Ive had a quick look and see what you mean about the warping..that needs thinking on..
I would reccomend you put all the bits into their own layers, then you can turn them off and on and work on them without messing up any of the other bits.
Its also quicker to just build one side of your model them mirror it..

For all you sketchup modelers, planes, boats,cars a thought just occured..(these things happen)...

Why recreate whats already been made... by that I mean why not collect parts from other designs by taking them apart and then saving them to your components library.

It makes no sense to me, to have to design from scratch what someone else has already made..

After all a wheel is a wheel, how many different styles have been done ? check with models in the download galleries, one must suit you, all you need is to size it to what you want..

Its the same for any other item, find, simplify or modify, rather than building from scratch..

I may have missed it in this thread, but has anyone mastered landing gear wire and other wire objects in SU and shared it here? That is what I am trying to do now.

SU newb,
Ken

I havnt seen any, my bends are just lines to illustrate the bends

Wire UCs are just a small circle pulled along the line with the 'follow me' tool, then use a metalic material to paint.

one of the youtube demos does the 'follow me' tool, when talking about keeping your models simpler.

this thread has a lot of usefull bits

I don't have a component library (or at least I don't think I do) but have been known to "steal" parts from my other drawings. It's kind of like using subroutines when programming and saves a huge amount of time. Cut and paste too. The mirror trick also saves lots of time.

When doing landing gear wire I think we will have to approximate. Wire has a minimal bend diameter (just like foam) and there is no good way for Sketchup to account for this, well that I know of. It would need some type of advanced plugin. So I draw the wire with a single line, then rotate the line to something straight so I know the length to cut the wire. It will be "close enough" but not perfect.

I found the ARC function perfect for showing bends in wire. First click on some short distance (i.e. 1/8") from the joint on one line then the same distance on the other line and click (SUs green dot shows where) then the red arc shows perfect spot to bend it. Final click and delete "extra" segments. Dimensions of initial lines determine length.

It would be advised for anybody working with Sketchup to spend a little time in the 3D Warehouse. If for no other reason to get some ideas. There is allot of very interesting stuff in there and it is amazing what people have done with this software. I have to admit that I have a tendency to fall back on my architectural back ground when I go there. I am thinking of rendering my Senior year Drafting final just for practice. Maybe even sticks and skin just for the heck of it.

Do a search in the Warehouse for "RC aircraft". The first item that comes up is Crash Mans render of the Blu-Baby by Tony65x55.

You will find your components library under the windows menu..click to activate.

under .....program files/google/google sketchup6 ..you will find the components folder...

add a new folder (model parts) to this folder and save your parts in this new folder..

the new folder will show in the components menu..and your saved parts will show in it....

Break down any designs for usefull parts...remember its all about scale.. a full sized engine can be scaled to our model size..etc...

here are some good components to start with..

..they are from this thread..

And more..notice the time between this and the last post..thats how long it took to download a model , remove some good bits, sort a pic, zip and post..Remember to make the items you find into a component then you can save them out..With luck this has already been done by the designer..
Save your components in your model parts folder that you should have added.. and away you go

Time to go back to plugins.....

heres a usefull tool...the constructon line tool....draws a dotted line that wont make faces..

guidelines, centre lines, etc its use is that you can use this and the tapemeasure and the protractor to lay out a guide to design your model. Then use the proper line tool to make the faces etc

heres a tool that will explode everything, all groups etc..in one go.. usefull for getting to all the bits when they have been locked up

3D wire landing gear


All right,

I have the wire making method down pat. The trick is to create a centerline path to follow for your wire. On the end of the wire make a circle by picking the end of the wire as the center for the circle, then type in the wire radius and hit return. Now reselect the entire wire path, click on the follow me tool, and then select the circle face. The wire with diameter is now created. Here is how I learned thanks to bz1mcr.

The part on the video I am referencing is about 40 minutes in.
