Define Contour Hatching (2-D)

2-D Part > Hatching > Def. > Contour Hatching, Define

In contour-based hatching, the interior of closed polylines is hatched; the graphical elements can, however, belong to different parts.

After activating the Contour Hatching, Define function, you can choose between two contour types.

• Hatch surface (1)
• Hatch existing contour (3)

(1) Hatch surface
(2) Contour identification point
(3) Hatch existing contour

This hatching uses the contour determination algorithms for defining the contour to be hatched and does therefore not depend on the existence of internally contiguous polylines in a part.

To define the contour, you need to specify a contour identification point. The identification point determines the contour's initial graphical element.

If there are no other elements in the interior of the contour, you can choose any point in the interior as the contour identification point. Typing in the area to be hatched enables you to obtain the hatching.

The hatching can consist of lines or symbols:

• For lines, you choose the Hatch contour function 
• For symbols, you choose Pattern contour from the symbol table.

A hatching reference point containing all hatching information is created for each hatching.

In the case of an exclusion, you also need to specify an identification point for the exclusion contour. If there are several exclusion contours, they all need to belong to the same part as the hatching.

In the case of texts and dimensionings, the corresponding hatching exclusion points are automatically placed in the part. You need to place the hatching reference point that belongs to these exclusions in the part containing the text or the dimensioning.

In the case of clonings that affect a hatching element, the corresponding exclusions are handled with the same cloning type. With clonings, it makes sense to place hatching and exclusion elements in the same part.

Hatch contour

2-D Part > Hatching > Def. > Define > Hatch contour

1. Activate the contour hatching type and then the Hatch contour icon.

The mask containing the hatching parameters appears as for part hatching.

2. Specify the hatching parameters and exit the mask with Hatch.
3. Now identify the contour.

Please note:

If you activate the Cut surface option in the Hatching Tool dialogue, you are additionally offered a cross-hatching (plastics).

Pattern contour

2-D Part > Hatching > Def. > Define > Pattern contour

The internal surface of the identified contour is assigned a pattern.

1. Choose the pattern you want from the symbol table.
2. Specify the spacings in x- and y-directions.
3. Select the contour, and define the pattern point.

Hatching parameters

2-D Part > Hatching > Def. > Define > > Hatching parameters

You can specify the various hatching attributes like line type, layer, colour, angle and hatching line spacing separately before selecting the contour.

1. Set the parameters.
2. Press Continue to exit the pop-up menu and identify the contour.

Patterning parameters

2-D Part > Hatching > Def. > Define > Patterning parameters

The menu functions enable you to set the pattern parameters of layer, symbol angle, stretching factor, edge spacing and symbol spacing.

1. Select the symbol.
2. Set the parameters.
3. Choose Continue to end parameter setting and identify a contour.
