A Sraffozás parancsok lehetővé teszik zárt területek vonalakkal, különböző mintákkal való sraffozását. Mielőtt sraffozná a kívánt területeket, állítsa be a sraffozás globális tulajdonságait.

Commands:
Hatch - Pick Point + island.
Inserts the hatch within a closed area that is bounded by one or more objects. With this method, you click within the boundaries to specify the area.
Enclosed areas inside hatch boundaries are treated as islands.
Every island inside the area will not be hatched. Island detection only goes one level inside, so the program does not search for islands inside the islands.
Hatch - Pick Point.
Inserts the hatch within a closed area that is bounded by one or more objects. With this method, you click within the boundaries to specify the area.
Imaginary polygon
Inserts the hatch within a set of objects with endpoints that touch and enclose an area.
Imaginary polygon with islands
Inserts the hatch within a set of objects with endpoints that touch and enclose an area. Every closed chain of lines (island) inside the area will not be hatched. Island detection only goes one level inside, so the program does not search for islands inside the islands.
Hatch 3D - Pick point
With this command you can add hatch to a selected 3D plane. To do so, you have to specify the origin and the direction of the hatch.
Hatching 3D planes:
• Select the plane of an object, which you wish to hatch.
• Define the origin of the hatch on the selected plane.
• Specify hatch direction.
Select boundary
Inserts the hatch within a closed area whose objects you select one by one.
Text frame search on/off
This chckbox you can turn on or off. If you enable the option Text boundary, the program creates a boundary in the hatch pattern for the measurements, arrows and texts so that these are easier to read.
Hatch types:
| Type | Description |
| Predefined hatch patterns | Choose from many ANSI, ISO, and other industry-standard hatch patterns |
| User-defined hatch patterns | Define your own hatch patterns based on the current linetype, with spacing, angle, color, and other properties you specify. |
| Autocad .PAT files | You can import hatch patterns that are defined in the acad.pat files. |
| Solid fill | Fill an area with a solid color. |
| Gradient fill | Fill an enclosed area with a color gradient. A gradient fill can be displayed as a smooth transition between two colors. Geometry can be linear. central, conical and quadrant. |
| Material | Choose a material from the library. |
Hatch properties
| Type | Description |
| General properties | Colour, line width, line thickness, layer and priority |
| BIM parameters | |
| Type | See above |
| Angle | Direction of the hatch lines in angles (relative to the horizontal direction). |
| Spacing | Line spacing of the hatch (in drawing units). The distance between the hatch lines is to be understood perpendicular to the hatch direction (y direction). |
| Dash length | Line spacing of the hatch (in drawing units). The distance between hatch lines is to be understood parallel to the hatch direction (x direction). |
| Background colour | Background colour for the hatch. By default, there is no background colour. |
| Transparency | This means that both the hatch background colour and the solid hatch are transparent. Transparent hatches always have pale colour. |
Hatch boundary
You can set whether to show the hatch boundary or not.
This option can be very useful when adding hatch to an area enclosed by a polygon boundary. The hatch boundary has its own properties.
| Type | Description |
| General properties | Colour, line width, line thickness |
| Show hatch boundary | On or Off |
IFC correspondence
Specifies how to convert the geometry to IFC element.
Operations with regions
With the commands of the Operations with regions you can unite or extract hatches, add hatch to the common part and omit this part from the hatch:
Union
Unit the selected hatches. The hatches selected afterwards will have the properties of the hatch selected first.
• Select the hatches to be united, or the closed objects whose contours you wish to unite for hatching.
• Enter Completes the selection and unites the hatches
Extract
Extract one from the other of the selected hatches. Select a hatch and the program extracts from this the hatches selected afterwards.
• Select the hatches to be extracted.
• Enter Completes the selection.
Intersection
Create a common part (intersection) of the selected hatches. The hatches selected afterwards will have the properties of the hatch selected first.
• Select the hatches or closed objects whose intersection you wish to create.
• Enter Completes the selection.
Omit intersection
The program creates the „symmetric difference” of the selected hatches. This means that it produces a common part, and then omits it from the union of the hatches. The hatches selected afterwards will have the properties of the hatch selected first.
• Select the hatches or closed objects whose symmetric difference you wish to create.
• Enter Completes the selection.
