Corner Join Not Working

[dawningtruth]

I have a complex star which was generated in CorelDraw. It is too complex to reproduce in Affinity.

I have therefore imported it via svg, wmf, pdf, and emf.

In each case it imports, but does not reproduce the corners correctly.

Here is how it looks in CorelDraw:

 

And here is how it looks in Affinity:

 

I have tried changing the corner join modes to mitre join, but then I get:

 

Any suggestions on how I get the correct corners?

Thx

There is a mitre setting that you can increase but from the last image it looks like those curves/paths aren’t joined.

[dawningtruth]

Thx, I have tried that:

To my knowledge the nodes are joined:

And here are the join settings. I have tried every possible combination. It does work for rounded corners, but not sharp corners:

Any other thoughts or suggestions?

Playing around a bit with the problem and I had to get the Mitre up to 12 in order to get the pointed corners.

[dawningtruth]

Ok, I managed to come right.

I did a precision export from Corel Draw in svg.

Problem Resolvd.

All of your lines were closed shapes - so no corner will join. A mitre limit of 3 should be sufficient.

[dawningtruth]

Thx, it was obviously an export issue.

Feature request: Better support for importing Corel Draw files.

Just out of interest, why do you say that the shape is too complex to produce in the Affinity applications?
In other words, what is it about the shape that makes you think that it can’t be created in something like Designer?

[dawningtruth]

Perhaps it is my ignorance of how to use the tool. Corel Draw has a special star tool which allows you to create that type of star. After quite a lot of looking around, could not find the necessarily settings.

[GarryP]

If you can show us the whole star – and describe the important parts – someone may be able to show you how to create it in Designer (if it is possible).

[kaffeeundsalz]

Well, if it's just what can be seen in @PixelPests GIF, one way to do it would be something like this (edit: granted, a dedicated tool is probably still faster):

[G13RL]

Something approaching from the left curve, repeated 36 times in a circle.
One difference, the central nodes are located more inward than on the original.

[dawningtruth]

Wow! Thx, yes, that is one way to do it.

[GarryP]

If you don’t have any specific requirements for the number of points then you can use a four-pointed star to get a similar result – see attached video where I also make the star a Symbol so the full shape can be easily altered into some interesting shapes.
The best method probably depends on your exact requirements.

[PixelPest]

Unfortunately, none of these methods apply to the 33 point star.

I can easily draw the 33 lines at 10,90° degree - but connecting the end-points won´t work in AD afaik.

[G13RL]

If the shape should remain a shape, why not make a compound or "Add" after "Expand Stroke" of all the lines?

Because you can´t adjust the mitre angle?

[G13RL]

If you set the miter on the curve at the start it is not a problem.

[PixelPest]

You can´t get a 33 pointy star by this method as the OP want in his linked file (which he deleted in the meantime).

[G13RL]

Without seeing exactly what is required it is difficult to try to reproduce it.
For 33 spikes with my method, I don't see what the problem is!

[PixelPest]

This kind of star just needs 33 points:

If you don´t see the difference I can´t help any further.

 

[G13RL]

Thanks for the explanation.

[PixelPest]

You´re welcome - sorry for being the pest. 🤪

If the rotations are accurate (use 360/33 (or 10.90909090909091 🤕)), just select everything and, with node tool active, hit Join Curves once and Divide once.
