scale. A color position on the hatch transition scale is indicated with a triangular marker below the scale.
Using the marker, you can set the new position of the color on the scale. To do this, point to the desired
marker, depress and, while holding the button down, drag the marker to the desired position.
To delete a color from the transition scale, drag its marker out of the scale. To modify one of the
transition scale colors, double-click on the respective color marker.
You can also use the context menu accessible by right clicking on the scale image in order to set up
the color transition scale.
A color scale setting can be saved into an external file “*.col” in order to quickly load it in the future.
An additional parameter “Angle” defines the fill rotation angle.
Circular. This is a fill with a circular color transition. Its parameters are similar to those of a fill with the
linear color transition, except for the fill angle (it is not defined for a circular hatch).
You can define the center of a fill with a circular transition. To do this, when editing such a field,
define its start point. For details, refer to the section “Editing Hatches and Fills”, the topic
“Defining the Hatch Start Point”.
Filling pattern parameters
With this area filling method, the hatch type is defined by a description stored in a file of a special format.
The descriptor file of the standard T-FLEX CAD hatches is stored in the “PROGRAM” folder under the
name “TCAD.PAT”. The name of the standard hatch pattern file is defined in the command
“Customize|Options…”.
The same format is used for the hatch pattern descriptor file as in AutoCAD system. If some type
of hatching is not available, it can be created by the user or copied from AutoCAD system.
In the cases when standard hatches do not suit the user, then user-defined hatch types can be created. Special
format files “*.grb” are used for the user-defined hatch descriptors. These files are located in the
…/Program/HatchPatterns folder. More on this is in the chapter “Creating user-defined lines and hatches”.
The additional parameters of filling by pattern include:
Type. Defines the filling pattern. The type is selected from a list
containing standard and user-defined hatch types.
Size. Defines the scale factor of the pattern hatch. With a very small
scale factor the hatch may appear as a solid fill.
Angle. Defines the slant angle of the hatch.
Line thickness. Defines line thickness, used when drawing a hatch by pattern.
