Sketch/Volume specific parameters

[Anonymous]

Hi all,

I would need this to create different sizes of my sketch/part by changing only one parameter.

Situation:

I have a sketch that is fully defined by user-parameters. Let's assume for simplicity a rectangle with Width=5mm and Length=10mm. I now want to create a couple of sketches each increasing Length by 5mm.

An easy solution would be the have a formula for Length=10mm+X*5mm. X eqals 0 for the first case and is changed for every other sketch. X would here be the local variable that would be unique for each sketch. 

In the simple example above for sure the fastest way would be to create every sketch seperately but for sure my final sketch is more sophisticated and a lot of variables would have to be changed if done manually.

Outlines will not work as the dimensions change not all equal in all directions.

I also do not want to create multiple projects etc, multiple parts within one assembly would be ok.

If I have to change Width all parts should be updated accordingly without manual adaption.

Question:

Is there a way to create sketch specific parameters?

If not is there a way to create multiple parts, where you change a multiplier paramter specific for this part?

Thanks in advance for your help! Hopefully theres an easy solution that I'm not aware of or I'm simply overthinking and stuck 😄

Cheers,

Peter

Hi,

please share your design to take a look.

Thx for the reply.

I will try to share an example later the day, but actually as this is a very basic question and could be discussed by the Length of a single line itself, I don't think that it will help much.

Basically I'm just searching for a solution to create sketches/parts in different sizes without repeating to create all user variables or breaking all links to the core model.

like I said (now with a single line as example):

Core model has core_length of 10mm, every size (in a new sketch/part) larger it should be 10mm+Xmm.

I can do this by copy&paste of my model and set a new user variable to core_length+5mm, copy&paste again and do core_length+10mm etc for each size.

As this is (due to lots of sizes and many variables) a lot of effort. Also I don't want to break links between core model and different sizes as there might be changes in the core model. I could reduce effort by: core_length+X*5mm for all sketches/parts, where X is my size indicator .

But X needs to be unique for each sketch/part. Is this possible?

Maybe if I speak of global and local variables it might get clearer (sorry for the bad explaination)

I want to have a global variable/parameter/formula like Line_Length= 10mm+X*5mm, where I can specify X for each different sketch/part size as a local user variable (e.g. size 1: X=1 -> 15mm, size 2 X=2 -> 20mm)

Cheers,

Peter

Have you had a look at Sheeter? It might do what you want.

Have you tried using Derive > Parameters? What you describe is very close to global parameters, or even just a derived body/component.

Derive concept:

Thanks all of you for your replies. Unfortunately none of them can do what I need e.g Derive is lacking the possibility to have a unique parameter without breaking the link to the original.

Nevertheless I used Parameter I/O as a workaround. I created all functions, copied the sketch (doubling the parameters), exported the parameters, used an editor to replace the unique variables and re-imported them.

Thanks for all the help 🙂

I just assumed you would add the unique variable manually in the derive-consuming parts. Global parameters and local parameters.

I'll check out your workflow, it sounds interesting. I like what you are going for here.
