angled arc

[CFDruss]

Hey all, how is the best way to create a angled arc. I.E, say the arc is created on the xy plane, but you wanted it to tilt in to the z axis aswell???

Sorry for the noob question

 

[ewh]

You can define the plane in the orientation you want the curve to be before you create the curve, or you can rotate the curve after it is created.

thank mate, done the transform rotate way you said. One thing, I am makeing a exhaust system, have 4 outlets, and first 2 sets of outlets contect into each other, now i have created an angled arc and sweept the exhaust diamter round and united the two together. how ever on the other two Im trying to do the same to, I sweep one circle round the arc, then when I sweep the next circle and it gives me the option to unite to the other pipe, I click unite and it asks for a name instead of just doing it.....where am i going wrong here???

Thanks

Have you tried just creating all the bodies, then uniting them as a separate feature?

no, would that be a better method of doing it. #

Basically i have 4 exhaust outlets (circles), they will then be pair up in to one down pipe (so left two joined and right two joined). The plan was to do this via the sweep function and unite, then the two new down pipes to be joined into one. Do you think it would be better to create the pipe with out uniting, then unite then after all pipes are dont??

Why unite them at all. From a manufacturing standpoint they are four separate tubes going into a 4-to-1 collector. The collector would be a separate piece.

Try using assembllies and put each pipe and the collector into their own detail files and then bring them together in the assembly file.

well im creating it for CFD, so basically I need one complete volume, solid

 

[CFDruss]

can anyone tell me, I seem to be having a noob problem. When i select a circle, it selects another as well when i only want to select one, how do i stop this or select just one. Sorry

 

[Azrael]

Is it a sketch or other feature based curve? Try to filter for just curves

 

[Xwheelguy]

If you let your cursor hover prior to picking, it will change so that you see 3 small boxes....this indicates that multiple objects are detected & should help you cycle through the objects by continued MB1 clicks.

Depending on the operation, you may need to change the selection intent toolbar from "add tangent change" to "single"

 

[CFDruss]

Im basically trying to select a circle to apply a sweep operation on, but its selecting another circle too, and i dont want it to, how do I prevent this. I dont get the 3 small boxes you suggested Tim.

 

[cowski]

To get the 3 dots make sure you have preselection turned on in your selection preferences.

But - if you only click once and it selects both circles, it sounds like preselection isn't the problem.

Nice catch, cowski....not used to such a green noob....no offense either, CFDruss.

Hi, no offence taken, people have to start somewhere, and I learn a lot better from peoples advice than from books, rather be a team than an indiviual stuck in a book. The preselect was already on, but in the end, I just located the name of the arc and inputed it in the name box manually, seemed easy enough, and now my fist drawing ever, an exhaust system, pretty easy to you lot but im quite chuffed with it. Although there was a section of pipe that i wanted to taper between two defined circles, but it just did not seem to want to do it, any suggestions??? In the end i just had the pipe step in areas, Obviously would cause recirculation of a gas flow, but for my first drawing Im happy so far Now for a full engine block!!! haha, yeah right!!

 

[Xwheelguy]

When you tried the tapered pipe, was it twisting? If so, you may wish to split each circle into 2 arcs in the exact same manner. This will give points to align when performing the sweep & as long as you're selecting the arcs in the correct order, should prevent any twisting.

And BTW, we've all been new to UG at some point in time & I'm sure there's plenty of people out there who've had to go through the rigors of self-teaching. Hang in there & keep experimenting while following along in the documentation.

Thanks tim, your help is making a lot easier that it would be with out such feedback. Mnay thanks to you all.

I the taper by, having two circles, about 5 cm away from each other, and of different diameters (small on above the larger one) I then tried to taper by selecting both the circles, but it just came up with an error. I then adding a qaudrant point to each circle and join them up to try to taper the top circle along that line, but instead of tapering it it just extruded it at an angle??

 

[cowski]

If it is just a straight pipe that you want to taper, there are a number of options available. The extrude command allows you to specify a taper at creation time, or you can do a straight extrude and add taper later (with the taper command, if using taper from edge - only select one circular end of the pipe), sweep along a guide, revolve, you could create it with freeform through curves or ruled, and there is the freeform swept feature (and there are probably a few options that I missed).

Your options narrow considerably if it is a bent pipe that you want to have tapered. If this is the case I would recommend either freeform swept or through curve mesh.

thank cowski, i see what you mean, I didnt think about the revlove command, that would probably be the easiest. thanks mate, your a star
