Hi all today someone asked (again) if there is a mac version of LDCad.

I advised the usual try a virtual machine, but this time I also thought about WINE as there is a mac version of that.

This made me wanne try running LDCad under wine in Linux as it should be the same I think.

So with some tweaks I did manage to get LDCad 1.5 running under wine on Mint 8,

It acts a bit weird the first start though but the second seems ok, only problem is no text rendering (so all crosses in the menus etc).

This was fixed by coping the FreeSans.ttf and FreeMone.ttf font files into the default/gui folder though.

The fun was then spoiled by it crashing assoon you start a new model, but this might be the result of me running mint in a virtual machine using software rendering.

Has anyone else tried running LDCad under WINE on Linux or a mac ?

update:
The crash was caused by using  std::locale envDef("")  for some reason, I managed to fix that by using std::locale envDef("C") this combined with the option to disable file monitoring seems to make WINE usable combined with LDCad 1.6.  I will need to do some more test though, any additional findings from experienced Wine users will be appreciated.

update2:
found a better way to fix the fonts issue, just symlink the systems font root dir into the wine/drive_c/windows/Fonts folder, like shown on the below picture.

LDCad 1.6 beta 1 running under wine on mint 18 which itself is running under vmplayer on Windows 7 Pro 64

Hi Trevor,

Making instructions I have found some "bugs" in LPub3D.

Model Description does not respond to placing it somewhere relative to the page
For example:
0 !LPUB PAGE MODEL_DESCRIPTION PLACEMENT LOCAL TOP PAGE INSIDE
0 !LPUB PAGE MODEL_DESCRIPTION PLACEMENT LOCAL TOP_RIGHT PAGE INSIDE
do not work and keeps placing the description top left

Setting an automatic piece count gives wrong count
Most of the time in an MPD with multiple submodels and multiple usages of certain same submodels.
For example the model I am working on now has 768 parts and LPub3D gives 753.

Assembly margins in a callout only seem to affect the top (or bottom) margin
Horizontal margins have no effect. Setting a margin in a call out separator gives odd results too.

If I find more I'll let you know.

Hi all,

Is there a sticker with the LEGO logo? Like this:



I know it is hardcoded in some parts. I did one myself: 3004pt6.dat :-)
I could extract it from there and it would be scaleable.

Hi,

I'm trying to reproduce the following assembly with LDCad : http://farm8.staticflickr.com/7024/68033...6f6a2c.jpg (part of this tutorial http://www.eurobricks.com/forum/index.ph...opic=60907)
This would require to rotate each half of the hinges by exactly 16.363 degrees (using 11 hinges, it's (360 \ 11)\2).
Unfortunately so far I've only been able to rotate by steps of a minimum of 1 degree, is there a way to rotate by an arbitrary angle ?

The closer I've come to reproduce the model is by using 12 hinges (that comes down to  a 15 degree rotation), but I'd really like to make an 11 hinges one
This is my 12 hinges attempt : http://tinypic.com/3ia4it61

Thanks

Hi Trevor,

When using pagenumber in alternate corners (like a book) the Submodel instance count is at the wrong place when it is on a odd page number on a single page submodel with a step group.
Using this
0 !LPUB PAGE SUBMODEL_INSTANCE_COUNT PLACEMENT LOCAL BOTTOM RIGHT PAGE_NUMBER OUTSIDE
does nothing.
Neither does dragging the instance count.
Also setting the font and size have no effect.

Can you fix this? Or is something wrong with my file?
Example attached.

Hi Trevor, and others who might be interested

The new feature to set local page orientation works on screen, but not in the output in PDF or PNG.
I start with A4 portrait orientation and somewhere I set some pages to landscape.
The PDF and PNG output are all portrait size but the content of the page is landscape and cuts off.

I post an example shortly.

Thanks

This walkthrough will demonstrate how to generate a LDCad Set part bin using my fork of BrickUtils.

You can download BrickUtils2.5.exe or BrickUtils2.5.jar archive distribution.

As set is defined as the collection of parts needed to digitally configure a model.

A set part bin will contain a set's parts and, optionally, quantity of each part.

This walkthrough will use example set LEGO Technic 42046 - Getaway Racer.

You can also download the 42046-01.zip walkthrough archive.

1.   Download Bricklink Set xml file
1.1 Be sure to check the "Inventory" radio button
1.2 Select "Set" at the inventory dropdown dialog
1.3 Add suffix "-01" to the set number and enter into "Item No:" dialog - e.g. 42046-01
1.4 Select "XML" at the "Download Format:" dropdown dialog
1.5 Rename S-42046-01.xml to 42046-01.xml

2.   Do Google Image Search for "Technic 42046.png"
2.1 Select and save .png image (best with transparent background) as 42046-01.png
   

3. Import 42046-01.xml into BrickUtils using "Bricklink XML dump" menu button 
   

4.   Configure imported set data
4.1 Define set attributes using search dialog button
4.2 Click "Search", enter "42046" in "By set #" dialog and click "Search"
4.3 Select available row and click "OK"
4.4 Remove extra parts and sticker sheet
   

5.   Map missing LDraw part numbers in "Part Mapping" tab(as necessary)
5.1 Parts with missing LDraw number are automatically transferred to the "Part Mapping" tab
5.2 Delete sticker set from part mapping
5.3 Search for parts in LDraw part library
5.4 Add part to part mapping
   

6.   Rebuild working list
6.1 Confirm no more missing LDraw part numbers
   

7.   Generate part bin (.pbg) file
7.1 Export parts bin set .pbg file using "LDCad Parts-bin Set" menu button
7.2 Select "Include quantity" set option if you want to see in the LDCad parts bin the quantity of each part used
7.3 Save file as 42045-01.pbg
7.4 Confirm Save status
7.5 Open .pbg file in text editor and confirm image name - e.g. 42046-01.png
7.6 Copy 42045-01.pbg and 42046-01.png to ".\LDCad\partBin\default\sets"
7.7 Launch LDCad and navigate to part bin: "Part Listings of LEGO Sets/Parts in the 42046-01 set"
   

8. Configure your model !
   

Note: The .pbg notation for adding LDCad template parts are as follows:
- wheel_15038+44771.ldr:[sourceInv=templates] [color=0]
- path\technicFlexAxle.ldr:[sourceInv=templates] [color=0]
- shortcut\hinge_2429+2430.ldr:[sourceInv=templates] [color=72]

Cheers,

Hello I am completely new to LDCad and would like my students to learn modeling their Robots using the LDCad software. I don't know how to get the EV3 Core and Expanded Set parts included in my LDCad Editor interface. By EV3 Core and Expanded set,  I am alluding to parts such as Motors, Sensors, Axles, Beams, Connectors, etc. etc included in the Core Set (45544) and Expanded Set (45560). 

So far I have successfully installed the following components of LDraw : 
a) LDCad b) POV Ray c) LSculpt d) MPDCenter & e) LDFind. 

Can someone please guide me through the steps ....

Thanks & Regards
Ankur Gupta
