Boolean operation curvature / curve tolerance

Boolean operations remove curvature in an object.

The middle is similar to the result I would like except extra nodes were created top and bottom, this was done using the new scissor tool that is awesome by the way. The top is what I start off with but when I run weld all or boolean union of two the result is the bottom. It also does this with other curves.

This was on the edge of a letter.

I did use this function this morning to create a bar with smooth rounded edges, went to do it again after the update and this happened. This may be a simple setting but I am struggling to find it.

I’m not completely sure but I would try to make adjustments here:

Thank you for helping. The menu changed a bit in 1.7 but it is the same setting.

I don’t understand the setting fully but I think it comes down to, for me with 1.7 I was doing something in Lightburn that I usually do in Inkscape. Which is modify smaller objects and with a project needing to get done I didn’t notice. I’ll have to keep playing with it but I think that was it.

What I think I’ve found out today is that in Lightburn there is a correlation between size of object and nodes created when modifying the object. I’m in the middle of trying to get orders out the door so I will have to come back to this, it’s just funny that this update added so many cool things I didn’t switch between the two and just stayed in Lightburn for the first time and I created an issue for myself.

Thank you again.

Neither do I, which is why I said “I’m not completely sure” but I’m aware that it has something to do with the precision of a curved line.

I’ve never worked with Inkscape, I only know it by name, and the little experience I have is limited to Lightburn.

I don’t think so, unless you create a new line, whether curved or straight.

In a tutorial I saw a few days ago, it is possible to create and delete nodes, all of which represent a point that allows you to modify the line.

I am convinced that changing dimensions does not create new nodes, but again, I am not completely sure.

In any case, I am happy to have helped find a solution to the problem.

Again thank you, that setting helped a lot. I’m only responding to give more context and hopefully help someone like me down the road.

Honestly I’m probably doing this all wrong but stumbling through things until I get a decent result is what I have had to do. I am trying to go back and relearn from the start but it can be hard when things still need to get done.

Best way I can describe is with pictures I guess.

Both on left were made in Lightburn both on right made in Inkscape.
The bottom two were made by combining a 1mm circle and 1mm square, the top two were 200mm circles and squares. I use these because of the simplish nature of the humble square and infinigone.

This can become more pronounced with more complex shapes. The reason this is important to me is that if like in the first pictures I get those straight lines in what was a curve and I scale up and forget about them they become very noticeable and things like having a tight fitting inlay can become difficult.

Honestly I have learned so much here in the past day or so, I think I’ll be scouring these pages quite a bit.

Edit- I didn’t think about this until after I posted this but I do have an additional question for any who may see this. Would be useful to change the title since I don’t believe it was the update? It was more that I changed my habits due to the update.
