The sign-in is to enable cloud saves, build with friends, wanted list export, upload to the Studio Gallery, shopping integration features like price lookup, and probably some other features I haven't thought of or have not been mentioned in the comments yet. If you don't plan on using any of those features then it isn't required to sign-in.
Since there doesn't seem to be a tool, I've written my own one. In case anyone else want to use it, check it out here: https://github.com/ChrZae/bricklink-xml-diff
Take care tho, it can only really process the XML generated by Stud.io, the XML-format itself has more fields which I didn't care about (also no guarantees it will always work correctly).
Stud.io only has a small selection of printed parts, but there is hope. Stud.io’s Part Designer tool can help you with your clown torso. Here’s how:
Using a paint tool (like Windows’ Paint3D), save only the center bit of the torso to a PNG file, using the above torso image as your master.
Open up Part Designer and choose the option to modify a part. Search ...
Both programs (Stud.io and LEGO Digital Draw) can read the LDraw extension (*.ldr).
I'm using Windows 10.
I have NOT ungraded to the Stud.io 2, but I think it shouldn't matter
in this case.
In Stud.io, we will be exporting the file into the *.ldr format.
In LDD we will be importing a *.ldr file to be readable in LDD.
In Bricklink Studio go to File > Export As > Export as LDraw...
Open the file in any text editor such as Notepad
Find the Bricklink part ID you want to replace it. It will be a number followed by a .dat extension.
If you have multiple identical bricks with different colours, check the colour id in the second column. Bricklink has a list of colour ids ...
According to SylvainLS in this BrickLink post, these are the answers to my questions:
You can find out which colors are available for a part by selecting a part, opening the Color Palette on the right side of the interface, and selecting the Hide unavailable colors option.
In the BrickLink catalog, part 99455 and many other EV3-specific pieces are set to ...
The BrickLink gallery also includes a number of builds of official sets, however many of them aren't titled with the set name, but may include it in the description. Sadly there also doesn't appear to be any versions of 31120 yet.
You could download the instructions and have the fun of virtually building it yourself ;)
I usually check at Eurobricks forums, as they have "Official Lego sets made in LDraw" topic, where community share LDraw files for digitally built LEGO sets. The list of available sets is rather limited since this a community effort after all.
At this point of time I couldn't find files for 31120 on EB yet.
Please note that I think that software preference can very often be based on many factors that are difficult to enumerate and sometimes even more difficult to express. That said, I think there are a few important differences between the two specific pieces of software that you referenced that could be useful for answering your question. (Also note that my ...
I would use the winmerge tool:
XML files are text files. You can compare two text files with Winmerge and extract the differences...
some manual labor would be involved if the same part is present in both lists but with different amounts, but I would expect this to be all rather straight forward...
You are almost there: Right-click on a part. One of the options is "set as origin". This centers the view on this part. "Reset origin" does exactly that.
Otherwise, navigation is done by rotation (rmouse+move), panning (space+rmouse+move) and zoom (scroll).
I usually use Rebrickable to compare whatever I need.
First, you need to create two custom lists (My LEGO > My Custom Lists). Import tool supports "BrickLink Stud.IO files" so no conversion is required.
Once you got your lists sorted you need to compare them using "Compare sets" feature (Sets > Compare Sets). While the name suggest ...
