曲线展开会缩小 Curve expansion will shrink

曲线在展开时会自动缩小，头疼

Curve expansion will shrink

AND

移动对象时，按住shfit键可以让对象在直线或45°角方向运动，一些时候，按住shfit键是无效的。试了一下，按十次大约会出现1-3次无效。

When moving an object, hold down the shfit key to have the object in a straight line or 45 ° Angular motion, sometimes holding down the shfit key is not valid. i Try it, pressing ten times will appear about 1-3 times invalid.

There is something odd with your compound path and its dynamic stroke - maybe it was a brush in first place.

I "autotraced" the lines - assigned a dynamic stroke and "Expand Stroke" (blue) now works as expected (Yellow):

 

To get a "normal" stroke back I deleted the "dynamic" property from the stroke - export as SVG and import again - now you can assign new dynamic stroke. This behaviour seems a bug to me.

你的复合路径和它的动态笔画奇特——也许它首先是一个画笔。

我“自动追踪”了瞄准 - 分配了一个动态笔画和“扩展笔画”（蓝色）现在按预期工作（黄色）：

 

为了恢复“正常”的笔画，我从笔画中删除了“动态”属性 - 导出为 SVG 并导入 - 现在您可以解决重态行为的重新动态笔画。这种对我来说似乎是一个错误。

所以，我有什么办法可以再次出现这种情况吗？因为如果是大型插图，会出很多额外的工作量。So, is there any way I can avoid this situation next time? Because if it is a large illustration, there will be a lot of extra work.

Do you really need the Pressure on the stroke? If you simply reset the pressure, Expand Stroke works fine.

[PixelPest]

As shown in my example it will work with pressure enabled: You need to download my "test4U" file to check that the"pressure" property doesn´t work at all on his compound path. So disabling pressure isn´t part of the solution unfortunately - though expanding stroke works then. I´m more curious about why "pressure" don´t work in first place on this compound path…

我仍在想，为什么笔画不接受压力动态属性。

[Dan C]

I can confirm this is a known bug within Affinity when expanding strokes with a pressure curve enabled, therefore I will 'bump' the report with your post now.

As Joachim has mentioned, should you be able to remove this pressure profile, the stroke should expand/export as expected

[PixelPest]

@Dan C this seems to be just half of the story. While deleting the dynamic property solves the expand path issue - this path isn´t longer accepting dynamics at all anymore. This seem odd to me.

And dynamics in conjunction with a basic brushes can very well be expanded on a compound path.

[Dan C]

I agree, it certainly seems odd - unfortunately I'm not sure of the cause for this, though I have logged the file with our developers so hopefully they'll be able to find the cause of the deeper issue here!

Thank you.

我同意，这当然看起来很奇怪 - 不幸的是，我不确定这是什么原因，尽管我已经与我们的开发人员一起记录了该文件，所以希望他们能够在这里找到更深层次问题的原因！

@丹C 这似乎只是故事的一半。删除动态属性解决了扩展路径问题 - 此路径不再接受动态。这对我来说似乎很奇怪。

与基本画笔结合的动态可以在复合路径上很好地扩展。

不仅仅是笔画压力会导致扩展笔画出错，圆角也会导致出错，在笔画末端出现分叉，这种情况同时出现在轮廓工具和画笔中。奇怪的是，同一条线，朝下时扩展笔画显示正常，朝上时就会出现bug

Not only does the pressure of the strokes cause errors in expanding the strokes, but rounded corners can also cause errors, with bifurcations at the end of the strokes, which occurs in both the contour tool and the brush. The strange thing is that when the same line is facing downwards, the extended strokes are displayed normally, but when facing upwards, there will be bugs.

Many thanks for providing this document, I will have this logged with our developers now also

非常感谢您提供此文档，我现在也将与我们的开发人员一起记录

ask a question, if the following four functions are in the development plan, I believe the team will definitely consider these functions. When using these functions, I still have to open the illustrator software to operate.

1. Vertical typesetting of Chinese characters should be a very hard-core demand for the entire Asian region.

2. Extendable line, because vector brush is a common tool, but only the state of no brush can be extended to flat editing, which is more troublesome.

3. Shape generation function. Only one vector design can deal with the increase or decrease of the intersecting part, which is much more efficient than the segmentation tool.

4. Envelope. Almost a large number of abstract geometric background manipulation tools are such tools. I personally use in-depth affinity. In fact, I don't want affinity designer to become complicated. maybe, pixel power and filters are not important, but the ability to handle vector graphics can be considered to enhance some efficiency functions like illustrator.

As you've mentioned, this is highly requested and our developers understand the importance of this feature. We certainly do hope to implement this in the future, however we have no timescale currently, my apologies!

My apologies, I'm not 100% certain what you mean by this - could you please try expanding on this for me?

We use Boolean Operations in the Affinity apps instead of having a Shape Builder - I understand that this is another highly requested feature for the Affinity apps, however I'm not certain if we have any plans for this currently, but we never say never

Please see the answer to 1., as the same is applicable here.

I hope this clears things up!

正如您所提到的，这是强烈要求的，我们的开发人员了解此功能的重要性。我们当然希望在未来实施这个，但是我们目前没有时间表，我很抱歉！

抱歉，我不能 100% 确定您的意思 - 您可以尝试为我扩展一下吗？

我们在 Affinity 应用程序中使用布尔运算而不是形状生成器 - 我知道这是 Affinity 应用程序的另一个强烈要求的功能，但是我不确定我们目前是否有任何计划，但我们从不说永远

请参阅 1. 的答案，因为这里同样适用。

我希望这能解决问题！

2.let me explain the meaning of 2.              The current brush function is that you can expand ordinary lines into graphics, but if you use a brush, this line cannot be expanded. When I need to use a brush, but I want to turn it into a vector graphic, I can only go to Illustrator to expand the line into a surface, and then copy it back. So I was wondering whether it is possible to support the expansion of lines with brushes, or to introduce a brush that can be expanded. The pressure curve of the line can indeed partially replace the brush, but it is difficult to achieve the effect of changing the thickness and texture of the brush.

 

[Dan C]

Support for this in Affinity would require a Vector Trace feature, to convert a pixel stroke to a vector object - this is highly requested here on the forums and is something our devs hope to implement in the future

[Affinity Info Bot]

The issue "Strokes with a pressure profile are expanded with wrong width (affecting SVG, PDF, EPS exports)" (REF: AF-727) has been fixed by the developers in internal build "2.5.0.2463".
This fix should soon be available as a customer beta and is planned for inclusion in the next customer release.
Customer beta builds are announced here and you can participate by following these instructions.
If you still experience this problem once you are using that build version (or later) please reply to this thread including @Affinity Info Bot to notify us.
