I have pivot problem. I am setting, a pivot in Maya (for a car wheel) and when I import the fbx of the model in Blender, pivot point is resetting on null.
Any solution about that problem?
Save your wheel inside a new group and position a group's pivot to a desired place. It'd work when you open your file in Blender. Here's MEL equivalent for Maya Script Editor to test group's pivot point:
polySphere -r 2 -sx 20 -sy 20 -ax 0 1 0 ;
doGroup 0 1 1 ;
move -r 0 5 0 group1.scalePivot group1.rotatePivot ;
Also, when exporting from Maya it's better to choose DAE_FBX export file type.

Is it possible to manage the entries created within the IntelliJ History clipboard and that we can consult using command "CMD+Shift+V" ?
Why: This is because I see a lot entries which are polluting the history when text is copied
Example - Paste from history
1 ~/Library
2 ~/Librar
3 ~/Libra
4 ~/Libr
5 ~/Lib
6 ~/Li
7 ~/L
8 ~/
9 ~
....

Disable the Copy to clipboard on selection option at File | Settings | Tools | Terminal:
Entries in the history dialog can be removed using the Del key. You can also use Shift+Arrows or Shift/Ctrl + mouse clicks to select multiple entries before the deletion.
I'm working with PDF files that have hundreds of forms within them. Each form is 2 pages long, so in most files pages 1-2 is the first form, pages 3-4 is the second form, and so on.
However, there are several PDF files where the page order of the forms are reversed. In these cases, page 1 is the second page of the first form and page 2 is the first page of the first form, page 3 is the second page of the second form and page 4 is the first page of the second form, and so on.
I want to reorder the page order in these files so that the pages are in this sequence: (2(1), 2(1)-2, 2(2), 2(2)-1, 2(3), 2(3)-1,...,2n,2n-1), where n= total number of pages/2.
I've been looking for a way to do this using command line tools such as cpdf, pdftk, etc., but to no avail. The files are quite large so I would like to do it by using command line tools.
Any advice will be greatly appreciated!
CIB pdf toolbox of CIB (https://www.cib.de) has a (non free) command line tool version, which supports all possibilities of PDF merging in one run.
Did you try poppler-utils?
i think with the command line tools pdfseparate and pdfunite utilities you can achieve all you want.

Would it matter to you if the order of the forms inside the PDF is changed? For example if instead of
form1-reversed,
form2-reversed,
form3-reversed
your resulting file would look like
form3,
form2,
form1
?
In this case you could just run PDFtk so that it completely reverses all the pages of the original file:
pdftk in.pdf cat r1-1 output reversed.pdf
(Prefixing a page number with the letter r references pages in reverse order. That means r1 is the last page...)
In case you are on an operating system which supports shell scripting (like Bash on Linux or macOS), you can achieve the output of your requested page numbers by something like this (assuming that your n==10):
for i in {1..10}; do
echo -n "$(( 2 * ${i} )) ";
echo -n "$(( 2 * ${i} -1 )) ";
done
This will output 2 1 4 3 6 5 8 7 10 9. Now you could use this PDFtk command for re-ordering the pages as you want:
pdftk in.pdf cat $(for i in {1..10};do echo -n "$((2 * ${i})) ";echo -n "$((2*${i}-1 )) ";done) output out.pdf
I have developed a model in Netlogo and i want to automate the model run.
Basically what i want to do is read the input from either an excel, csv or .txt file and then ask Netlogo to change the inputs in the model accordingly. Run the model for lets say 100 ticks and store the required output from the 100th tick onto either the same file from which the input was read-in or export it onto a different file. Something like this
Trial Input1 Input2 Output
1 10 20
2 20 20
3 10 30
.
.
.
100 20 100
The variables Input 1 and Input 2 are in the interface either as a slider or input button.
Use the Behavior space feature in Netlogo. It's available under the Tool and below is the documentation on the topic.
https://ccl.northwestern.edu/netlogo/docs/behaviorspace.html
I'm doing some optimization using a model whose number of constraints and variables exceeds the cap for the student version of, say, AMPL, so I've found a webpage [http://www.neos-server.org/neos/solvers/milp:Gurobi/AMPL.html] which can solve my type of model.
I've found however that when using a solver where you can provide a commandfile (which I assume is the same as a .run file) the documentation of NEOS server tells that you should see the documentation of the input file. I'm using AMPL input which according to [http://www.neos-guide.org/content/FAQ#ampl_variables] should be able to print the decision variables using a command file with the appearance:
solve;
display _varname, _var;
The problem is that NEOS claim that you cannot add the:
data datafile;
model modelfile;
commands into the .run file, resulting in that the compiler cannot find the variables.
Does anyone know of a way to work around this?
Thanks in advance!
EDIT: If anyone else has this problem (which I believe many people have based on my Internet search). Try to remove any eventual reset; command from the .run file!
You don't need to specify model or data commands in the script file submitted to NEOS. It loads the model and data files automatically, solves the problem, and then executes the script (command file) you provide. For example submitting diet1.mod model diet1.dat data and this trivial command file
display _varname, _var;
produces the output which includes
: _varname _var :=
1 "Buy['Quarter Pounder w/ Cheese']" 0
2 "Buy['McLean Deluxe w/ Cheese']" 0
3 "Buy['Big Mac']" 0
4 "Buy['Filet-O-Fish']" 0
5 "Buy['McGrilled Chicken']" 0
6 "Buy['Fries, small']" 0
7 "Buy['Sausage McMuffin']" 0
8 "Buy['1% Lowfat Milk']" 0
9 "Buy['Orange Juice']" 0
;
As you can see this is the output from the display command.
I'm new to Octave/Matlab and I want to plot a 3D-Graph.
I was able to do so using a predefined formula, like this:
x=1:.1:5;
y=1:.1:5;
[xx,yy] = meshgrid(x,y);
z = sin(xx)+sin(yy);
mesh(x,y,z);
But now the question is how to do the same getting the data from a CSV (for example). I know I can use the function csvread, but the big question is how to format the CSV to contain such data.
An example of doing the same graph above but this time grabbing the data from Excel/CSV would be appreciated. Thanks!
Done! I was finally able to do it!
Here's how I did it:
1) I've created a file in Excel with the X values in the cells A2:A42, and the Y values in the cells B1:AP1 (so you form a rectangle).
2) Then in the cells in the middle I put the formula I want (ie =sin(A$2)+sin($B1))
3) Saved the file as CSV (but separated by spaces!) and manually edited it to look this way (the way QtOctave opens matrix files, in Matlab it might be different). For example (note the extra space before each column):
# Created by Octave 3.2.4, Thu Jan 12 19:32:05 2012 ART <diego#notebook2>
# name: z
# type: matrix
# rows: 3
# columns: 3
1 2 3
4 5 6
7 8 9
(if you're not sure how to do it, do what I did: create a simple matrix and export it to see how the exported file looks like!)
4) Octave has a function under Data -> Load matrix from file, which loads that kind of files. Or actually running this command (varname is the name of the resulting variable):
load("-text", "file-where-the-data-is", "varname")
5) Create the graph (ex is the name of the matrix I've just imported):
x=1:.1:5;
y=1:.1:5;
mesh(x,y,ex)
