LDCad 1.5 How to know all the brick are stick (snapping?) together cor

[heryx]

I am trying to build some model but sometime can see a gap between 2 brick, example: when 3795.dat on top at 2456.dat.

1. is it really not fit ? what can i do when this situation happen? if i continue to buy brick base on my model and build it in real, will there have problem?

2. any way to scan all the single brick to see anywhere not snapping correctly?

Thanks

Just a little question before trying to solve your problem: did you actually turn part snapping on?

It's off by default. To turn it on, go with your mouse to the bottom left corner of the editor (where the 3 colored arrows are). A menu should pop up. Make sure that in the bottom left corner of the menu, there's a green PS next to the green AEP. If it's a red GS, part snapping is turned off. Click it to turn it on.

Also, a little tip if you're new to LDCad: try clicking (in the same menu on the right side) on TBL. It switches to SPN. TBL (trackball) and SPN (spin) are different modes of how to turn the model in the editor. Try both, I personally find SPN a bazillion times easier!

Thanks for your help, I don't know how to attach image when reply the post, anyway.i have turned the PS (in green) on beside AEP, but don't know why still look like that as my first image. i tried to restart the LDCAD, same result, However, if it just display issue but it actually work. i don't mind to keep going

Your model will stay as it is.

The snapping is for placing parts (either by moving them or new ones).

LDraw tools don’t test for collisions, parts can happily overlap each others.

As for IRL feasibility, LEGO bricks are made to allow for a little room between them. Also, they are more or less supple. Besides, CAD models are not always accurate. Therefore, some builds that do not appear possible in CAD tools are indeed possible with actual bricks (and vice versa). Beware though, some builds stress the bricks (prone to break or deform).

The 'trick' in LDraw modelling is to keep an eye on wondering coordinates from the get go.

While building with normal bricks this is done by keeping the coordinates rounded to multitudes of (x/y/z/) 8/10/8.

You can fix models later on (using shortcuts like: home, ctrl+home, shift+home etc) but it will be very time consuming.

This all is the main reason the little coordinate panel is visible by default.
