Drawing Steel Plates and aligning them

Slimdog

Hey Slimdog, is see your also a vancouver-ite and welder. Im from Langley... I have seen quite a few of those help videos and are great. May have missed that one, will check it out thanks.

Are you doing shop drawings for someone or just modeling for fun?

I am doing shop drawings for myself. I already have what I am trying to draw finished in autocad and also sketchup. A friend of mine did the sketchup part, now I need to learn it so I can make more drawings.

Here is what we designed.

I think construction lines would be the way to go.

I'd like to see the SKP file but it looks like that model could use some help.

So if I was going to draw this thing in SketchUp as individual plates, I would definitely draw the plates in place rather than drawing them and then moving and rotating them. It would be a lot less work that way and less prone to errors. Since it is symmetrical, I would also only draw half of it.

Apparently he did only draw half of it and then mirrored it for the other half. And the plates where drawn in place and rotated from what I was told. That's the way I would do it anyways.

Hello

I use 1/4" steel plate in the designs I make from Sketchup. My Avatar is an example. Note, Since I am using 1/4" steel plate, I don't even use the plate thickness. I use zero plate thickness. I found it is a lot easier to make the designs and the welder just butt the inside edges together and make a weld on the outside in the gap between the plates and another weld inside between the plates. No problem.

It is a thing of beauty to see two pieces, 14' or more feet long align right up correctly at some weird angle.

Looks like a cool project speedy1.
If its going to be 1/4" plate it's going to weigh a lot.
What kinda truck is it going on?
Personally if I was doing it I would model each plate with thickness.
Are you guys cutting the plates by hand?

Speedy1

I have built one of these and mounted it on a truck. Turned out really well. The 1/4 plate is for the front part that has the winch going through it. It also has to be able to take the brunt of a impact. The rest, top and sides are all 3/16 with a total over-all weight of 120lbs. They are build for dodge trucks.

The plate thickness is set to zero I believe. Everything worked out quite well. As Ken said, it fit together with out any thickness issues and was corner to corner. I cut the plates with zip cuts but now I am going to use a torch. (was out of oxygen on the torch at the time) Once I get some money together, I'm going to get a plasma.

I think the biggest issue I face now is drawing in the direction of axes. I get turned around easily and draw shapes on the wrong planes. Is there a way to take a shape and change it to say "Front" plane?

I like the small house(s) idea for view angles.

Slimdog

Ouch zip cuts. Oh well use what you've got. I once built a nice aluminum bumper for a costumer. We test fit in and he liked it. So I measured between the frame rails and centered the mounting angles on to the bumper the next day. When he showed up we mounted the bumper and the mounting holes worked out great but the bumper was out of alignment on the body by a 1/2". Stupid frame rails were offset from the body. So I had to cut the mounts off and re weld them in the right place

Select the face and right click then pick align view. That will make the face you are working on directly in front of you. I would also recommend using a separate layer for each plate.

So aligning with the axis is like rotating on the axis. Sweet, thanks.

Ya went through 21 zip cuts when it was all said and done haha. Had them laying around from previous jobs I have done or worked at. Now I have a new oxygen bottle, Im hoping it will be cheaper.
