Precision Model

To get deep into architectural modeling, we must learn how to model with precision such that the models are in their right proportions. The easiest way to model with precision is to work with the Grid. Press CTRL key and hold follow by the transformation key. It also works on Vertices, Edges and Faces. The distance between these lines are one unit, which could represent 1m, 1cm or 1 inch. To change setting, use the View menu, located in the 3D View Header and choose View Properties if we need a smaller or larger distance. This will reveal a menu, with some options to change the appearance of the grid.

• Spacing: To set up the distance between the major grid lines.



• Lines: Controls the number of lines that are displayed in the 3D View.



• Divisions: Between the major grid lines, we have some division lines to make a more precise used of the grid. This option help to set up the number of division lines.
  


• Grid Floor: This option turns the visualisation for the Grid on and off.
  

Transforming with Precision

Applying transformations using numeric values.(e.g)we need to move an object just 4 units on the X-axis, use Transform Properties menu which allows us to give numeric values for all transformations. Press N key or from the OBject Menu, in 3D View Header. The table will show the following settings:-

• Loc X/Y/Z: Controls the position of an object. if we typed 3 in the Loc Y field, the object will move 3 untis in the y axis.
  


• Rot X/Y/Z: Controls rotation of an object.
  


• Scale X/Y/Z: Controls the scale of the objects.



• Dim X/Y/Z: The model bounding box is changed.

Layers
Blender has a layer system which allow us to manage the visible objects better. There are 20 layers on which user can place objects in, to put an object into a different layer, just select the object, and press M key. A small menu will appear, where we have to choose a layer to which to send the objects. To turn on or off Multiple layers, we must hold the SHIFT key while clicking on the layer buttons.

Create Walls with Rounded Corners
To create wall with rounded corners, use a tool in Blender called Spin, this will creat extrusions of an edge based on a rotation. First, user has to know the radius of the round corner as it will be easier to create an arc required for the wall. * Make sure the measurements are in right proportions else the object may not be perfect when Spin is applied.

Two parameters that user must set up, which are Degrees and Steps. Degrees determine the rotation angle for the Spin whereas the Steps determine the quality of the corner, high values creates a more perfect corner.(Try to use values above 12). When Clockwise button is on, Spin will rotates in that direction else when the button is off, it will change o ant-clockwise.

Object Center (Pivot)
The center of object is represented by a small pick circle. We can move the center point in three ways:- (under Mesh)

• Center: Place the object geometrical center at the object center position.


• Center New: Place the object center at the object geometrical center position.


• Center Cursor: Object center will be placed at the position of the 3D cursor.
  
  

Bridge Faces/Edge-Loops (Mesh Scripts Bridge)
This option connects two faces together in condition that the faces are exact parallels.
