Section line width

s1897196NSDQ — Tue, 31 Dec 2024 10:03:05 GMT

I'm creating a drawing in Fusion 360, but I've noticed that I can't change the section line width.

As shown in the screenshot below, other lines have an option to select their width, but the section line only allows changes to the line type, color, and visibility. Also, changing the overall line widths doesn't affect the section line width. By comparing the section line to other lines, I can see that its width is consistently around 0.25mm.

Are there any way to change section line witdh?

In Fusion 360, you can adjust line weights in drawings through the Document Settings (I think). However, the software doesn't provide a direct option to change the line width of section lines specifically. To modify section line widths, you might consider exporting your drawing to a vector editing program like Adobe Illustrator or Inkscape, where you can customise line properties more precisely, and then see if it remains the same once exporting it to Fusion...

Not really something I ever cared much about or where I specialise, mostly though that you couldn't change line width till I asked a few people I know.

Hi,

AFAIK the settings in the Drawings in fusion are based upon the relevant ISO and The United States National CAD

Standard (NCS) and possibly the UK AEC Standard. If it isn't a standard in any of those then I don't think you can

actually create a Custom Standard. You might be able to create a Hybrid of those standards but the idea is that they

are STANDARDS so everyone uses them and understands them.

You may be able to modify the drawings after you have created them in other software to get custom Drawings, but

the intent of Fusion is to be a Tool that uses the Standards wherever possible so that it is easy to change between

the various Standards. Take measurements for instance. The basic distance measurement under the hood of Fusion

is the ISO millimetre mm, but you can switch between mm and inches easily and more importantly ACCURATELY

with a couple of mouse clicks. Even other metric measurements like the metre m, fusion treats as 1000 mm. Also

American Customary Units or Imperial Units like Feet are all measured in mm and then converted.

I have not tried it but there are other tricks in Fusion to convert between various Standards and so there may be a

way to also do it with Drawings, but there is only so much flexibility that can be built in without going overboard.

The number of thread Standards alone is a nightmare.

I think you will be out of luck with Drawing Standards. Fusion uses the most commonly used and agreed upon

Standards to be compatible with other software and to meet Industry expectations.

Hi @Drewpan

Your Back!

Just a question, but Fusion wouldn't convert line width back to standard ISO right, for example with Inkscape if something with a thicker line type was imported to Fusion... Just trying to make sure I haven't given any false hope in my first post.

Hi,

As I understand it, if you created a Hybrid line type from the Fusion like an ISO Centre2 Line but NCS width (which I

could not actually tell you if it is an actual thing), then Fusion could manipulate that line within settings. If you were

to import a file from another package that was completely Custom then Fusion would most likely import it and you

could not change it, or it would convert it to the closest Standard. I doubt that if you saved it in Fusion and tried to

import it into the other software again that the custom line would still exist.

The nearest example I can think of is that some software will create vector graphics and save them to a DXF file

which Fusion natively recognises, but curves turn into complex line segments. I think this type of thing would

probably happen with custom Drawing lines.

My advice is to stick to the Standards.

Cheers

Hey,

Just to reply to the OP. I understand your frustration with the section line width/weight. I often have to do drawings for an industry that expects a thick section line weight. My only work around for this was to:

Export my drawing as an Autodesk DWG
Open in AutoCAD
Create and activate a new layer for your section lines
Select all your hatches
Use the command _hatchgenerateboundary
This will create a boundary line around all your hatches
Set a new line weight to your new layer with the boundary lines

It's a bit convoluted, especially if you you need to update your model/drawing in Fusion and have to reexport.

Wish it was native in Fusion.
