Re: Developing a spreadsheet based loaf pan
Considering the suggestions from above, there is no one yet I would like to utilize in an Entry-Level approach.
FYI:
I am continuing now on an alternate, possibly a little more redundant but more simple way - no need for replies at this time.
Thanks for your posts!

Re: Developing a spreadsheet based loaf pan
Hi @all,
could you give a hint for removing the remnants of deletions? I could not manage until now.
Anything visible in the .png having positive Y-values would have to be cleaned / deleted.
Thanks!

your loaf will become a baguette: the ends are open

Re: Developing a spreadsheet based loaf pan
It would have been even nicer if you had revealed how to remove the remains..

Re: Developing a spreadsheet based loaf pan
with the capture window you enter the 2 points together and you use the coincidence constraint tool, it is the 1st of the bar
in addition I discover that the vertical line is a duplicate

Thanks, was not able to completely follow - this probably is caused by my know how, language and terminology used.papyblaise wrote: ↑Sat Mar 04, 2023 10:12 am with the capture window you enter the 2 points together and you use the coincidence constraint tool, it is the 1st of the bar

user1234, could you suggest a viable path for 'entry-level' (as opposed to 'advanced-level') so I could more easily continue? I was running into various obstacles until now, which are not to be mentioned actually.

Re: Developing a spreadsheet based loaf pan
That is pretty hard, since i am in writing not good, but i try it. Also the forum addition is pretty limiter (for good reasons), so the fps of the short videos are not high.
Not shown, i used as zero point the inner middle point of a side, not the outside, seems to me to make more sense. Also the zero point is not in the middle. Normal i make it in the middle to use the symmetric, but for learning i do it not, to show, that a plane can be settled with constraints symmetric to the object and can be used for modeling.
First make a spreadsheet, give it values (at best with units) and give it good meaningful alias (maybe better as mines). Then you connect the vaulues with the sketch.
Same works with angles.
Then place the DatumPlane with expressions. For showcase, i use the length of the pad. Of course you can use the length value of the Spreadsheet directly, i only want to show, that is possible to use any property of an object. I attached the plane before to the XZPlane, so do not need to to change any placement angle and/or axis.
Then place the sketch of the cutout on the face without TNP. For that i use expressions. In the first sketch, i placed a helper point (expression driven), where the points should be in y position. Then i gave them a name. I use the name for placing them via expression. The zero point for the to placed sketch is sin the corner. As the DatumPlane before, i use the a good attachment plane before, so you must not use any trigonometric function.
Do not forget to set the angle! Then you can pocket the sketch, which his now always on the plane and the cut is rectangular to the plane. Then you can pattern it to the dead, it is still parametric and, as long the values gave sense, undestroyable.

Just said, this model is not for sheet metal, since it is not made this way, it is only to show how to use expressions and how to attach a sketch without TNP.

Re: Developing a spreadsheet based loaf pan
Whow - sooo much to swallow, let's see if I can make this
![Surprised :o](./images/smilies/icon_e_surprised.gif)
Thanks!
Working some more on this draft actually, just to learn that exactly for the beginners it may really be hard to work around TNP, depending on the task of course.
I'll be back soon with the loaf pan

Re: Developing a spreadsheet based loaf pan
Referring to your post and to the actual state of the model (an actual state is attached):
The major questions / tasks now remaining are:
- how can a beginner be prompted to use expressions without sweating ..
- accordingly edit the other topic (above)
- continue on the loaf pan along your suggestion
For the moment, some of your recomendations are used in the other topic. If you want, they are not altered, if you prefer to create another sample, I want to integrate it as soon as it is here.

Ok, this was done so, yes, to use symmetries.
ok, understood
This was done alright.
This helps a lot! Using it firstly in here (actual priority)
Will try so!
