design sequence of segments

[Anonymous]

I have difficulties in creating a sequence of segments.

In Sketch, I draw the first segment, then, before drawing the following segment, I try to assign length and angle; when I do that, most of the times, the first segment turns from black to cyan and  the following segment looks to be an arc, not a segment, also cyan.

I feel I am doing something wrong with the mouse: which is the correct way to do that ? Where can I find information with the correct use of mouse ?

Thank you.

it is hard to say for sure without a video, but, if you are getting an arc out of the line command, it means that you are doing a drag with the mouse, from the endpoint of the first line.  The line command in Fusion is a "click first point, click second point" interaction to get a line segment.  If you "click and drag", and if your click start point is on the end of another line, then you get an arc.  I can add a video if this is not totally clear.

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

There are a plethora of tutorials on the internet.

Here is one set...

Make sure you are doing click-click for lines and not click-drag (unless you want an arc rather than a line).

Jeff, thanks for the fast reply.

I understand your point, but how can I define the length and the arc degree of the first segment if I already went for the second ?

Thank you

Hi,

1. Show your process in a screencast.

2. share the file as @TheCADWhisperer  recommended

sorry, but I am not sure what you are asking.  Perhaps a screencast or video would help.  If you are dragging an arc in the line command, there is no way to input length/angle/radius, etc for the arc.  You will have to do that with dimensions afterwards.  Only the line allows you to enter length/angle.  Here is a screencast, but I suspect you already know everything that is in this screencast:

Jeff,

this time the first segment looks OK, but with the second segment started the problem.

The funny think is that, if I can can pass this stage, I have no problems in working even somehow complex design, following tutorials from YouTube; the fact is that say what they do, not how, and I am getting stuck with this.

I tried to follow the indications of the video you sent me.

I don't understand what I am doing wrong (i.e., what's the rule), because I can workout 2 consecutive segments, but at a certain point I find that the only thing I can draw comes out to be an arc (in cyan).

BTW, I changed the language from Italian to English (with a couple of products, this move solved problems), and I have found differences, not only in the translation of captures.

Thank you.

What happens if you add this 45° (or other) angle dimension?

I suspect that the issue is that you are attempting to add dimensions "on-the-fly" as you create the geometry.

This works for limited sketching, but for most sketching you will probably add the desired dimensions after sketching.

You are sketching in the literal sense of the word - then add parametric dimensions to define the geometry.

I recommend creating one line, rectangle, circle or arc and dimension immediately for a sense of scale for the rest of the sketch.  Then you can sketch and add geometry constraints and dimensions as needed.

Do you have a link to image, video, tutorial or some other reference that shows what you are attempting to design?

I feel you are right, but the fact is that, following videos and tutorials, I have to replicate in my Fusion what they are doing in their videos step by strep, and that's where the problem arose.

I'll try to manage the thing.

Thank you.

In that case, the fact is that it would be easier to answer your question(s) if you include link to the video and the timestamp where issue in following steps occurs.  Otherwise we are shooting in the dark with the hope of hitting on the right answer.

Hi,
Can you share what type of sketching is much relatable to your topic?
Thank you.

[shahriarsifat1802164]

Actually, I tried to add dimensions if the sketch has multiple relations then give dimension on each segment but when the sketch is very much straight forward I try to make the sketch fully then add dimensions.
Thank you.

Right now, I don't have a specific type of drawings, as I am interested in learning how Fusion 360 works and how to use it, as Thinkercad is not enough for my goal, which is to design RC model planes.

I know that Fusion may be a very good tool for that use, and I started to follow tutorials to shorten my learning period.

Therefore, any suggestion is welcome.

That's great; Then check it out though it is related to 3d modeling but you can get a good understanding during sketching.

Thank you very much for the link; I will check it carefully.

What I am doing now is to understand at my best how Fusion works, and that arose the problem, while following step-by-step the examples of the tutorials.

I understand that the best way to design a plane model is to start from a 3-sides images that should be as close as possible to what I want, and, from that start point, to modify and adapt Fusion drawings: the final goal is to obtain a file (.dwg, .obj, etc.) that I can give to someone that, with a laser CNC cutter, can produce all the components I need to assemble the planes.

I have found a couple of videos of someone that has done in this way, and the results look great: I think I will go in that way.

Every suggestion will be of great help.

That presenter violates some of his own recommendations (sketch is not fully defined).

I suggest that you model something (perhaps this paper clip) and Attach your *.f3d file here for diagnosis.

thanks for the video link, @Anonymous - the topic at that point in that video seems to be pretty straightforward line creation with dimensioning during creation.  But, it is still not clear to us where you are having problems with this.  Can you record a video of yourself interacting with the line command and show where you have problems?  You say you get an arc - the only way to get an arc is to drag with the mouse from the end of another line.  If you stay away from drag interactions, and instead use mouse clicks, you get only line segments, which can be dimensioned on the fly, or after the fact.  It is not clear where you are having problems.  We'd like to help but so far are not understanding the issues yo are encountering.

This is the .f3d file: to me, it looks OK.

Thank you.
