Drawing "resolution" problems

[Anonymous]

Hi,

The resolution of my drawing seems very low, what is round in my model is showing as octagons or similar (see picture)? Why is this and how do I change it?

Hello monomental,

Your jagged circles are a strange problem. I couldn't reproduce them.  I created a sketch with very small circles and extruded it. The resulted holes are absolutely round, in any zoom level.

As I can see, you are showing a drawing. I guess this drawing does not correspond to a 3D component created by Fusion, but to a solid created by another program and imported to Fusion or to a imported drawing. If this is the case, the problem is probably related to the original file or to the import process.

In any way, please give me more details on the steps you followed to get the drawing. 

Cheers,

Luiz

I have seen this before when patterning a bunch of holes like this and my model was created in Fusion. I think the reason it is displayed like that has to do with performance.

I could be wrong though.

The original drawing was made from a step file. But I tried with a new model extruded a circle with 1mm in diameter and this is my drawing based on this.

Still jagged?? I am on a Macbook Pro i7, late 2015 with 16GB rams. Doubt it is performance related...

I have a very highend system also, but Fusion converts arcs into faceted lines for the display. I just checked on 4 different models and all of them show what your seeing when zoomed in.

I'm not saying I like it or anything but every drawing I have done exhibits this behavior. When I said it is a performance thing I meant for Fusion not your system. I would like to see this resolved also because it makes drawings look bad.

Hello @Anonymous and Phil,

I've produced a new test drawing and now I can notice the start of "jaggedness". It is not as bad as @Anonymous's, but it is there. I agree with Phil it should be an undesirable Fusion feature.

However, I cannot understand how the original @Anonymous's drawing could have such nasty fringe lines inside the circles.

Cheers,

Luiz

Looking at the attached images this looks like the same kind of effect you would see in AutoCAD with a low VIEWRES setting.  VIEWRES controls the appearance of circles and arcs and has a range of 1-20000.  This setting is not exposed in Fusion Drawings, but I checked an output a DWG and and VIEWRES is 1000.  Increasing VIEWRES can increase the time it takes to regenerate the drawing, so (as mentioned above) there is a possible performance consideration here.

I've seen some cases where after extreme zooms in/out this effect can look exaggerated but typically something that forces a regen (like Fit) corrects the issue.  The visual display should not affect the accuracy of the actual drawing, but I will check with the team and verify the expectations here and if there are any system-specific issues that might also contribute to this.

Thanks,
Chris

When I export the file to pdf and open in illustrator, the lines are still jagged (too much for me to use the drawing). The model is a step file I import, but if I import same to CREO and make drawing, everything seems fine...

@cmiller66

The main problem I see here is every drawing I have ever done appears as if Fusion is using poligonal models for the drawings instead of the NURBS data. If you plan to export these drawings to Illustrator or any vector program for that matter, including laser cutters/engravers makes the drawings unusable. The final cut product will have these jagged lines instead of nice smooth flowing curves. Not to mention the fact that the drawings look like they were done on a 30 year old platform instead of a current gen CAD app. I don't mean to sound harsh but this is the reaction I get anytime I send drawings made in Fusion to my clients not to mention the fact that they can't be used for cutting a final product.

Just my 2 cents.

Hi Phil,

No worries and thanks for the feedback.  I added this issue to our backlog (and bumped it up) and we will review with the team. One thing I can say with certainty, when issues like this come up we're not ignoring them, but with other work in progress (like getting multi-sheet support completed) there's always some prioritization that has to happen.  We're definitely not "done", and we'll keep adding new functionality and improving what's already in there.

If you have some other examples of areas that could use improvement, please feel free to send me (christopher.miller@autodesk.com) a screen capture, pdf or Fusion archive (f3z) of the drawing and design and let me know what the issue is. Sometimes with heads down focus on getting a specific feature done, a reminder of what's left to do in other areas doesn't hurt.

Thanks,
Chris

Please fix this.

I want to take screen shot of drawing to send to printer but holes are very jagged indeed.

Hi Mrs. AliceAnnHurd,

Print Screen function on most OSs delivers an agnostic output in a bitmap format. It’s resolution depend upon a monitor setup. As a result the printout generated will be reflection of this, showing a jagged image.
This is probably? a common knowledge so there is nothing to be fixed ... on F360 side.

What steps do I take to get the best quality print from a drawing?
When I select FILE,PRINT the quality is bad so that is why I was taking a screen shot of the drawing for it produced a better quality print but still quite un acceptable. At least the print was centered when I took a screen shot of it wear as file print cuts off the right side of print so right line and arrow is not visable.
Circles are better when I file, print but all other lines have wavy ghosts lines added to them.

are you talking about printing our model sketches, or sheets from the drawing workspace?

[MichaelT_123]

Hi Mrs. AliceAnnHurd,

As to clarify my previous post, it is important to understand that PrintScreen function is a part of GDI (Graphic Device Interface) layer positioned just before Graphic Driver and after the application (F360). Therefore GDI functions are detached from applications. The image output is generated on OS level by directly spooling out a screen memory buffer (and thus not involving applications).

As far as I know commercially available F360 does not offer more sophisticated printout related functions, although they could be implemented. However, who would put a cart before a horse (aka commercial software company)? So as such solution is/might be viable your options are currently limited.

What I would recommend in your current workflow?

Find a computer platform with a high resolution monitor (4K,5K,8K), play with anti-alias setting in a graphic driver and check printout results.

Another alternative is to go paper-less.

F360 is good in this area!

8k laptop would cost a bundle I bet. Looks like paperless may be the way to go. I sure do like high quality paper blue prints though.

when you save your drawing out as a pdf, and then print the PDF, do you still have quality issues? (don't forget the recent updates that allows some adjustment to line weights)

Hi @Anonymous, 

Sorry to hear your having problems with drawings. After reading through all the posts, I'm curious about your printed outputs; those created using File > Print. You mentioned they were bad and this is why you've resorted to screen shots.

Are you able to share your printed results as a photo? I've worked through quite a few print and pdf output issues with users on the forums, this being the latest https://forums.autodesk.com/t5/fusion-360-support/cannot-print-exact-scale/td-p/9487369 so I'd like to see what you're getting. If you could also share some details about your setup that would also be helpful. For example, what sheet size are you using in Fusion, what scale are you printing (1:1, 1:10, 2:1, ...), what kind of printer are you printing too, are you using Mac or Windows.

And as @laughingcreek suggested, have you tried outputting to PDF and using Acrobat to print?
