I need to assemble 2 sets of bricks, LDD doesn't...

[marsu211]

Oops! Sorry mught be at the wrong place.

Can someone move it to the "bug reports"

Thnx

Hi,

I need to assemble the bricks as shown in the picture.

In real life it works fine and without forcing.

I need this being done a couple of hundred times...

Can anyone tell me if this is a bug, or if there is a way to get LDD accept it?

Thank you in adavnce for your support.

I made a quick LDD model similar to the one you showed, and I could not get the parts to fit tight either. There must be a "bug" whereby the Technic 1/2 Bush cannot slide all the way tight against the center of the brown pieces. There is this small gap in LDD that cannot be closed (but CAN be closed using real bricks).

[Superkalle]

Can you attach the LXF too please. I'm not just being lazy, it's always better to look at the specific LXF at hand.....

....ok, ok I am lazy

Anywayt, to attach a lxf, zip it or just change the fil extension to .ZIP.

If this is the case, it's probably the same bug that makes it so that clips don't like to be centered on handles, as in the case of 48336 and 60470. The points at which the connected parts auto-align are programmed badly. It's a problem that bothers me a lot, and whenever working with clips and handles I always create a scaffold just to be sure nothing goes wrong.

I wish to be able to attach the lxf file, but have already used 93% of my upload rights!

How can I have more upload limit?

Thx

Attachment function of the forum is used for "temporary" files (it is a faster way, but the space limit force you to often delete files to make room for others).

For all other files, use an external file hosting.

Brickshelf is the most used file hosting for images and lxf files. Almost all users use it in the "Official Lego sets made in LDD" topic, for example.

For more generic files, you could use file hosting services such as fileden and mediafire.

Additional info to my original problem.

I have now replaced the 8M axle wit a 9M axle and removed the 1/2 Bush.

Same issue, it does not want to connect.

Reason why I used a 8M axle with the 1/2 Bush, is that the 9M axle does not exist in black!

Thank you for additional support.

PS: Thank you for the info regarding file uploads. I will put my images on my server.

One more question,

what do you mean by "I always create a scaffold"? Might this be a way to workaround my issue?

Thanx

It means that LDD is not able to place a brick without a connection, so if you want to place it where you cannot connect it (for example place a brick over a tile), you have to create a scaffolding where to connect the brick.

After that you remove the scaffolding leaving the brick in the position where you placed it (even suspended in the air, if you want).

In this topic you can find different type of scaffoldings created to solve a similar problem.

Specifically, the scaffold I use for clip-and-bar hinges can be found in this topic (you may have to scroll down a bit). It involves getting the parts aligned first, and then hinging them into place. On that note, let me see if it is possible to create a scaffold to solve your problem. I probably won't put it in the LDD Reference topic because it's a very specific problem, but I'll happily share any solutions I find in this topic.

EDIT: Here are the directions for getting the parts to connect:

• Step 1: Build this model on LDD. The axles on the ends can be any length.
  
  
• Step 2: Delete the two axles on the ends.
  
  
• Step 3: Hinge each reddish brown hub piece 90 degrees.
  
  
• Step 4: Delete the dark stone grey clip pieces.
  

This is basically the function of a scaffold. It consists of temporary structures used to "line up" parts of the model correctly. Scaffolds have to be different depending on the task, so it can take some creative thought to come up with one that performs the task you need accomplished. But in general, creative use of scaffolds and the hinge tool can help you connect things that LDD tends to have difficulty aligning.

WOAH!

Thank you very much for this instruction. You must be a genius, at least you are mine.

I'm still...don't find the words.

BIG THANK YOU, you made my day.

PS: subsidiary question, is it a bug or not? and if it is, will there be corrections in future releases?

Yes, I'm curios too. What do you say Aanchir - what is the reason it will not fit withoug scafolding?

[marsu211]

To All,

Well, the issue is not over yet!

Attached a new LXF file for current situation.

After playing around with Scaffolds and so, I am stuck at closing my square.

