Freehand elements


With freehand tools you'll be able to draw any kind of structure. You can event import them from a dxf file.

In order to create a freehand element you've to follow two steps:


1- Generate lines defining its structure

Using the tools shown in the following picture, you can draw and modify lines and arches:



Create a simple line; click on first point an then on second point.

Create a line strip; click on every point of the strip and right click or double click to terminate.

Create a rectangle; click on first corner and then on second corner.

Create an arch. There are three modes:

1- click on first and second point and then define radius by moving the mouse;

2 - hold down the CTRL key, click on the center of the circle and, while still holding down CTRL, click on a second point to define the radius of the circle to create;

3 - hold down the CTRL key, click on the center of the circle, release the SHIFT key and click on two points to define the arc.

Create a layered structure.

Cut a line.

Remove a line.

Move lines; first you must select vertices by clicking on them (hold down CTRL key to add to selection) or by dragging a selection rectangle.


2- Fill areas with transmittance properties

With the following tools you'll be able to define transmittance and linear transmittance properties of the various areas of the element:




Fill area with the properties of a material. To assign a material you need to click in the middle of the desired area on the viewport.



Remove the properties of a material from an area.



Remove the properties of a material from a segment.



Modify the properties of an area. Simply click on an area, modify its properties and press "Ok" button. If "Apply to materials with same name" is checked, changes will be applied to every material with this name; the same applies to "Apply to materials with the same color or texture".

If "Apply thickness to all materials is checked, current material's thikness will be set to every project's material.



Read the properties of a material clicking on an area.


It is possible to manage library materials through the appropriate button. Thanks to the window that will pop up, you can also load and save parts of the library; in particular, you can use .csv files. These files should be structured in the following way:

Type (0 = transmittance material, 1 = psi material), name, red color (from 0 to 1), green color (from 0 to 1), blue color (from 0 to 1), transmittance, linear transmittance.
