It always gets me that we have the opportunity to make our drawings so much more presentable yet people still want dull old black and white cad. Much prettier, less confusing and way more obvious than the traditional single diagonal line. Or you could use different hatch patterns, go through the colours of the rainbow, whatever suits you. We use shades of grey (solid and transparent, looks like shading) - lighter to darker at each level, as you ascend. You could also use a different ceiling type for each level and filter that way. Being text based it requires monitoring but it works for us. Then created a filter and added it to our RCP view template to override surface pattern graphics for each level of ceiling, based on your text parameter value. I am attaching a screenshot of the Problem. When I open the pdf in another PDF viewer (Sumatra) they aren't there. What we have done is add an instance based text project parameter to the ceiling category. I just tried to plot a drawing to PDF and when I open it in my PDF viewer (Xodo) there is one grey, thin, diagonal line going across the hatch. The preceding example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler.Most of the ceilings are some sort of grid pattern which need to align with other things within the room so unfortunately we don't have the freedom to move the hatch as we please.I agree with Steve but we go a bit further. The following illustration shows the filled ellipse.Į.Graphics.FillEllipse(hBrush, 0, 0, 100, 60) Į.Graphics.FillEllipse(hBrush, 0, 0, 100, 60) There are more than fifty elements in the HatchStyle enumeration a few of those elements are shown in the following list: The hatch style argument can be any value from the HatchStyle enumeration. The HatchBrush constructor takes three arguments: the hatch style, the color of the hatch line, and the color of the background. The following example demonstrates how to fill an ellipse with a hatch pattern: Example To fill a closed shape with a hatch pattern, use a HatchBrush object. A hatch pattern is made from two colors: one for the background and one for the lines that form the pattern over the background.
