DarkClown Posted June 3 Share Posted June 3 I have two identical curves with the width of 2mm. When I assign a solid brush to the second curve, the line width changes (I assume due to the brush preset). Fair enough. When I change the brush width unit of the newly assigned brush to the original width of 2mm (manually edited in the width field of the brush definition) the new width is not even close to the original 2mm. Any explanation for this?

walt.farrell Posted June 3 Share Posted June 3 You say the brush width is 2mm, but according to the brush editor dialog you've shown it's 7.6 px. What's the DPI of your document? That will determine the conversion between px and mm.

DarkClown Posted June 3 Author Share Posted June 3 I entered 2mm at the edit field - it automatically converts it back to pt (that's why you don't see the 2mm in the edit any more) - this should all be based on the same dpi the document uses. 2mm remains 2mm (of course different pt or px depending on the dpi). So I don't care what the resulting pt value is - I entered 2mm and this should be the same width as 2mm of the curve above ... Maybe there's some error in my thinking.

Any explanation for this? You are trying to change the width in the wrong place. Use the stroke panel to change the width of an existing applied brush. Use the Brushes editing panel to change the size of the next, yet to be drawn, stroke.

DarkClown Posted June 3 Author Share Posted June 3 Hmm, in that case: why does the existing path width change, if I change the width in the brushes editing panel?

Oufti Posted June 3 Share Posted June 3 30 minutes ago, DarkClown said: this does not change my arguments Quite a bit… — Points are a physical length unit (as are inches or mm): 1 pt = 1/72 inch. — Pixels are logical elements without any physical dimension. When you define the resolution for your document (x "dpi", wrongly used for pixels per inch), you establish the link between both. As brushes are pixel tools (not vectorial!), their width will always be in pixels, even if Aff can compute it for you, but the stroke width can be in mm, or points or inches. This is where you will change [or check] the size if mm are what you need to control. [P.S.

DarkClown Posted June 3 Author Share Posted June 3 I'm aware that one unit is device dependent - the other one isn't ... My argument: As long as I enter all measurements in mm it does not matter what the resulting pt or px value is. AD does the calculation depending on the dpi - so the resulting value in px may vary - but I don't care, since 2mm width of the first curve need to be identical to 2mm of the second curve! But it isn't. What you see in the screenshot (edit field of the brush editor) is the resulting value AD calculated (depending on the dpi) - but this value is not relevant.

A severe "beep" could indicate the change was inefficient). If I change the pixels value in this brush editor, the width (in mm) in the Stroke panel varies, as do the curve on screen. Hence, if you want a width defined as 2 mm, you'll have to modify the stroke panel, ou check it in parallel if you use the Brush editor.

DarkClown Posted June 3 Author Share Posted June 3 No, there is no error showing up. Maybe I was unprecise in what I was doing. In the edit field of the brush editor I entered "2mm" - not any pixel value. And this converted into the according px value.

thomaso Posted June 3 Share Posted June 3 Was the object in question scaled? Although you didn't mention the Appearance panel, a scaled stroke with active "Scale with Object" option may display different values in the Appearance panel versus the Context toolbar / the Stroke panel. Then deselecting the Scale checkbox can directly lead to a different value in the Appearance panel. stroke width.m4v Quote macOS 10.14.6 | MacBookPro Retina 15" | Eizo 27" | Affinity V1 Link to comment Share on other sites More sharing options...

DarkClown Posted June 3 Author Share Posted June 3 Just to clarify even more ... I can type in "10mm" in the edit field and the brush width increases significantly. So mm to px conversion works.

walt.farrell Posted June 4 Share Posted June 4 According to the Stroke panel, the upper (wider) curve in your screenshots is 5.7 pt, Timo. And the lower (narrower) curve is 1.8 pt. If I turn off the Setting to Show Lines in Points, then I see mm measurements in the Stroke panel. And at that point I can see that the wider stroke is 2mm (as you said) but the narrower one is only .6mm: That seems to match what we see in the design.

DarkClown Posted June 4 Author Share Posted June 4 @walt.farrell that true! But I entered 2mm for the Brush in the brush editor (and the line width adapts to the entries as you can see in the video). So the linewidth should also be converted to the 5.7pt. Could be a conversion bug.

walt.farrell Posted June 4 Share Posted June 4 As far as I can see, if you want to change the size of an existing vector stroke, you must select it with the Move Tool active, and adjust the size in the Stroke panel. Adjusting the size of the Brush does not change the size of existing strokes, for me (only tested on Windows).

DarkClown Posted June 4 Author Share Posted June 4 You can see in the Video that I change the size to 10mm and the vector behaves accordingly, but not in the expected dimension... somewhere must be a bug.

walt.farrell Posted June 4 Share Posted June 4 But my system does not work that way. And you did not show the complete application window, so I can't be sure exactly what you're doing. Thinking some more: Actually, I think I have figured out what you're doing. You are actually editing a Brush, but you're doing it while you have the Move Tool selected, not the Brush Tool. Just as a point of caution: that actually changes the brush in a destructive manner, so if you're going to do that you should make a copy of it first. I cannot comment yet on your assertion that there's a conversion issue, but now that (I think) I've figured out what you're doing I can play with it some more.
