Edit Menu: Hatch

Hatch” is used to force EzCad to calculate the hatch fills for the current objects. The object to be filled must be closed curve, and if you choose many objects to fill, these figures can be objects nested mutually. Any two objects may not have intersectant parts.

When selected a hatch dialog box will appear.

hatch setting

Mark Contour: whether to show and mark the current object’s contour or not.

mark contour 1

means when click ‘Mark Contour’, mark hatch line first then mark contour.

mark contour 2

means when click ‘Mark Contour’, mark contour first then mark hatch line.

Hatch 1 / Hatch 2 / Hatch 3: Users may have three independent hatch parameters to hatch the same object at the same time. Each set of hatch parameters can be appointed a Pen No. which stands for a set of marking parameters.

Enable: whether to permit the validity of the current hatch parameter.

All Calc: Calculate all the selected objects as a whole. This is an optimizing option. In some cases the speed of marking may highly be raised. It will take long time to calculate large, complex objects. When not selected, the objects will be calculated separately.

For example: draw three rectangles, line distance is 1mm, angle is 0.

1.Do not click ‘All Calc’, system will mark as the order in object list, mark hatch line in the first rectangle then mark hatch line in the second rectangle, and so on.

2.Click ‘All Calc’, mark all the hatch line at one time, mark all the hatch that on the same line.

3.Marking result as follow fig.

do not click ‘All Calc’

do not click ‘All Calc’, the hatch line are not in the same line.

click ‘All Calc’

click ‘All Calc’, hatch line are in the same line.

Type of Hatch:

Click the button will switch between the following types of hatch.

Unidirection hatch

Unidirection hatch:

The hatch lines will be marked from left to right.

Bidirectional hatch:

Bidirectional hatch:

The hatch lines will be marked from left to right first, and then from right to left.

Ring-like hatch

Ring-like hatch:

Fills objects from the outside to the inside like a ring.

Optimization two-way hatch

Optimization two-way hatch:

Similar with bidirectional hatch, but the end of each end connects.

Optimization Gong type hatch

Optimization Gong type hatch:

Similar with Gong, will jump in null place.

Angle: Hatch Angle stands for the angles between hatch lines and X axis.

Line Distance: the space between two hatch lines.

Average distribute line: The solution the starting and ending hatch line are non-average distributes question when the object is hatched. After select this item, the software automatic adjust the hatch line space in the user setting hatch line space foundation, will let the hatch line average distribute.

Edge offset: the distance between hatch lines and the object’s outline.

Start Offset: the distance between the first fill line and the border of the objec

End Offset: the distance between the last fill line and the border of the object.

Linereduction: The hatch line both sides reduction.

NumLoops: The times of Ring-like hatch before the aclinicing hatch.

Auto rotate hatch: Refers to after every marking, the hatch line will fill the revolving angle which we setted automatically to marking again. For example, angle is 0, auto rotate angle is 30, the first mark angle is 0, the second is 30, the third is 60, and so on.

Hatch one by one: choose multi object and hatch together, after hatch, still independent object.
