example009.scad preview different from render #5238

Closed chartan1990 closed 3 months ago

chartan1990 commented 3 months ago

Describe the bug Clicking on "Render" produces a different image on the Viewport, as compared to clicking on "Preview" button. Error-Log gives a warning: File: ./OpenSCAD/examples/Old/example009.scad Info: Can't open DXF file 'example009.dxf'!

To Reproduce Steps to reproduce the behavior:

Installation: https://files.openscad.org/OpenSCAD-2021.01-x86-32-Installer.exe And then follow all the steps on the installer.

  1. Launch the application

  2. Click on "File"

  3. Mouseover to "Example"

  4. Mouseover to "Old"

  5. Click on "example009.scad"

  6. Click on "Preview" button, notice that there is a translucent box around the golden fan: example009_err_preview_button

  7. Click on "Render" button, notice that the translucent box is no longer around: example009_err_render_button

Expected behavior I expected "Preview" button and "Render" button to be the same.

Code reproducing the issue `echo(version=version());

bodywidth = dxf_dim(file = "example009.dxf", name = "bodywidth"); fanwidth = dxf_dim(file = "example009.dxf", name = "fanwidth"); platewidth = dxf_dim(file = "example009.dxf", name = "platewidth"); fan_side_center = dxf_cross(file = "example009.dxf", layer = "fan_side_center"); fanrot = dxf_dim(file = "example009.dxf", name = "fanrot");

% linear_extrude(height = bodywidth, center = true, convexity = 10) import(file = "example009.dxf", layer = "body");

% for (z = [+(bodywidth/2 + platewidth/2), -(bodywidth/2 + platewidth/2)]) { translate([0, 0, z]) linear_extrude(height = platewidth, center = true, convexity = 10) import(file = "example009.dxf", layer = "plate"); }

intersection() { linear_extrude(height = fanwidth, center = true, convexity = 10, twist = -fanrot) import(file = "example009.dxf", layer = "fan_top");

rotate_extrude(convexity = 10) import(file = "example009.dxf", layer = "fan_side", origin = [0, -40]); }

The translucency here is done using the debug modifier (% on lines 9 and 12) it is expected that the transparent elements will not show in a full render. https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Modifier_Characters#Debug_modifier details this behaviour. I am not seeing the missing file prompt when running with either the latest release version as you have documented or the nightly builds.
