2D Patterns - Circular Fill not showing as circle 1

[johnathamilton]

I am trying to create a 2D pattern for a screen printing operation - the pattern includes a large radius ring segment of 3 mm thickness. I need to fill the face to create a dark enough image on the draft. However when I do this, the nice smooth edges become 5 straight lines that approximate the curve. I've tried increasing the hatch line density but to no avail. Does anyone have any insight on why this is happening and what it will take to fix it? I would like to have as smooth a radius as possible.

thanks
John

Have you actually applied a 'fill' or just cross-hatching?
If you are using ST click the Fill Colour button and make sure the fill is on. Also set the colour to same as Pattern Colour.
I can't remember what it's like on V20 etc but you are looking do the same thing.

Where would we be without sat-nav?

Thanks BC - I am using ST on a Core2 Duo machine with an Nvidia Quadro FX 2700 video card.
I went in to the part file and ensured the colours were the same for the fill and hatch. Also went into the Styles definitions in both the part and the draft files and set the line width to black, 0.1 mm thick and 0.1 mm spacing. Also set the resolution on the part view to 300 pixels per inch.
I also tried rotating the part view before placing onto the sheet.

So far it still looks the same. It appears to me that there is a fill limit issue ie. the boundaries for the fill/hatch are not updating to a higher number of segements to approximate a circle and the hatch just goes to these boundaries and stops. If I use the shaded with Visible Edges option, there is a gap between the lines and the hatch.

A bug perhaps?

Thanks again for your help..

Hi,

SE fills the gap between the hatch lines. I tried to fill the
the face by setting the hatch to a wide spacing (60 mm). The
result when saved out as .pdf was OK even when setting the
maginfication to 2000% (see attached image)
The arc's radius was set to 2500 mm; all done in 2D
