It's impossible to quickly create customized guide lines just by inputing the number and selecting the unit.

There are some extensions that provide such function, however, after updating to the latest version of Inkscape, the extensions no longer works.

This should be a basic function.

Please review this topic and add any other relevant info here.

poor service

Click-drag from the ruler to create a guide. Double-click the guide to open a dialog and enter numerical coordinates and units. No extension required. This is a "basic function".

@frankleng:  This forum is where Inkscape users help other users voluntarily.  Nobody here is at your service.

@frankleng, Have you tried reading the manual section on guides?

@Paddy_CAD beat it.

@TylerDurden guide line creator provide no value and unit input function.  （extensions-render-guides creator)

From the built in extension:

@Polygon Thank you very much.

I downloaded this extension before. It might be an older version which can not work well under ink 1.1.1

I just download the latest from https://gitlab.com/Moini/inkscape-guide-tools

It works without errors.

Thanks.

@frankleng, I'm tempted to launch a salvo of expletives. Instead I'll take the high road and refer you to https://inkscape.org/community/coc/
