[LDPatternCreator] Known Bugs?
#1
Hello,

as I wrote a few times before, that I am very motivated to fix the last "unknown" bugs in the code of LDPatternCreator (LPC).

The main problem is, that I am not able to reproduce some of the critical errors.

Here is a list of issues which require in my opinion more investigation:

  1. From time to time, LPC "forget" the information of primitives. The geometry is still there (triangles, etc.), but the primitives are gone.
  2. Sometimes, the information of the background image offset and scale is missing.

PS: LPC is compared to LD Part Editor a very small piece of software (25k lines of code vs. 100.000 loc).

Thanks for taking those up!

Here is one case:

"LDPC displays Primitives oriented incorrectly"

The primitives that are used in this design were copied multiple times. After copying somehow I got the impressing that whatever changes I did to the copied primitive were applied on the source-primitive as well. However the source primitive did not change its appearance on the screen.

Now what is in the LPC file: When opening the LPC all primitives look correctly aligned, however if you select them one by one, you see that some are scaled with positive values and some with negative values. The *.DAT Export will then show the primitives according to this orientation which does not match the display of LPC.

Files are attached

I am trying since about a week to reproduce this (I can see what the error did, not where the root cause is). I will not give up... just want to say that I am doing something.

Something that imho qualifies as a bug: if you change post-processing options, they are not saved along with LPC files, this can be annoying if you work again on same file later.

I'll investigate on the background image once I'm back home by the end of April.

This isn't a bug but nonetheless a bit annoying:

* Drawing a curve, it would be useful if you could define the number of vertices also at the beginning and change the number once the end point is set. This most true in those cases where you draw more sections and the number of vertices gets stored in between. This is even more annoying when you finish with say 2 or 3 vertices only and start a new curve - you simlpy lack accuracy.

* It's not possible to select the vertices of the templates say to divide a line. You have to get rid off the template in order to do that.

* It would be nice if you could set the snap via toolbar buttons instead of the a bit cryptic (1/1000 LDU). At least for 1, 10, 100, 1000.

One more I came across:

"When a Vertex is positioned close or on top of a Reference Line, e.g. when using Templates, it cannot be selected and moved"

You can click on the vertex, LDPC will give you the coordinates, however you cannot move it.

Not so much of a bug, rather a question/request:

When I use the templates, I can use a .dat file where the pattern will be applied to.

Now I am generating bent stickers. Can I include the box for the stickers, which consists of quads, into the template file? It looks like it is only reading the first quad.

This is the template:

Code:

Sometimes it crashes, sometimes it generates only the first quad.

Here is a list of issues which require in my opinion more investigation:

  1. Sometimes, the information of the background image offset and scale is missing.

Here we go. Presumably you've loaded an image and have already set some vertices. Now:

* Hide the window with the image preferences "View > Image F5" (as a side note I never understood why it isn't called "View > Image-Preferences F5" since there is also "View-Preferences" and the window itself is named "Background-Image". Asking me I would rename both to "Image-Preferences ").
* With the window hidden save the file.
* Loading the file the X- and Y-Offset are set to 0 while Scale has been set to 1

On the spur of the moment:

* Closing LDPatternCreator and re-launching it I always get it with the grid shown and the color bar hidden. I really want the GUI as I set it. Don't these setting getting saved?

* I wish LDPC had a Txt2dat feature

* I wish creating a spline the end point would be set after aborting the last section (where the first point is identical with the last point of the previous section).

I solved this problem today with the release of version 1.5.9.

Was any of you successful moving, deleting, manipulating the vertices of a reference line?

I have got a very interesting/funny behavior (which I need to confirm after a reboot):

- I have a PPT open
- I run an "Export DAT" from LDPC
- When LDPC finishes, my PowerPoint gets the focus again and an empty slide is added!

Re: [LDPatternCreator] Known Bugs?

I confirm this behaviour: while exporting dat, LPC seems to throw some carriage return to other opened apps.

May be this comes from using "Rectifier". As your tools say "press ENTER to quit" may be there is an additonal key-stroke being sent somewhere

That is correct. To be precise: The key stoke will be sent to "Rectifier", "Unificator" and "SlicerPro".
LDPatternCreator can sent this key-stroke to other applications, too.
This occurs, if one of the programs ("Rectifier", "Unificator" / "SlicerPro") lost focus during the export.

* LDPC will not load primitives if there are two blanks after the matrix instead of one. Try this:

1 1 78 -0.25 9 1.6 0 0 0 1 0 0 0 1.6 1-4disc.dat
1 1 78 -0.25 -9 0 0 1.6 0 1 0 -1.6 0 0 1-4disc.dat

Since the installation of Windows 10, my mouse wheel is no longer working with LDPatterCreator. I can't zoom in or out that way. I must set the zoom value manually, which is quite painful to work with.

Any idea?

Plus (+) or Minus (-) will modify the zoom value, too.
I have to investigate and reproduce the issue on my Win10 workstation.

edit: I was able to fix this and provide a new release soon.
