Eraser does not work.

Asked by Jan Novak on 2017-08-29

Hi!

I want to use the eraser in inkscape. I switched on the mode to cut out parts of the objects, but when I use it to erase parts of the object , it erases everything on the trajectory and it draws a black contour of the trajectory!! This is not written in the help and I did not see this property also in the videos about usage of inkscape.

Greetings!

Jan

Hallo Jan,

(sprichst Du Deutsch?)

Can you share a file and tell us which objects you are trying to erase, and also make a screenshot of your eraser settings, so we can see for ourselves what exactly is going on? Or make a short screencast + share the file?

Hallo Maren,

danke sehr fur Deine Antwort. Ich spreche Deutsch. Aber ich kann die
technische Termine mehr in English. Also ich werde es jetzt in English
formulieren.

I created a box folder in my computer and I added there two files.
https://db.tt/S6noRWuyCK One is the printscreen of the setting of
inkscape, the second one is the picture. What I wanted to draw, is a
circle on the left and two intersecting circles on the right. Then I
wanted to erase a small line inside the circle and everything, what is
inside the circle is the result of erasing.

Did You get the files?

Danke sehr. Viele Grusse schickt

Jan

Hi Jan,

dropbox requires me to login to view the files, but I don't want to create an account. Can you make them publicly accessible, please?

No problem with the German, I just figured that your name sounded German, and wanted to make it easier, in case you'd have preferred that :)

Hi Maren,

so the 2 pictures are now publicly accessible on my previous webpage:
johnnewman.mypage.cz; There are 2 files in the section for downloads (
Relativisticky seminar), Screenshot and Figure_1 In the screenshot is
the exact setting, when I use the eraser. The second picture is the
drawing, which I want modify. I want to erase everything inside of the
left circle, but it is not possible with the eraser. It draws some
contour around the trajectory.

Hachmann (marenhachmann) said : #5

Hi Jan,

okay, thank you, I understand.

There are two issues:

1. Your Inkscape version is outdated (this may be intentional, of course). We're at 0.92.2 now (but this doesn't change anything here, just a hint).

2. The eraser erases fills, not strokes. It is working as expected. If you add a fill to the shape and remove the stroke, you will understand better what is happening.

You need to use the node tool to remove paths and nodes that you do not want to have in your drawing.
Switch to node tool, select nodes that you want to delete (you can drag a box around them, or Shift+Click to select multiple nodes), hit Del.

Jan Novak (johnynewman) said : #6

Hi Maren.

Thank You very much for You answer. I was able now to erase all nodes
inside, I put new version of the picture on johnnewman.mypage.cz. .

Please, I have one more question. My intention was to draw a circle. I
used the tool "drawing of lines by hand". I want to make the curve
smoother now, because there are too visible bumpinesses. There could
be some bumpiness, but not too much. Should I use the tool for
working with nodes?

Thank You for an advice.

Greetings sends

Jan

p.s.:
I need to draw some pictures for my work in physics. I think that
Inkscape could be a useful tool.

Yes, definitely, Inkscape is very useful for many types of graphics!

As for drawing a circle, is there a specific reason why you're not using the circle tool? It produces perfect circles right away.

To make a hand-drawn shape less bumpy, you can:

a) use the interactive simplify setting of the tool in versions > 0.92 (need to select already when you start drawing)
b) use the simplify path effect in versions > 0.92 (can be applied later)
c) set a different 'smoothing' level for the tool already when drawing (works also < 0.92)
d) use Path -> Simplify or Ctrl+L to simplify a selected path (works also < 0.92)

(btw. I wasn't able to find the file on the website)

Hachmann (marenhachmann) said : #8

(Inkscape also has the ability to work with LaTeX, if you should need that - via extensions, mostly, but also via direct export)

Jan Novak (johnynewman) said : #9

Dear Maren,

thank You. I will try to do the circles according to You advice.

I finished the work on the picture, which I wanted to create. I put it
on johnnewman.mypage.cz ( I appologize that it did not work
yesterday), the file is called ring. But it was very tedious to create
the text with indices. By the way, my version of Inkscape is 0.91.

I have the following question: there is no problem to create a text,
but when I wanted to add an index, it was a trouble; I did it so that
I moved the small number 0 by alt + arrow to the final position. But
it has the disadvantage that the word Ten is then not symmetric. (I
mean every index must be made by certain number of moves and I had to
count the moves.) I did not know why it was also so difficult to
reduce the letter. I wrote 0 and then I wanted to reduce it, but when
I touched the button on the right, it did not reduce the letter.

I had really trouble with marking the letters. I make a frame around
the letter, but it did not mark a letter. I do not know also why it is
not possible to copy and to paste. (For example, when I copied from
Microsoft Word, it did nothing.)

Finally, how to make the arrow. This arrow, which is in the picture is
composed from 5 lines. But I suppose that it will be definitely
possible to do it directly.

I thought about the possibility that troubles are caused by wrong
installation of the Inkscape. But maybe I only do not know, how to
work with it correctly. (I have Windows 7.)

Thank You very much.

Jan

p.s. : Please, one more thing. How to save the file? When I do it
standardly, it did not save the file. There occured the sign of
Internet Explorer in the folder, and it was not possible to open it.
This file, which I put on the Web was "saved" by exporting.

As for the subscript and the arrow, take a look here:

https://youtu.be/Lnv7aI6nx7U
https://youtu.be/m0iO1fqI5CA

As for saving, please save as 'Inkscape SVG'. Make sure you have permission to write to the directory where you are trying to save.
To 'mark' letters, either use the keyboard, or make sure that the mouse cursor looks like a cursor (like when you type text), not like a pointer or a hand. Use the text tool for this.
For the arrow, you can also take a look into the available Symbol libraries that come with Inkscape (Object -> Symbols). Some of the AIGA arrows might be okay (but probably they are too thick).

For copy-pasting, make sure that you have a text object that you paste the text into. You can only paste text into an existing object.
I.e. click on the canvas with the text tool first.

For diagrams, try to avoid using the pencil tool. Instead use the shape tools (circle, rectangle, stars,...) and the B├ęzier/Pen tool.
