Hello all. I'm working on a platform project for my son, and for the first time have downloaded a few pre-made components from 3D Warehouse. One of them is a joist hanger.

When I inserted the component into my project, I couldn't quite place the hanger onto the joist perfectly. Even with the Model Info increments set at 1/64", the hanger would either be slightly away from the joist, or slightly embedded into the joist. It probably wouldn't matter if it was slightly away in this case, but I want to learn to do it right.

I changed the Model Info format to "decimal", and set the increments to .01. I was then able to gradually move the hanger to where it was just touching the joist by repeatedly moving it with several moves.

I haven't been able to find any information about a keyboard shortcut, or any way to repeat the last action I took. It would be nice to have a quick way to repeat those .01" moves instead of clicking the "Move" icon, then moving the item slightly, then typing in .01 each time until the placement is correct.

Does anyone know of a quick way to repeat the last action you took? Thanks. Jim

I have also struggled with placement of models downloaded from the 3D Warehouse. Almost every time, I have to use the "scale" tool to resize it and then move it into place.

One thing that has helped me is to use the arrow keys to control the direction of the move. That seems to make the "move" a little smoother.

I have no idea how to create a shortcut key, so I will hang around to see if someone posts some helpful info.

I did an experiment that may help, Jim. I downloaded a Simpson joist hanger from the Sketchup 3D warehouse to try to replicate your problem and found it was rather awkward to position the hanger on a surface.

I selected the component and Exploded it under the Edit menu. Then, with hanger still selected I made it a new component, making sure that I selected the alignment as Glue to Vertical surface.

After that it was easy to attach where needed, copy and move it 16", and then typing "x5" (or whatever number you need) in the length box to repeat the copy and move operation giving me 6 hangers on 16" centers.

I'm not sure this answers your question but hope it helps.

OK, being a metoo kind of guy I had to try it. Pulled down the first match on "Simpson joist hanger" and had no problem positioning it on a beam I created. Maybe people aren't grabbing it on a point that would be making contact? Maybe snap to is disabled? Using guides can help a lot to get things in the exactly correct position. See the annotated picture. Sometimes SU can be picky about snapping to a surface so I usually like to have some sort of edge to help out. By placing the guides at the exact spot you remove all questions about position. The tape measure is far and away my number one tool (should be called the guide line tool).

What drives me nuts is the object will suddenly change size (mostly much larger) as I try to move it around and position it.

Yeah, that's a bit unnerving. It's snapping to things as you drag the nub (or what ever you call the thing you grabbed onto) around. I went so far as to turn off snapping at one point - very bad idea. Once I stopped fighting it and just looked for an edge or intersection to land on, it got a lot better for me. Now it's like second nature.

The other thing about this that bugs me is SU seems to be willful about which corner it will let you grab onto. With the hanger, I had to zoom in reasonably far to get the correct corner.

On the beam, I took the hanger to the top edge of the beam, it snapped in, and then slid it down the face. But guides really are the way to go.

Great tip, Oliver. It worked like a charm! That's the same Simpson hanger I used, and your method worked easily. Thanks. Jim

Phil..........I checked and snapping was indeed turned off. Why, I don't know. I appreciate your advice about that, and about drawing guides first, then grabbing a corner nub and dragging to the intersection. Thanks. Jim

Dave Richardson is a SketchUp genius. He has helped me tremendously. One thing that I learned from him is that many if not most of the models in the warehouse are not drawn correctly. Their reference points (if that's the correct term) are not in the right place. He exploded a model while I watched and properly located the reference point. The piece then dropped perfectly into the design.

I'm still somewhat of a beginner, so if I have misstated any of the above, it's my fault, not Dave's. The point is, make sure the reference point for the model is in the right place. If you're beyond the beginner phase in SketchUp, don't be shy about editing the models you download from the warehouse.
