combine tool is not working

[norgmonster]

Hi,

I've spent the last 3 hours trying to combine a body with a sheet-metal body. I've done this a 1000 time on similar projects with it working fine.

Now, when I try it says:

Error: There was a problem combining geometry together.
If attempting a Join/Cut/Intersect, try to ensure that the bodies have a clear overlap (problems can occur where faces and edges are nearly coincident).
Failed to Boolean bodies together

I also get error messages like:

Error: inconsistent edge-face relationships

Both sides to join are flat and the same size so I don't know why it would be having an issue. I'm also not a stranger to fusion so have tried a number of things.

Can someone please help?

Thanks,

Jonny

Hi,

Thanks for your help on this issue.

I don't know if this thread is still active but I'm having issues with fusion struggling to do the most basic things on what are relatively simple models (not the one I showed you before).

I use a mac and just selecting a face or trying to move a body often ends up with the spinning disc for 10 - 20 seconds. This is sometimes followed by it crashing altogether.

My mac specks are quite high so I don't know what the issue could be:

Mac (Retina 5K, 27-inch, 2017)
Processor 4.2 GHz Intel Core i7
Memory 40 GB 2400 MHz DDR4
Graphics Card Radeon Pro 580 8 GB

Please give me some suggestions.

Thanks.

The previous model was not created using efficient techniques.

Can you File>Export your new *.f3d file to your local drive and then Attach it here to a Reply?

[norgmonster]

Attached is the project file.

It's not just with this one. I get the same slow down issues almost all the time.

[TheCADWhisperer]

I would expect to experience issues with this modeling technique.

Hi,

What do you mean by that?

Why would it be an issue?

[TheCADWhisperer]

I will create example later today, but why did you create more than 3 dozen bodies, only to remove them?  Is that the way you would logically do it in the real world?

Move Bodies or Remove Bodies should only be used sparingly.

Resolve any yellow or red highlighted issues as they occur.

[norgmonster]

Why should moving bodies be an issue?

One has to be able to work on a body and then move said body into place (aline it with others) as the design progresses.

As for making 3 dozen bodies, I made one, then duplicated it, then combined it into one. I'm not sure what you mean when you say i removed them.

If I removed anything, it would be because they were not quite right and I started again.

Are you referring to "body93" and "body94"?

This is a representation of a brick wall. In "real life" one would need to use individual brick.

I don't know how to resolve yellow or red highlighted issues. Let me look it up on my end.

Thanks for the help so fare.

1. But unnecessary work, why not do it in Design Intent location from the start?  Get lazy, avoid extra work.

2.  See image.

3. In the real world would you create a brick wall and then cut openings into the wall?  Maybe, but probably a more efficient use of your bricks, your physical effort and your time to not lay bricks and then remove them for openings in your wall.

For point 1)

if I have to adjust the size of a body or extrude a face then re-aligning it afterwards is unavoidable.

For point 2)

Looking back at it, the 3 dozen bodies made were as a result of splitting another body. The smaller "off-cuts" were not needed and so removed/deleted.

Out of interest, what is the difference between "remove" and "delete" as options when I right-click? Should I be using one over the other to get rid of unwanted bodies?

For point 3)

If you have an existing wall and would like to add a window then you cut a hole in it, don't you? 🙂 In Fusion, It's easier for me to make a wall and then cut a hole for a window after. Discussing real-world construction processes in a digital space seems redundant. The main point is, does doing it this way affect the speed that my Fusion is running.

The problem I originally approached you with is why am I getting so much "slow down" or "lag" or "crashing"?

Please let me know your thoughts.

Thanks for your help so fare.

1. Why are you telling me that I am wrong? Extra work is avoidable.

2. Why do work that is not needed?

3. Why am I asking you redundant and apparently irrelevant questions?  Why would I do that?

My thoughts?  You apparently don't trust my experience, so I will pass this on this effort to someone who you do trust.

[norgmonster]

I do trust and appreciate your thoughts. I think I'm not expressing myself very well.

[TheCADWhisperer]

It will be some time now till I can get back to this one as others have asked questions that I am addressing.

[norgmonster]

1.) I'm not saying your wrong. I just have my own way of working. Why should moving bodies around effect the running and or slowdown of Fusion?

2.) If I split a body, I will have parts I need and parts I don't need so I remove what I don't need.

3.) How one makes a brick wall in the real world is different from how one can make it in Fusion. That's all I'm saying. Based on your last response to this point it sounded like my modelling proses was the issue.

I just want to know if the way I am working is making Fusion stall, crash or slow down. Is it a hardware issue. How might I fix the problem?

I am grateful for your help. 🙂

Start a new part file.

Create a sketch as shown below  (make the three lines Equal and Colinear).

File>Export and then Attach then new *.f3d file here for next step.

[norgmonster]

Hi,

Thanks for replying.

Sorry but I'm not sure what it is you are asking me to do hear.

Why do I need to redo what I already have?

My question was "why is Fusion running so slow"?

I use a mac.

It slows down when I try to do the most basic of things like draw a line, extrude or even save. I get the spinning ball that lasts 10 - 20 seconds and sometimes it just crashes.

I have attached the file for you as you asked.

1. Because everything you did was done in an inefficient technique that will surely cause issues.

In the new file that you Attached - you repeated this incorrect technique.

Where is the Origin Center Point (0)?

Are there any blue lines in your sketch?

Are there any white dots in your sketch?

Why do the dimensions on this sketch not match your original model?  Was you original model incorrect?

Why are the three lines I indicated to have Equal (=) constraints missing this constraint as directed?

Why are the three lines I indicated to have Colinear constraints missing this constraint as directed?

I think maybe I was going to fast.

Start a new part file and this time sketch only a rectangle as shown.

Note the position of the Origin (0).

2. Are you saying that the second file that  you attached here is slow on you machine?

If this second file is slow - we have a real problem here and change in technique is not going to solve the issue.

[norgmonster]

The new project I sent you is fine (not slowing down). It's just generally like I said before.

I don't know what could be missing from the sketch i sent you before. I just drew it out as you showed me in the last email.

Attached is the 20 x 60.75 file.

It would help to know what you are talking me though as I don't know what was wrong with my original. What was "inefficient" about it?

Thanks 😉

How did you miss the Origin? Again? Didn't you see my red arrow in image that I attached? Did you choose to ignore the red arrow?

[norgmonster]

Ok.

I'm starting to understand a bit more now.

I have to be honest and say, although I have been using Fusion 360 for a number of years now, I've almost never used any of the "constraint" tools. I'm self-taught so may have some bad habits ;-).

In the past, I've gotten by with just the "create" and "modify" options to make my sketches.

I'm also not familiar with a lot of the terminology you used in the video.

The reason there are so many repeated lines over each other is that I lay shapes over shapes, then use the trim tool to remove what i "DON'T NEED".

If you're saying it's the sketches that are slowing everything down then I can certainly take at some tutorials online to make better use of all the tools.

Thank you for pointing them out to me.

Do you have any suggestions on specific tutorials that can help (beginners guide to constraints tools in Fusion 360)?

Thanks,