Use with respect.

It appears that the parts move in angle and these can not line-up correctly. When removing the base plate, or any plate used as it's base, the closing of the square might close, although not all parts are being connected.

I need the plates as a base for my construction, and wish parts being connected together.

Again, thank you for your efforts and your help already given and thank you in advance for future support.

Best regards

Patrick

It seems the two "arms" are disaligned, I think you can easily solve your problem cloning one of that on the other side.

[Bojan Pavsic]

The problem that you have is not with the axles or 2L connector, it's with the 1/2 bush or the X part.

You can easily create the square without the bushes (without any scaffolding), but can't add them afterwards, because the gap between the 2L connector and the base of the X part is just a bit too narrow.

It is possible to create it exactly like you want (with scaffolding), but after you save & re-open the file, the X part will be gone. Similar thing happens when you select the parts and clone them. LDD clones them without some parts, either the X part or the bush, but never both together.

I'm not sure if the parts are under stress when physicaly created like that (so illegal build) or it's just that LDD part glitch. I'm more leaning towards the first one (illegal build), since if you look at the parts carefully in LDD, the bush cuts into the X piece. I even tried to rotate the horizontal axles by 45 degress (to better fit the curvature of the X part), with no go.

[Calabar]

There was some kind of error in your file, probably you have placed or moved piaces using arbitrary angles or linear distances.

So, I did it from the scratch in few minutes, and without the use of any scaffolding.

Here is the result.

[Superkalle]

I don't know if something wrong the placement of the bricks in this particular file, but this is what I found. The ends don't seem to meet up.

[Aanchir]

Yes, I'm curios too. What do you say Aanchir - what is the reason it will not fit withoug scafolding?

The reason would seem to be, as I said, the same problem that causes an "offset" in clip-and-handle connections. Basically, LDD has only a certain level of precision with Technic axles and 3.2mm bar pieces. To be specific, LDD can only connect pieces along these bars or axles at 1.6mm intervals. The problem emerges with a lot of handle pieces (and evidently, with this four-way hub piece) when the "starting point" of the pieces isn't centered correctly for certain types of connection. Thus, there will be a <1.6mm offset in either direction from the ideal point of connection.

The hinge tool can compensate for this because the parts can be aligned in ways other than a direct connection before they are finally attached to one another. Of course, certain clip parts like the now-removed Mars Mission alien parts from version 3.0 were mind-bogglingly frustrating when trying to build a scaffold.

Whether or not this qualifies as a bug is a matter of opinion. After all, there may be connections between certain pieces that would require a different alignment on the pieces, where the current "offset" would be ideal. The way to solve this problem completely would be to increase the precision of LDD's connections, allowing for a smaller interval between automatic attachment points. But even this would come with a cost, as the smaller interval between attachment points would make it harder to judge whether or not a part is in fact aligned as you intend it to be. It's definitely a problem which I think should be addressed in some way, though, particularly in the case of clip-and-handle hinges. In the case of some, like 48336, it seems as though TLG may have actually fixed the problem during the last update, as there is no longer an offset, but the offset problem is still visible in other parts like 60478.

[Calabar]

That's exactly what I mean with "disaligned" in my post #14!

You image is surely more explicative.

Hi,

Thanks for the replies,

I am designing in LDD what I have physically built in real. No stress, everything is fine.

As I also said in a previous post, is that I removed the bushs and the 8M Axle and replaced with a 9M Axle, the same issue appears in either ways.

I have cloned, the 2 on one end then tried to connect them, no way, it does not work out.

I wanted to make a scaffold, which works as long as I dont use any plate as a base. Once I get my square, I can't add the bottom anymore, because the 4 Bricks diam.16W with cross won't line-up with the base.

Well thx again for the effort. I continue working on the real model.

Best regards

GREAT!!!

I owe you something.

Sorry haven't seen your reply befor the other ones.

How have you done this?

I started from scratch also, but did not end-up as this good. It's PERFECT .

THANK YOU
