Fusion 360 solids editing edges

[fabian.borg]

Hi,

I am new to Fusion 360 and would like to receive guidance to a problem I have. I need to have the ability to edit edges and or vertices of solids. I have seen tuts on getting this done by using forms, t-splines, etc. but somehow these are not getting the job done right. The model I am designing is a blocky type, (solid extracting from sketches) with cut holes and its full of right angles etc. hence when I convert from solids to t-spline (BRep to mesh), the model gets distorted badly.

All I would need is the direct ability to manipulate the edges of the solids and retain the shape but somehow I don't quite think its possible with Fusion 😞

Maybe I am missing something, hence please guide.

Hi,

Without seeing anything of what you want to achieve, we stick to the crystal ball.

I have uploaded a screenshot of a solid extruded from a sketch and highlighted the edges I wish to edit (pull or push, etc).

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

And if you have any images of something similar that already exists in the real world - include that information.

... fillet, chamfer or individual contour?

Hi @g-andresen 

Its edge pull, push move (angle) or better still vertex edit, a bit like 3DS Max capabilities on poly edits. I have uploaded the file too with the original post.

Thanks

Hi,

References to tools for other applications will not help us here.
Show how a comparable result on a real object looks.

Where are your dimensions.

Why are your sketches floating in space rather than reference to a datum?

to answer your basic question here:  No, you cannot edit a Fusion solid body by manipulating edges or vertices.  Fusion simply does not work that way.  That technique is available in Form/TSplines, as you've noted, but not in solid bodies. In a Direct Model environment in Fusion, you can directly Move solid faces, and Move includes the ability to rotate faces, but that is likely not to get you the interaction I think you are after.  In a parametric solid environment, you have to construct the shape you are interested in using a set of construction tools and feature history.

In the image you posted, what edit do you want to make to that edge?

If you tell us what you want the result to look like, you will get lots of input on how to achieve that.

I don't know any CAD software that works that way and I know quite a few 😉

@TheCADWhisperer 

Thanks for the insight on the lack of dimensions of the sketch and great video tutorial indeed. The sketch is a dxf import generated through Adobe AI. Is there a way to dimension the dxf sketch, rather than drawing a new open please.

[fabian.borg]

@jeff_straterthanks for the insights. Currently I am training to learn Fusion 360 hence I am not making use of real world objects (too noob to attempt reverse engineering) but keeping to basic body (solids) and sketches. The latter imported from Abobe Illustrator. @TheCADWhisperer informed of missing dimensions of the dxf sketches, so I am trying to figure that out too.

In my screenshot, I am trying to lower the top highlighted edge of the solid by -10mm and in reverse, raise the lower highlighted edge by 10mm and aim to retain the faces symmetrical.

Right click sketch.

Select Edit sketch.

Add the missing dimensions.

Edit the dimensions as desired.

@TheCADWhisperer   thanks, hopefully I sort one of the issues. Will follow your video tutorials 🙂 This will surely come in handy as I got stuck with cutting planes in an attempt to modify the solid.

If you have more experience with 3DS Max - model it in that software and then Attach your file here and someone will demonstrate the most efficient technique using Fusion.

@TheCADWhisperer  unfortunately, I no longer have access to the licenses of a past endeavor I used to poly model for. I am now starting my own little hobby luthier shop, and past varied software considerations and license costs, I opted for Fusion 360. Hence I cannot produce the desired output on another 3D application. However in my reply to @jeff_strater I mentioned that with reference to my uploaded screenshot I wanted to lower down the highlighted edge by -10mm and raise the lower highlighted edge upward by 10mm and obtain smooth slopes of my existing top and bottom faces.

Will try and produce the desired outcome with a photo editor

[fabian.borg]

@jeff_strater @TheCADWhisperer @g-andresen  I have created a wireframe illustration of the desired solid, apart from lowering the top edge by 10mm and raising the lower edge by 10mm, I need Face A and Face B adapting to the deformation, in this case sloping.

This would all be easier to decipher if dimensions are used. (See Attached file).

Once the true Design Intent is understood - I am sure an even easier solution can be presented.

(I didn't add the arc at one end until we nail down the Design Intent.)

Of course you can do this using direct modelling(without forms)

1. Show the sketch in your design, hold the edges or vertices and try dragging them until you are satisfied with the output. the model will update as you move the edge or vertex.

you can perform the same operation using the forms.

2. Draw the profile and extrude it using forms.

close the profile using fill hole maintain creased edges. watch the video attached you'll get basic idea.

Hope this helps.
