Add hatches (fills) to parts in drawings

You can use hatches as fills in parts, neighbor parts, and cross sections in a drawing. You can use automatic hatches or manual hatches.

Limitations

There are some limitations in the hatch background color usage:

Background color does not work in conjunction with hardware hatches.
The background color does not have any effect if there is an automatic hatch available. The background color can only be changed if the automatic hatch is not defined for the material type.

You can also use fills in sketch objects (rectangles, polygons, circles). For more information, see Draw sketch objects in drawings.

To add a fill to a part:

On the Drawings & reports tab, click Drawing properties and select the drawing type.
Load drawing properties that are as close to the ones you need as possible.
Single-part, assembly and cast unit drawings: Click View creation in the options tree on the left, select the view and the properties that you want to change, and click View properties.
Click Part and go to the Fill tab.
Select the hatch from the Type list. Select Automatic or a manual hatch pattern.

To preview the hatches, click the ... button next to the Type list.

You can select the desired hatch by double-clicking it in the Hatches window.

If you select Automatic, Tekla Structures uses the hatches defined in the hatch schema file (.htc). Each drawing type has its own schema file.

The names of the schema files Tekla Structures are defined in the Hatching category of the Advanced options dialog box:

XS_DRAWING_GA_HATCH_SCHEMA

XS_DRAWING_CAST_UNIT_HATCH_SCHEMA

XS_DRAWING_SINGLE_PART_HATCH_SCHEMA

XS_DRAWING_ASSEMBLY_HATCH_SCHEMA
Define a color for the hatch in the Color box.
Define a background color for the hatch in the Background box.

You can define the background color only after selecting a hatch first.
In Scale, select whether to use automatic or custom scaling and rotation for hatches.
If you select automatic scaling and rotation, Tekla Structures automatically scales the hatch to suit the profile size, and you do not need to edit each drawing manually. If you select Custom scaling and rotation:
- Enter the scales in Scaling in direction x and Scaling in direction y, and select whether to Keep ratio of x and y.
- Enter the angle of rotation in the Angle box. Angle 0.0 is for horizontal and 90.0 for vertical.
Single-part, assembly and cast unit drawings: Click Save to save the view properties. Then return to drawing properties by clicking Close.
General arrangement drawings: Click OK to return to drawing properties.
Click Save to save the drawing properties, then click OK and create the drawing.

Example 1

In the example below, the following hatch options have been selected for cross sections:

Scale: Custom

Scaling in direction x: 0.25

Scaling in direction y: 0.50

Keep ratio of x and y is selected.

Angle: 10.00

Cast-in-place and precast hatches use different automatic hatch depending on the cast unit type. You need to select the appropriate cast unit type in the concrete part properties.

Note:

If the hatches are not displayed in the drawing, check the session history log for the following messages:

"Solid warning: Clipped part Id: XXXX was created with second fall back and may contain overlapping volume and area."

"Solid warning: Pour Id: XXX was created with second fall back and may contain overlapping volume and area."

Usually it is enough that you move a part or a cut a little bit, maybe 1 mm, in any direction.

Example 2

You can use the following fill types to represent insulation:

These hatch types can be scaled and rotated.
