Jared's response is correct. Click "Edit Object Parts" button and you will be able to select and delete one segment of a polyline.

Note: If it is a "box" and not a "polyline" you will not be able to delete one side. They are different types of objects.

DoubleCAD had a free version that I use to preview and make minor edits to dwg files.

2009 I codes for us.

I have never had an issue with code compliance that I can attribute to software.

I can do cheesy animations on my own, thank you.

I use BullZip PDF

where's the image?

Windows Key-Tab will show you all the open applications on a PC. You can tab through them or select the on you want with the mouse.

I would go with the pocket door. (Though my wife does remind me occasionally regularly that she's surprised I'm still married.)

Excellent summary by Joe Carrick cut & paste from the "legacy forum":

Fill Patterns are simply text files that can be edited in a simple text editor like Notepad. Chief Architects supplies some standards and several custom patterns that are contained in the "Pattern" folder. Each Pattern is made up of a series of Lines.

The format of a Pattern File is as follows:

;; PATTERN FILE NAME.PAT
*1-PATTERN_NAME
nAngle, xOrigin,yOrigin, xRepeatDelta,yOffset, [nLength,nSpace]
.................................................. ......
.................................................. ..
.................................................

nAngle = Angle of the Line (0 is horizontal - angles are measured clockwise)
xOrigin,yOrigin = Start Coordinates of the Line
xRepeatDelta = Offset of the Repeat Pattern (only valid when nLength & nSpace are present)
yOffset = Spacing between Lines
nLength = Length of a Line (if not provided the line is continuous)
nSpace = negative value indicates length of a space.

Example Pattern:

*CEILING_GRID_24X48
0, 0,0, 0,24
0, 0,1, 0,24
90, 0,0, 0,48
90, 1,0, 0,48

This results in a pair of horizontal lines 1" apart repeated 24" o.c.
and a pair of vertical lines 1" apart repeated 48" o.c.

In most cases xRepeatDelta will be 0.
If a specific length solid line and spacing is needed then [nLength,nSpace] should be specified as nLength,-nSpace such as 23,-1 to result in a line 23" long with a 1" space before the next solid line.

Note that the above is very similar to the AutoCad format but Chief doesn't support a DOT in the Line definitions
