Insufficient memory when printing

Q: Why does the “Memory is not enough” error message appear when I print drawings? How can I fix it?

A: The problem may be due to the configuration of your hardware and software. Usually, printing requires large amounts of memory, especially when printing large, high-quality images. The error message typically appears on PCs with small amounts of memory (RAM). To avoid the problem, close programs that are not necessary. In addition, consider adding more RAM to the computer, or even to the printer, if it takes additional RAM.

Printing/plotting occurs slowly

Q: Why is the printing very slow?

A: Generally speaking, the printing/plotting function works well in ZWCAD. But the speed may be affected by factors like using the printer over the network, printing large images, or the configurations of the computer.
An alternative is to plot drawings as PLT files, and then plot them on another computer to a HPGL-compatible devices using Batch Plot function.

Rendered images

Q: How do I plot rendered entities as images?

A: Follow these steps to render drawings in plots:
    1. Use the Render command to shade-render the entities in your 3D drawings.
    2. From the View menu, choose Render, and then Preferences.
    3. In the Render Settings dialog box, choose the Rendering tab.
    4. You can save the rendered image as a JPG file by clicking the Save Last Image button.
    5. Finally, you can plot the image.

Plots with hidden lines removed

 Q: Does ZWCAD support hidden-line removal plots?

A: ZWCAD supports hidden-line removal in plots. To plot 3D drawings with hidden entities removed, you should turn on the Hidden Plot option in the Plot dialog box.

About raster output

Q: How do I add more types of raster output?

A: ZWCAD supports many kinds of raster output, and you can add them through the Add-A-Plotter wizard. Additional raster formats may be available from the Internet; we have found that most of them work well with ZWCAD.

Use STB files for printing with ZWCAD

Q: How do I use STB files when printing with ZWCAD?

A: Plot tables come in two flavors. One is the traditional color-based plot table (CTB), the other is the newer style-based plot table (STB). A drawing file can use only one type of plot table, color-based or style-based.  At present, ZWCAD supports CTB files but not STB files.

Plot styles are property that can be assigned to objects and layers in STB-flavored drawing files. When set to ByLayer, objects inherit the plot style property from layers, just as they do with colors, linetypes, and lineweight.

(In AutoCAD, the PStylePolicy system variable specifies the plot style (STB or CTB) to be assigned to new drawings. The PStyleMode system variable reports the current drawing’s plot style: 1 indicates CTB, while 0 indicates STB. The ConvertPStyle command changes the type of plot style.) Since ZWCAD does not support STB, the commands mentioned in the above paragraph are not available for now. If you come across drawings that require STB files, you might be able to use the ConvertCTB command to change STB files to CTB files, and then open them in ZWCAD.

Customizing print styles

Q: How do I customize print styles?

A: You can modify Plot Style tables in ZWCAD. In the latest update to the program, you can modify many item of Style Properties as shown below, such as grayscale, linetype, and fill style.

 You can also save the changes by another CTB (color-based plot table) file name stored in your computer.
