Right now the Open dialog defaults to /home if it's there, or the Qt default otherwise. It would be very helpful for users (especially new ones) if it showed the Examples by default. This could then be overridden by a settings file later.

Hi,
Launching CadQuery workbench "break" the current FreeCAD gui configuration of the user. I found it too much invasive...
For example I have normally Combo View, Python console, Report View and Selection View enable. After launching the CadQuery WB all this views are deactivate (except Report View) and the CadQuery Code view is still enable after switching to other workbench.

This would be normal operation within apps, but the module does not currently do it.

Hi,
A french user of FreeCAD have a problem on loading CadQuery workbench. His FreeCAD data are :

Is it a bug ? or what can I advise him to fix this ?

Adding these in the config file would prevent people who have compiled FreeCAD from scratch from having problems.

#45

when i switch to cadquery module, it pop-up "must be string, not None" dialog.

The files started from skeletons that were generated by the fcbt.py tool, and have the incorrect author, copyright and license information.

Hi.

As described here:

http://forum.freecadweb.org/viewtopic.php?f=9&t=3914&start=80#p103014

When i install CadQuery FreeCAD module (Ubuntu 14.04) and run one of the unrelated macros i get mentioned error (without switching to CadQuery WB first). I hope it will be obvious what could be causing the issue.

Posting this screenshot here so that I can link to it more easily.

PyQode allows for tabbed editing. It would increase productivity if you could have multiple editor tabs open at once so that you could do things like work on different parts in an assembly simultaneously or try out ideas in a "scratch pad" in another tab.

Pint is a Python units library which makes it easy to embed units in your code from the ground-up.

I've posted an installation tutorial video, and added it to the wiki.

At the time I'm creating this issue, it seems like YouTube is still processing the 720p version.

The CQ and PyQode packages need to be embedded with this module to keep users from having to install packages manually, which can be a very painful experience on Windows.

Hi, i just installed freecad and the cadquery-freecad-module.
Unfortunately it errors when i change the workbench to CadQuery. In fact it errors on all changes of the workbench, if CadQuery is in the Mod directory.

I attached a screenshot:

My system is Archlinux.
Freecad version is 0.15 revision 4671, installed from the official archlinux repositories.

BTW. i wrote a PKGBUILD for installing/uninstalling this module with the packagemanager.
When this works and you are positive, i would like to push it to AUR (Archlinux user repository)

Best, moeb

We're using CADQuery to create a panel with mounting holes, and we positioned the holes with coordinates. However, the relative positions of the holes are inaccurate. Here is an example.

# This example is meant to be used from within the CadQuery module of FreeCAD.
import cadquery
from Helpers import show

width = 100
height = 200
thickness = 2

# Create a plate with two polygons cut through it
result = cadquery.Workplane("front").box(width, height, thickness)

result = result.faces("<Z").workplane(offset=0).center(0,30).rect(10,10).cutThruAll()
result = result.faces("<Z").workplane(offset=0).center(0,-30).rect(10,10).cutThruAll()
result = result.faces("<Z").workplane(offset=0).center(0,-60).rect(10,10).cutThruAll()

# Render the solid
show(result)

I put the three rectangle holes at points (0,30), (0,-30) and (0, -60) respectively. The distance between the first rect and the second rect holes should be exactly 60, but I've got 60.1508. The distance between the second rect and the third rect holes should be exactly 30, but CADQuery gives 29.8485. I don't know what's wrong with my code. Very weired!

Qt has built in functionality to support multiple languages. There are a few spots in this module (i.e. Helpers.show) that don't make use of this functionality currently. This needs to be fixed.

Hi JM,
could you please check if the latest 0.18 release
downloadable at
https://github.com/jmwright/cadquery-freecad-module
includes the latest cadquery Lib?

if I download your master at
https://github.com/jmwright/cadquery-freecad-module/archive/master.zip
and I put CadQuery dir in Mod dir I get the latest, but if I download 0.18 release from the previous link, I think I will not get the latest

Thank you
Maurice

When i launch the workbench i get this window message error :
/usr/lib/freecad/lib/Drawing.so: undefined symbol: _ZNK3App17PropertyContainer7getNameEPKNS_8PropertyE

And in the report view I get this interesting information :

/usr/lib/freecad/lib/Drawing.so: undefined symbol: _ZNK3App17PropertyContainer7getNameEPKNS_8PropertyE
Traceback (most recent call last):

It seem that manually import Drawing workbench by typing "import Drawing" in the python console before launch CadQuery workbench make the workbench working good (at least it is launch without error)

OS: Ubuntu 14.04.2 LTS
Word size of OS: 64-bit

I prefer emacs, but I don't like having to re-open the file from a menu each time I make a change. The ideal solution would be to watch the open file and automatically refresh the editor if it changes. I realize that this might be tricky to support on all platforms.

