Offset Path Misbehaving

Jonmurgie — Thu, 12 Jan 2023 16:45:21 GMT

Afternoon all, am struggling to get an imported SVG to behave on one of the offset paths. I "believe" it might be due to an unclosed point but try as I might I can neither find it nor fix/unfix/constrain anything that seems to make this path work when it's anything other than a 1mm offset (I need it to be 1.8mm).

Below is a screen recording showing the behaviour, works correctly when the offset is 1mm but move it to 1.8mm (or anything above 1.0mm) and the path is there but clearly not complete and functioning as I'm expecting it to:

To give some context this is the overall design and the part I'm having issues with is the centre of the "a"

Any advice much appreciated, spent far too long on this already!

You'll probably be right.

Please share the file.

Can you also Post the .SVG?...It maybe easier to tidy up the source in say Illustrator or CorelDraw.

Hi,

1. take a look at white dots

2. try to use divide and conquer technique

By the way, it is important to know that the offset of special contours almost regularly breaks.

If you delete this spline then redraw and add a smooth or tangent constraint at both ends you can then offset by 1.8mm and still have closed profiles. I used a Fit Point Spline just picking the two points then added the constraints. Note, I deleted your offset then recreated the offset after adding the new spline.

Thank you! Went with this option as the quickest fix that saved the piece given I've already printed all other elements I couldn't go too far back to start messing about.

Realise that ultimately on this one I should have paid more attention at the Illustrator stage before saving the file to an SVG. Been a few years since I've used Illustrator with any confidence so bit of a learning curve!

Many thanks for the other suggestions too, particularly @g-andresen for your input 🙂
