicating how wall is drawn
     Draw wall along middle of the wall
     Draw wall along left of wall
     Draw wall along right of wall
Click once in View 3, Click T of top construction plan, click once again to specifiy the wall distance. Then click right mouse once to verify selection
You continue wall by simply continue left click before you accept with your right click

2. Place a Rectangle on a Diagonal wall

Draw a diagonal wall using the Place Wall Tool
Select the Place Block Tool
Place a tentative snap on a corner of the wall
Select "O" for offset [places the Accudraw Compass at the selected point]
Rotate the ACS Plane so that it aligns with the wall surface
     Type in "RA" [make sure the Accudraw Coordinate box is highlighted]
     Place a tentative snap on the same corner of the wall [confirm with a left click]
     Select the opposite corner to establish the x-axis using a tentative snap
     Select the corner above the original corner to establish the y-axis
     The ACS Plane is now aligned with the wall face
Place a block on the wall

3. ACS Plane Controls

Naming | Recalling ACS Planes
     Type in "WA" [make sure the Accudraw Coordinate box is highlighted] to name and save an ACS Plane
     Type in "GA" [make sure the Accudraw Coordinate box is highlighted] to recall a saved ACS Plane
Auxiliary Coordinate Tools [Tool menu, Auxilary Coordinates]
     First Tool | aligns the ACS with an element
     Second Tool | defines the ACS by establishing three points
     Third Tool | aligns ACS with the selected view
     Fourth Tool | rotates the ACS along an axis according to the right hand rule

4. Quick Perspective Tool [at the bottom left of the view window]

Select the tool and click in a view
As you drag the mouse to the lower left corner of the screen, the perspective will become longer
"Set Active Depth" Tool [Tool menu, View Control] establishes the view depth of the perspective

5. Prepare to Manipulate Perspective Viewing using the Define Camera Tool

Open View window one and View window three
Tile the two windows (window>tile)
Fit View in Both Open windows

6. Define Camera Tool

Setting >Camera >Off
Change View back to Front elevation view
Tools>visualization>Rendering
     Select Define Camera Icon (third from the left)
     Select the View you wish to manipulate (view 3)
          Make Sure Continuous View updates and Display View Cone are both toggled on
     Camera Action >dolly
     Projection>Two Point
     Move around View by manipulating the View Cone Points
Other Options in View control
     Roll- camera rolls around a point
     Pan- pans across model
     Lens Focal Length- allows you to change between telephoto and wide angle focal lengths

[Architectural Convention is to use two point perspective to assure that all vertical lines remain parallel]

7. Build a Roof

Place a rectangle that is the shape of the roof
Place a line from the midpoint of the rectangle vertically to the height of the roof
Copy the line to the midpoint of the opposite side of the rectangle
     This establishes a ridge for the roof
Use a Smartline to connect the corners of the base rectangle to the top of the vertical lines, establishing two roof planes

8. Project Walls to Roof

In walls tool palette, third icon from the right end>Modify Form tool
Change the method over to "to shape"
Select the first icon in the Modify form tool
Grab the first roof edge (it will highlight)
Grab the second roof shape
Move the mouse away from geometry and click once on right mouse button to confirm the elements you will extend to
Click the left mouse once to initialize your wall selection that you wish to extend
Click on each wall segment, and the walls should extend themselves up to under the gabled roof line.