A "reload and execute" button would be a distant second, but still a huge improvement on the current work-flow.

We want to create a paramatic box with editable covers and panels with CADQuery. However, the following code give us a whole box as an integraged part, and we cannot edit(e.g. hide or show covers and panels individually) the six faces individually. We're not sure whether CADQuery can do this thing. We know that it creates whole parts powerfully. If not, do we have other scripting options for this application? Thanks.

# This example is meant to be used from within the CadQuery module of FreeCAD.
import cadquery as cq
from Helpers import show

# The dimensions of the model. These can be modified rather than changing the
# object's code directly.
width = 40
height = 20
thickness = 2

# Create a plate with two polygons cut through it
top_prt = cq.Workplane("XY").box(width, height, thickness).translate((0,0,10))
bottom_prt = cq.Workplane("XY").box(width, height, thickness).translate((0,0,-10))
left_prt = cq.Workplane("XZ").box(width, height, thickness).translate((0,-10,0))
right_prt = cq.Workplane("XZ").box(width, height, thickness).translate((0,10,0))
front_prt = cq.Workplane("YZ").box(height, height, thickness).translate((20,0,0))
back_prt = cq.Workplane("YZ").box(height, height, thickness).translate((-20,0,0))

result = top_prt.union(bottom_prt).union(left_prt).union(right_prt).union(front_prt).union(back_prt)

print result.all()
# Render the solid
show(result)

Right now the CadQuery library is just copied to this module's codebase and committed. Doing that has become a maintenance headache. I can use CadQuery as a submodule, but it will require me to bring along a lot of extra files from that repo that I didn't want. I don't think that can be avoided at this point though.

When working through a heavy CQ script debugging session, it would be very helpful to be able to clear the "Report view". Otherwise the stack traces become overwhelming.

I was trying to draw a t-slot profile by drawing only a quarter then mirroring. But mirrorX doesn't seem to work. Please try below snippet:

from cadquery import Workplane
from Helpers import show

r = 20
d1 = 5
d2 = 8
s = 7
t = 1.5
H = 10

points = [
    (0, t/2),
    (r/2-1.5*t, r/2-t),
    (s/2, r/2-t),
    (s/2, r/2),
    (r/2, r/2),
    (r/2, s/2),
    (r/2-t, s/2),
    (r/2-t, r/2-1.5*t),
    (t/2, 0)
    ]

result = Workplane("front").polyline(points).mirrorX()

show(result)

It behaves like this in my case.

But mirrorY works as I expect:

This menu option should start a fresh file for the user, populating it with some skeleton text following the current best practices for CQ.

If you click "Measure distance" and measure something, the next time you hit F2 you'll get the following error.

Traceback (most recent call last):
  File "/usr/lib/freecad/Mod/CadQuery/Gui/Command.py", line 121, in Activated
    clearActiveDocument()
  File "/usr/lib/freecad/Mod/CadQuery/Gui/Command.py", line 24, in clearActiveDocument
    doc.removeObject(obj.Label)

No document object found with name 'Distance: 48.962'

If you delete the distance from the feature tree manually, the error goes away and the script executes.

A modification needs to be made so that distances are cleared automatically by the module before letting FreeCAD try to clear the active document.

I've done some work on the wiki.

https://github.com/jmwright/cadquery-freecad-module/wiki

It includes links to the Installation, Getting Started, and Troubleshooting sections so they can be easily and quickly shared with other users.

Helpers.show() is an improvement over Part.show(), so all the examples should be converted over to using the new function.

I like to give different parts in a file different colors so I can see them more easily.

Translucent materials are especially useful in visualizing interior geometry, but I don't know if FreeCAD's actually supports transparency. For a first draft, I would settle for being able to make different parts different solid colors.

Parameters: (Optional) Defines parameters and their default values, which can be manipulated by users to customize the object. Parameters are defined by creating local variables of a particular class type. Presets and groups organize parameters to make them easier to use

http://parametricparts.com/docs/fileformat.html

Things along the lines of:

• add a way to highlight the objects matched by a selector
• add a way to visualize the negative space in a cut (something like openscad's debug operator)
• some limited mouse interaction might be fun too:
  • use to generate a direction selector based on the current view, for example.

The operations seem to complete, but no text is loaded into the editor. The problem goes away after a restart.

With the way FreeCAD works, the following is an extra step that the user has to perform inside their script, even to use classes within the same module.

import sys
sys.path.append("/path/to/script/parent/dir/")
from script_name import ClassInSameModule

It would be very helpful for the module to do this for the user, and would set the module up to accommodate full project directory structures. Paths would need to be removed from sys.path when a file was closed though, or sys.path will contain unneeded paths in it.

