I'm bringing this post back to the surface because even after 2 years, we are still dealing with having to single out all multiple quantity panels in order to output to the machine and this is very tedious and time consuming.

Zitat von Markus Brunn

You can not transfer beams that have the same sorting number but are different in shape and processes to the same machine file.

My question is -why are panels with different shapes and processes receiving the same sorting number? Shouldn't they receive different sorting numbers if they have different shapes and processes and thus solve the machine output problem?

When i create single sheathing panel drawings, I set the fixed scale to 1:48, but it creates drawings at a scale of 1:72. Why aren't the drawings created at the scale i set?

After optimizing the 4-5/8" thick SIP walls I noticed that panel (#59) (qty:1) was optimized at a qty of (14).
Also, the optimization is missing panels:
68-qty:6
69-qty:6
The project was originally created in v9.04, and now being used in v10.02.

No not realy but I do not know your whole situation.

Here is the situation:
#1. The goal is to have the best material yield.
#2. The size of the material is 8'x8'/14'/16'/18'/20'/24'.
#3. The amount of material available is whatever it take to achieve #1.
#4. Material "drop" or "waste" is thrown away, we typically do not use it for another job.

Zitat von Joachim Neumann

If the program would try to use all lengths the optimization would need much more time.

#5. We can let the optimization run overnight in needed.

Please let me know if you have any more questions.

Also, Joachim you have an open invitation to come to Holland Michigan to see for yourself our situation.

Take a look at the attached file and create a material list to see if any list created "combines" with an already created list in project data.

When I create a material list in this project, it wants to create 012 list, but a list has already been created here.

Zitat von Joachim Neumann

In such a case as you describe it above you have to help for a good optimization. You could optimize some panels with the raw panels you feel best and then the other panels with other raw panels.)

Do you have any more suggestions to help get the best yield out of our situation?

Your english is fine and understand what you're saying, but what you are saying is a huge issue for us.
"The program does not use all raw panels which are available"
-Why not? Isn't that the whole point of having optimization?

"It is programmed to use as less material as possible"
Then this statement is not true because it's not using all the material available.

See the attached file. When I optimize I make the following raw panels lengths available: 8'/14'/16'/18'/20'/24'
See nestings: 22/24/25/34-46/49-50/56-59. These are all nestings that used a 14' raw panel. The used length on these nestings are under 10'.
Why weren't the panels doubled up to use the available 20' raw panels?

Thanks. Staying on this same topic I want to say that there's another issue with the way we optimize and the way the programming is written for optimization. It has to do with the reason you said waste can be used for the next optimization and that's why such a high yield is shown for an 8x8 panel being nested in an 8x16 and that's exacty the problem.

For example:
If sufficient utilization is set to 95% and I optimize (4) 8x8 panels and my available material is 8x16, instead of optimizing (2) 8x8 panels in an 8x16 raw panels, it will only optimize (1) panel in an 8x16 because it thinks its ok because the sufficient utilization is 100%, when i fact it's not ok. It's forcing me to use more material than i need. Now, this situation doesn't happen every time, but it does happen and it is a problem since we don't use waste like you said the optimization is programmed to do.

I think "max operation time" is also a factor because i don't know how much time to allow so that i get the best yield.

Can you add the option to show utilization percetage of panel being used as explained in my first post? An 8x8 panel in an 8x16 raw panel should be 50% utilization.

It's done it version 9, and still in 10.02.

In our case it is waste. We don't have the room to keep the "drops" off panels to be reused on another job that might be a month or more away. So we laminate panels to the size - of best optimization in 2' increments from 8' to 24'. So typically the waste is less than 2' (off the end of the panel).

Is this an option that could be added?

The “store for list” option does not go to the next available number in the database, this is problematic because if not careful the list will be “mixed” with a list that was previously created. Instead, the database has to be opened to see what the next available number is and that number need to be manually input. The material list creation (in dcam)works because it automatically uses the next available number in the database.

After completing an optimization sufficient utilization is listed as a percent. This percent only applies if the raw panel is shortened to the used length. Shouldn’t this percent apply to the entire panel if the selection to “shorten raw panel to used length” is set to “No”? For example, if the optimization nests an 8x8 panel in an 8 x16 raw panel, the utilization percent should be 50%, not 100%.

Why does the optimization run longer than the max allowed optimization time?

I realise this is an older post but i have a very large job right now where i sort according to position and there are 87 different panels - most of which are multiples of the same. When i try to output to machine I get the error message:
"Among the selected group of objects are different items with identical sorting numbers"
So i sort according to wall like Markus had stated to do above, and now instead of having 87 parts, i have 237. This just made a lot more work, as i usually have to edit each print and manually nest these as well. Are there any other options so i can keep my 87 parts?

It would be nice if chimneys could be edited, instead of having to delete the chimney and put a new one in.

ok. What about the objects (sips)?

I have a house drawn - walls only, that consists of wall volume and it is panelized with SIPS. I need to mirror this house - walls and panels, is this possible, and if so how do i do this?

I have ran into this as well. For whatever reason it's not letting you output items with quantities over 1. What I do is activate only 1 item of the multiply quantities(so if you have an item that has a quantaty of 6 then you only activate 1 of those 6) then output these items and change the quantaties back to the correct amount after you have output them. This can be a tedious ordeal if you have many multiples and maybe there is another way around it...but i haven't figured that out.
