can you integrate the Krita line tool?

But I wonder if for architectural design you would not be served better with Illustrator (among the Adobe graphics applications) or even more specialized applications. 

You could try using the Pen Tool set to »Shape« with a Stroke. 

Hi there,

Photoshop handles pen pressure differently to apps like Krita. Which version of Photoshop are you using and on which operating system?

If you are not already using WinTab, turn off Windows Ink and set up the Wintab text file.

1. Create a text file in a text editor such as Notepad.

2. Type in the following lines:

    UseSystemStylus 0

3. Save the file as a plain text file named PSUserConfig.txt in the Photoshop settings folder: [Installation Drive]:\Users\[User Name]\AppData\Roaming\Adobe\Adobe Photoshop 2020 \Adobe Photoshop CC 2020 Settings\

Let us know how it goes.

Thanks,

Akash
