If he left off the fillets he could have made a 3D sketch converting the edges then add the rads to the 3D geom to get tru radius, another simple way. It's not just the arches that are a problem. The distance between the "Steps" is not the same as the length of the inclined sections. So i...

Unfortunatly this is Makers file. Not to open in commercial version

Krzysztof Szpakowski

Well, unfortunately, not all that glitters is gold. Easy but... When the walls tilt (draft feature), the dimensions and arcs change. So the arcs will be elliptical and trigonometry must be used to convert the vertical dimensions. But in many cases it can be useful. It is of course possible to use mo...

Not completely. It is stretched and compressed at the same time. Depending on whether it is the outside or inside of the bend.

Krzysztof Szpakowski

Doesn't it seem that instead of the pocket, the retaining wall of the spring could be tilted to provide better support?

Krzysztof Szpakowski

The other problem is that the helix feature can't use equations or reference geometry, Quick tip: Remember that you can get a helix using the Wrap command, using a triangle or just a diagonal line in the sketch. And in the sketch, equations and parameters or reference are not a problem. Additionall...

Krzysztof Szpakowski

So... Surfaces are an efficient way to do this. The main issue is that when you slice a cone at an angle, you get an ellipse. So, your branches have to transition from a circle to an ellipse. The attached model uses surface lofts to create the ID and the OD and the ends are then capped so that it ca...

Also, I believe ST1 has an incorrect pierce point. It is piercing the control point polyline and not the actual spline of the 'Lower chine curve' sketch. Not affecting anything up front, but worth noting. I admit that I did not analyze the entire model, because, as I wrote in the first post, the mo...

Krzysztof Szpakowski

A few questions: Are holes cut on the flat? So they're not "true round" after forming? Are the plate thick enough that after forming/rolling the bolt won't go through? If so, need to cut oblong instead of round hole. Bravo, Frederick, I wanted to write that myself. Holes are cut with CNC ...

Krzysztof Szpakowski

I wish I knew surfacic a bit more. These kind of shapes look awesome to develop. It's not as difficult as it may seem. And as I have written many times, designers often reach for the surface when it is not really necessary. Just like in this topic. You can create this hull as a solid avoiding many ...

Krzysztof Szpakowski

Well, doing it with SW is like 20 times more difficult than doing it with Rhino/Delftship/other NURBS modelers :D But having parametric model is just so awesome in boat design . Once you set up all these surfaces, you can do hundreds of iterations / design studies with CFD or stability/hydrostatics...

You have right. ST8 There is no tangent condition at the keel!
Also, I don't understand why this sketch isn't parallel to the others. This can cause contact errors on the small lower surface of the bow

Krzysztof Szpakowski

Thank you, this does result in a much smoother surface, but I can't set continuity conditions for Loft guide curves. Why not? Select the edges of the secondary surfaces as guides and give them tangency conditions. Also, in your case you don't need these surfaces. As the tangency condition, you can ...

Krzysztof Szpakowski

Quick tip: Swap profiles and guide curves!

Next tip: Look for information on how patterns were modeled in the workshop using steel strips in the past to obtain a continuous curve. This gives an idea of the flow "tension" of the surface.

Krzysztof Szpakowski

Sorry, the whiskey was long gone but I didn't have time (and I don't have) for a longer sitting. However, as I wrote, it is enough to quickly change the way of creating the main surface from Border to Loft and the surface after stitching and thickening is free of these anomalies on the keel. However...

Krzysztof Szpakowski

See you!

Krzysztof Szpakowski

As you can see, the geometry is not correct. The keel is wider at the bow than at the depth. image.png Moreover, the construction seems to be incorrect. As you can see, the theoretical waterline is completely different from your madel! image.png And the structure of your model does not encourage dee...

Krzysztof Szpakowski

I think the problem is that the two profiles are slightly different (circle and ellipse) and there are inaccuracies in the drawings. In my case, I used the same Sketch2 profile and unchecked surface blending and it worked. I recommend being more precise and avoiding surface penetration like yours im...

Krzysztof Szpakowski

The problem here is pipes or closed profiles. When I had to count the surface of profiles for powder coating or anodizing, I dealt with it by changing the internal contours of the profile to a construction line. This way you can deal with this problem relatively quickly

Krzysztof Szpakowski

As above, no problems with installation, use, login. However, I do not recommend installing the Makers version on a computer with a commercial version. The second one stopped working for me. However, saving on a computer (locally) is not a problem. Please also remember that the XDrive, XShape and Vi...

The model is very simple, but it's for studies so I won't show it. Let me just say that the projection is in the ANSI standard and may be more difficult to imagine for people who use the ISO standard on a daily basis. Remember, ISO is the view from the side we are looking at, ANSI is the projection ...

I use SW 2012 with Win10. It works OK but without RealView. But you don't have this function at all, so there's no problem. One important note. After installation and the first time you run it, wait until the program starts and then close it. When you first run the program, it creates an environment...

It looks like you have disabled automatic relations in menu TOOLS - SKETCH SETTINGS - AUTOMATIC RELATIONS

Krzysztof Szpakowski

I think you can add to the properties part. These, in turn, can be inserted into a BIM table, which can be imported into EXCEL.
Maybe this will be enough for you?

Wow! I didn't know about it. This is very valuable advice! I think I'm waiting for the next repair of the SW installation
Thanks again.

Krzysztof Szpakowski

Hi Frederick. No, I just installed it by disabling the antivirus before installation. When I noticed that something wasn't working, I uninstalled it with the registry cleaning option and installed it again. It didn't help. My VAR didn't help either. Only the changes from your link gave the result. T...

Hello I was forced to change the computer and therefore the operating system from WIN7 to WIN10.

It is also not possible to add icons ...

I've been 3D modeling since the early '90's. Using Solidworks since '97. Using anything from CAD Key, Alias Wavefront, SDRC and Pro/E.....

@Krzysztof Szpakowski So let me break it down for you to make it easier to follow.... Geometry Creation Features/Tools like Extrude, Revolve, Loft, Sweep.

Anyway, I gave it a try using boundary stripes and fill surfaces, everything has a tangency continuity (Yey 8-) ): image.png Your example is so simple that it can be done without using surface tools. We often complicate the task ourselves. Sometimes it's better to send a soldier on a bicycle with g...

Model half a turn and then array ;-)

Or use surface:

Krzysztof Szpakowski

Your drawing shows that the geometry intersects itself (Blue region). The Worm pitch is 2X4.7125 and the profile is 2x6. Cut the profile symmetrically to the pitch, or model the shaft and the part that is above the diameter of the shaft separately.

Library Feature limitations make this a headache... It is precisely because of the diversity of patterns that Lip/Groow works the way it does. No possibility of greater automation. The limitations you write about apply here. If you used it, you wouldn't have a headache, but maybe a finger ache. Fro...

Krzysztof Szpakowski

Yes, you are correct, it does (except for that little chamfer), but the issue is Lip&Groove can't be used in a Library Feature either, and setting it up for every single joint is just too tedious... I'm not sure what you consider a "small bevel" but if you're thinking about tapering t...

Can't you use the boss/groove command? It seems to do exactly what you want to achieve.

Hmm... A alien doesn't know...
I'm starting to have doubts...

Krzysztof Szpakowski

As Dwight writes, you can use Design Table. But there is another possibility. It seems that your main table shows the name of the part (file name - round part) and there should be the name of the configuration (round part - blue), so it will work similarly to Toolbox.