I am using using FreeCAD 0.14, Libs: 0.14R3702 (Git) from the ppa:freecad-maintainers/freecad-stable on Kubuntu 14.
After extracting the current version of cadquery-freecad-module into freecads Mod directory I get an "No module named QtNetwork" error when I try to start the CadQuery Workbench in FreeCAD.

I do get the same error if I try it on a fresh Ubuntu 14.04 Desktop 64bit install.

If I run the script

a = 3
print a

then, in the same session,

print a

The second script does not fail as expected, probably because the global namespace still contains a.

Most examples have simple syntax problems like lines that are over length. We don't want new users to see that when they're learning CQ.

This will be a config file that the user will eventually be able to interact with via a dialog. Please post the items that you think should be in the config file here.

• Select a light or dark theme
• Set default directory for open/save dialogs
• ParametricParts.com user name
• Enable/disable experimental code. This would allow us to experiment with more difficult and far reaching features without affecting the non-power users, like adding CQ code to the editor by clicking a button in the GUI.
• Automatic save on execute
• Automatically reload from disk without prompting
• Automatically execute on reload

I love the easy install!!!!
Using the x86 installation, the CadQuery module on FreeCAD 0.14_3700, I see CadQuery in the workbench, but i get this error upon launching it:

"Module Object has no attribute QtWebkit'

Steps to repro:
(1) Deleted all existing freecad installations
(2) installed freecad 0.14_3700 ( latest stable)-- x86 version
(3) expanded latest cadquery module into Mod directory
(4) started freecad-- observed CadQuery choice in workbench.
(5) choose CadQuery view-- observe dialog with message above.

Right now a user has to type FreeCAD.Console.PrintMessage to get a message into the report view. It would be nice, and make the code much cleaner (and make scripts a cleaner fit with any future non-FreeCAD GUIs), to override print to provide the proper behavior. This should make scripts that are written outside the module slightly more compatible as well.

I think this can be done fairly easily using the module_locator.

Right now the FreeCAD document tabs (the 3D views) are left open even if you close or replace the script in the code pane. this essentially orphans the 3D views and can be confusing. The associated 3D view should be closed when a CQ script is closed or replaced. This will change when tabs are added, but tabs are aways down the roadmap.

The module currently closes the 3D view that's generated from execution of the script when the user switches away from the workbench. The 3D view should be left in place so that the user can use tools from the other workbenches on the model.

This module has been added to a third party PPA for Ubuntu. That installation method should be added to the wiki.

https://code.launchpad.net/~freecad-community/+archive/ubuntu/ppa/+packages

The installation section should mention that this repo has a great selection of other modules/workbenches for FreeCAD users too.

OpenSCAD makes it easy for users to access their Examples right from the file menu. It seems like it would be good to do the same with the embedded CQ examples as well.

Should experiment with import and reload again to see if it addresses these inconsistencies.

http://stackoverflow.com/questions/922897/nameerror-using-execfile-in-python

The new Helpers.show() function seems to be a much better way to do things than Part.show(). The new file template should be modified to reflect this.

It would be nice to easily access the scripts that you've worked with recently without having to navigate back to them through the Open File dialog.

Dear Sir,

I try to create a PhoenixContact's "DIN rail" with CADQuery inside FreeCAD, and I've successfully got the basic model. However, when I try to punch holes on the basic model, I've got error hints which I do not know how to resolve.

result = cq.Workplane("front").moveTo(-15,10).lineTo(-10,10).lineTo(-10,0).lineTo(10,0)
.lineTo(10,10).lineTo(15,10).lineTo(15,8).lineTo(12,8).lineTo(12,-2).lineTo(-12,-2)
.lineTo(-12,8).lineTo(-15,8).close().extrude(200)

Problem statement......

result = result.faces("XZ").workplane().circle(5.0).cutThruAll()

show(result)

Could you please give a hand?

Thanks in advance!

Youbao

Instructions for getting the module up to full working order need to be added for Linux, Windows and Mac.

Success! Instlallation works correctly on windows x64!
This thing completely rocks! It really really brings CQ to life!

One suggestion: I didnt immediately figure out that you do F2 to run the script. It was quick to figure out, but I think a good enhancement might be to populate the code view initially with an example that works, with a comment that says "press F2 to run the script" or something along those lines.

That's really the only thing that could have been easier! extracting the module into the Mod directory was easy and worked just right! its just SO awesome to see scripts in the window!

This is a HUGE step forward. If i can get this script format to somehow be uploadable to parametric parts, a quick menu option to upload to PP would be super-sweet.
