Rhino 9 WIP freezes after imported pdf file (just 4 pages)

Hello,

If Direct3D is set, after imported a pdf file, Rhino won’t response, it just freezes.

Also it won’t import IMAGES which are in the pdf, is it known and expected?

4 pages and import settings are below:

Switching back to OpenGL it works like a charm.

I would like to keep the file as private so I’ve sent the file via:

https://www.rhino3d.com/upload

I’ve tried on Rhinoceros (9.0.25329.12305, 2025-11-25)

Thanks for this report, filed as RH-90711 and kept confidential.

I’m working on a fix for this right now and should have something working by the next WIP. The images in this PDF never imported into any version of Rhino. They look like they are compressed in a format that our PDF reader doesn’t currently know how to read.

RH-90711 is fixed in Rhino WIP

@stevebaer @brian @BrianJ thank you all, latest wip solved the issue. Faster than v8!!!

(9.0.25357.12175, 2025-12-23)

However another issue with the pdf file so I don’t think it needs another thread.

Problem is: Text object looks hidden but they aren’t. (in Rendered mode)

Left one WIP, right one V8.

I select 64cm to let you see there is a text :slight_smile:

problematic modes: RENDERED, PEN, MONOCHROME, ARCTIC, RAYTRACED.

Here I share object properties :

Thank you in advance :smiling_face_with_sunglasses:

Hi m -

I’m not seeing that here:

When I import your PDF file, I get the following warnings for missing fonts:
Could not find embedded font “TXOUML+Montserrat-SemiBold”
Could not find embedded font “JIOMCF+Montserrat-Regular”
Could not find embedded font “PRQWIT+Montserrat-Regular”
Could not find embedded font “KHIWZD+Montserrat-Light”
Could not find embedded font “HIQUZJ+Tahoma”
Could not find embedded font “RPZMTP+Montserrat-Medium”

Please run the Rhino SystemInfo command and copy-paste its output here.

  • Hi @wim ,

    I don’t get missing fonts error.
    Here is the list I tried after your massage but those are won’t work.
    I changed all fonts to Arial,
    Reset Rendered mode in setting.
    I also tried todays wip build.

  • If I use opengl, it works again :slight_smile: Direct3D just won’t work.

RH-91349 Display: D3D: Annotations Issue

Note that this issue is not limited to the PDF file. Simply creating text in a new document will behave the same way.

Until this gets fixed, if you need to be able to see the text annotations in those display modes, you could replace a single dimension with a new dimension or replace a section arrow with a new leader. As long as that new object is visible in the viewport, all other annotations will be visible in those display modes.
… or just run in OpenGL mode until fixed.

Text issue is solved in Rhino 9 WIP (9.0.26034.12305. 2026-02-03)

Thank you all :clap:
