This section introduces the presentation options for showing parts and neighbor- ing parts in drawing views.
Part representation
You can control the appearance of ordinary and neighboring parts independently:
• To control the appearance of parts, click Part... in the drawing proper- ties dialog box.
• To control the appearance of neighboring parts, click Neighbor part...
in the drawing properties dialog box.
When you edit a schema file, you do not need to re-open the model for the changes to take effect. Just open a different type of drawing. Then open the original drawing and hatches are updated. Tekla Structures always reads the current schema file when the drawing type changes.
The options on the Content tab define the appearance of parts in drawings.
Part
representation
The Part representation list box gives you the following options:
• Outline
Parts appear as solid objects in drawings
• Exact
Parts appear as solid objects, Tekla Structures also draws the chamfers in profile cross sections
• Workshop form
Tekla Structures draws round tube profiles as wrap-around templates
• Bounding box
Parts appear as boxes which surround the actual profiles
• Base box
Tekla Structures shows parts as boxes and uses the h and b values from the profile catalog as box dimensions
Symbol offset Defines the distance of the endpoints of reference lines and centerlines from the
Hidden lines Defines the appearance of hidden lines in drawing parts.
• Hidden lines
Shows hidden lines in secondary and neighboring parts
• Own hidden lines
Shows hidden lines in main parts
Centerlines Use to switch the centerlines of parts on or off. You have the following options:
• Centerline
Select checkbox to show centerlines
• Main part
Select checkbox to show centerlines in main parts (Beam, Plate or Polygon)
• Secondary part
Select checkbox to show centerlines in secondary parts (Beam, Plate or Poly- gon)
Reference lines The reference line is a line between the points from which a part is created. You can switch part reference lines on or off. You have the following options:
• Reference lines
Select checkbox to show reference lines
• Main part
Select checkbox to show reference lines in main parts (Beam, Plate or Poly- gon)
• Secondary part
Select checkbox to show reference lines in secondary parts (Beam, Plate or Polygon)
Appearance For information on how to control the appearance of objects, see Common drawing object properties (p. 181).

Orientation marks
Orientation marks indicate the erection direction of assemblies. You can indicate orientation using:
• Mark location
• Compass direction (only for columns)
• Orientation symbol
Mark location
In general arrangement drawings part marks appear at the same end as in assem- bly and cast-unit drawings. Parts with the same assembly or cast-unit position are always marked at the same end.
To indicate orientation using mark location:
1. In the assembly or cast-unit drawing properties, click View... > Attributes and set the Coordinate system to oriented or model.
2. In the Model Editor, click Setup > Numbering... and clear the Beam orienta- tion checkbox.
3. Create assembly and single-part drawings, or cast-unit drawings.
4. Create general arrangement drawings.
When you update an assembly drawing or a cast-unit drawing, remember to update the marks in the corresponding general arrangement drawing. Tekla Structures does not do this auto- matically.
Compass direction
Part marks include the face direction. Tekla Structures only indicates the face direction if it is the same for all assemblies or cast units with the same assembly or cast-unit position number.
To indicate orientation using compass direction:
1. First check the orientation marking settings (project north etc.) in the Model Editor. To do this, click Setup > Options... and the Orientation marking tab.
See Setting up orientation marking (p. 144).
2. In the Model Editor, click Setup > Numbering... and select the Column orienta- tion checkbox. This forces Tekla Structures to show the face direction in the part mark for two similar columns with different orientation.
3. In the assembly or cast-unit drawing properties, click Part mark... and include the Face direction element in the part mark.
4. Create assembly or cast-unit drawings.
Face direction indi- cates the compass direction (North, East, South, West) of the face where the mark appears.
Orientation symbol
Orientation symbols indicate the erection direction of assemblies. The default orientation symbol is a triangle inside a circle.
To add orientation symbols to a main part:
1. In the assembly drawing properties, click Part... > Content and select the Ori- entation marks checkbox.
2. For different parts, Tekla Structures draws orientation symbols:
• To the top flange of beams, at the end which points closest to North* (see part 1 in the illustration above)
• To the lower end of columns, on the flange which points closest to North* (see part 4 in the illustration above)
• To the flange of bracing, at the end which points to closest North* (see part 3 A in the illustration above)
* or to another designated point of the compass.
Connecting side marks
You can add a user-defined symbol to mark the side of a part to which a connect- ing part is attached. In the assembly drawing properties, click Part... > Content and select the Connecting side marks checkbox.

Setting up orientation marking
To set up orientation marking in the Model Editor, click Setup > Options... and then the Orientation marking tab.
Field Description
Project north Defines which direction is North in the model.
Enter the value in degrees counter-clockwise from global x axis.
Part viewing direction Defines from which direction parts are viewed in drawings.
Beam skew limit Column skew limit
Tekla Structures uses limit angles to determine whether a part is a beam or a column when creating orientation marks. Tekla Structures treats parts out- side these limits as braces.
Preferred location for mark
Defines the location of part marks in drawings, to the left or right end of the part.
Mark always to center of column
This setting only affects columns.
Yes places part marks in the center of columns in plan views. To indicate part orientation, use com- pass direction in the part mark instead. See Com- pass direction (p. 142).
No places part marks on the same flange in GA drawings and assembly drawings.
NORTH
Parts skewed less than 10° are beams
Parts skewed more than 80° are col- umns
