1.     Top Questions and Solutions

1.1        General

Question 1 I cannot see the thumbnails for ZW3D files in Windows Explorer. How can I make it appear? Solution: Thumbnails are very useful for you to easily find out the file that you want by previewing the content without opening the files. zw3d_2020_q3_technical_report_1 The disappearance of some of the thumbnails may be caused by saving the files in the Root Manager. zw3d_2020_q3_technical_report_2 If you find that all the thumbnails disappear, even for the new files, then the reason is the failure of registering of dll.  The solution is to register the “z3Thumbnail_x64.dll” manually: Step 1: Search “z3Thumbnail_x64.dll” in the installation directory of ZW3D Step 2: Copy it to the folder “C:\Windows\System32” Step 3: Run “Command Prompt” by administrator Step 4: Input "regsvr32 C:\Windows\System32\z3Thumbnail_x64.dll" after “\WINDOWS\system32>”, like the below figure shows Step 5: Restart your computer and the thumbnails can be shown zw3d_2020_q3_technical_report_3Question 2 I have to work both in office and from home. How can I share the ZW3D configurations among different PCs? Solution: Since ZW3D 2020, we’ve provided a useful tool called “User Folder Manager”, which can be used to clear the whole user folder or just the custom configurations, and also the cache files by “Clear auto output files”. zw3d_2020_q3_technical_report_4 As for the configuration sharing, you can save the configurations you want to share by “Save current configurations”, and then load it on other computers to reuse by “Load backup configurations”. zw3d_2020_q3_technical_report_5Question 3: Does ZW3D support adding new fonts? How? Solution: Yes, ZW3D supports adding new fonts for both windows TTF files and CAD SHX files. For windows TTF files, you can just download them from the internet, and then double-click to install. Then you can use them in ZW3D. As for SHX files, you need to use the SHX Converter to convert them into ZW3D font files, as the below figure shows. After that, restart ZW3D to use them. zw3d_2020_q3_technical_report_6

Question 4: Can ZW3D read the material info from CATIA® files? Solution: Yes, ZW3D can read the material info from CATIA® files directly in the 2021 version. What’s more, ZW3D can read all the mainstream 3D CAD file formats, like Z3, CATPart, prt, asm, sldprt, par, ipt, sat, dwg, dxf, iges, step, x_t, 3dxml, x cgm,  obj, etc., as well as their attributes, including hidden components, suppressed components, hidden entities, user custom attributes, material density, etc. Please note that the user custom attributes can only be captured from parts, components and assemblies, instead of the shapes in them. Question 5: How can I make the used sketch hidden or turn it into an internal sketch automatically? Solution: In ZW3D, you can start with a shape feature like Extrude, then create a profile for the extruded model by a sketch. In this case, the sketch will be an internal one and hidden automatically. However, if you create a sketch first, and then generate a shape from the sketch, it will be an external sketch, which can be set as hidden in Document Awareness Toolbar >> Visibility Manager as the below figure shows. zw3d_2020_q3_technical_report_7zw3d_2020_q3_technical_report_8 If you want the sketch to be hidden automatically after being used, you can check the “Hide used sketch” option in Configuration, which prompts after clicking the gear icon on the top-right corner. Please note that this is only available in the newly released ZW3D 2021. zw3d_2020_q3_technical_report_9Question 6: Today I opened my assembly file, and I found that some of my components are not displayed. In the assembly tree, there are cross icons on some components as the below figure shows. Why and how can I solve this issue? zw3d_2020_q3_technical_report_10Solution: The cross icon means that the component is missing and cannot be found by ZW3D. The most possible reason is that the saving path of the component or the file/ object name has been changed. Once you encounter such a situation, take it easy. First, you need to check where you have put the missing components, and whether you have changed their names in Windows Explorer. If you figure out the new saving paths of those components, then make sure that they are included in the search paths, and the option “Auto Search” is turned on. Then you can follow the below steps: (1) Use “Change Component” to update the missing component. (2) If you want to update all the part files that using this component, you can batch update by Utilities->Find/Replace Name: Step 1: Select “Selected files” for Scope Step 2:  Add the search path Step 3: Set “File and object name” as Type in case that the file extension of your missing component is Z3PRT. Then you can start replacing. After that, re-open the assembly file, and click “Unsuppress” to let the missing components show correctly. By the way, it is strongly suggested to rename the part files in the assembly manager as shown below. zw3d_2020_q3_technical_report_11Question 7: May I ask why there is a lock before the “Drawing View” node in the tree of 2D sheet manager? zw3d_2020_q3_technical_report_12Solution: This lock icon means that the view regen is disabled. You can just go to View Attributes, and click the following icon to enable it. zw3d_2020_q3_technical_report_13

Question 8: Is there any way to generate better toolpaths for fillet face? I use Z Level to get the toolpaths and find that the surface is not high-quality enough when I manufacture it. Solution: Yes, ZW3D provides a new option “Drive Curve” for Z Level operation to get better toolpaths, improving the quality of surface processing. Here is an example. Using “Non-Uniform Cuts” >> “No”, you may get the below toolpaths, which are not ideal enough. zw3d_2020_q3_technical_report_14 If you switch to “Drive Curve”, you can find that the toolpaths are better, so that the quality of surface processing is higher. zw3d_2020_q3_technical_report_15
