Looking For Help? / Using *.png images
« Last post by jym_ing on June 16, 2017, 11:46:10 PM »
Dear DesignCad experts,
When I load png images, the background is opaque (like jpg); how can I get the background transparent?

Thank you

(using DesignCad Max 24)

How about simply View --> Ruler   ;D

Of course you have to be in 2D mode!

Also, you if printing from a pdf, you can increase the dpi to make 0 lines visible (all the way in Advanced via the many printer setup buttons, at 144 dpi they invisible)

Right click the status bar at the bottom of the screen or any visible toolbox, or right-or-left click an empty space in the menu bar and click 'ruler' from the popup menu.

Try running "sys(229)=0" (no quotes) on the command line.

Basic question: How do I turn the Ruler option on? In my View pulldown, "Ruler" is not selectable.

Bdeck,
in such cases, instead of increasing dimension line width, simply, increase the Pen Width  in "DesignCAD Print Command" Windows, found in Type tab.
Because when you need to increase dimension line width, I suppose you have to increase Hatch line width too (which are the sames...)
 ;)

Another trick to be able to zoom back to a known extent is to open an empty layer and draw a line from one side of the window to the opposite side. Then never put anything else on this layer.

Make this reference layer the active layer, hide all other layers, and use "View/Fit to Window" (CTRL W) to zoom so the line spans the window. Then resume drawing on other layers.

Why bother? Since DesignCAD is a vector program lines (everything) are defined by a formula and not by pixels. Consequently, the zoom factor has nothing to do with the resolution of the vector drawing.

But this has significant consequences if you load a raster image into DesignCAD. It is loaded at whatever pixel resolution your screen display is at the time you load the image. So if you load the same image file several times, at different zoom factors each time, the resulting images will be different sizes relative to the vector portions of the drawing.

This can cause severe headaches if you want to load several images at the same pixel scale - say you have multiple scans of a long drawing and you want to load them to appear as a single large image. If you do not establish a zoom reference and use it before each image file load the images will not be at the same scale.

So use the reference line to set the zoom scale before loading each image and they will all have the same pixel density.

Also remember that you can at any time change the origin (0,0,0) of the drawing and the ruler will reflect this change.

Remember that the screen is sort of an opening through which you view all or part of your drawing.

Designcad does not work within "limits" as do some other cad programs.

You can draw lines of any length, on screen or beyond, and if you do a zoom extents (Ctrl+A) the screen will expand to show you the largest entities you have drawn.

In theory, if you were to draw a 50 unit line starting at the centre of the screen, and zoom to its extents, the ruler should show something like 25, 75.

Thus, the ruler cannot really be fixed, as it represents a specific portion of your drawing ie 50 units when you start, but as you zoom in and out, it will tell you how many units of drawing you are currently looking at.

One way to ensure you can always zoom back to your original screen size is to draw a rectangle 50 wide x proportion to suit your screen height, starting at 0,0 bottom left, and 50, xx top right.

As long as you draw only within that rectangle, a Ctrl+A zoom will always return you to your 50 unit ruler display.

Many of us myself included always draw with the ruler turned off.
