Scale model

Hi there,

I am pretty new in the 3D printer area and shapr3d world. Have tried some other tools, but this one seems to be the best for me.

I have designed a simple divider for a lunch box. Attached a picture. AFAIK, the model now contains many planes, lines and radii. I would like to get to a state where I can combine all elements to a final “solid” model and be in the position to scale it. E.g. the lengths over all is currently under investigation and needs to survive a field test :slight_smile:

So im am looking into a quick solution to play with the overall length of 114 mm today.

Thanks for your help!

I would suggest parametric approach. The form is quite simple so it can be easily parametrized.

Thanks.

Could you guide me with some points through the process?

Draw a sketch. Something like this one:

Two extrude operations and we have:

From this point you can change any sizes and model will change accordingly:

Also I would make this part like this.

But it’s just mine vision.

Great! Thank you.

Now some more questions appeared. I understand that I start new, which is fine for me. But

  • How do I setup, that this model is a parametric model? Is this automatic?
  • Did you sketch the shape as rectangular and later added the radii in the corners or did you do it with single elements like lines and bows?
  • Did you do the offset as a second sketch or “semiautomatic” by the offset function? If so, how did you approach that not the whole shape is being extruded?

Thanks again, Frank

You don’t need to set up anything. The parametric approach is more like a way of thinking — you model things as if you’re planning to change them in the future, so you plan how each part will behave in relation to the others.

That doesn’t matter at all. You can do it either way and get the same result.

Also doesn’t matter. Offset is a slightly faster approach, but you can do it as another sketch part and just set the constraints.
When you do the extrusion, you’re selecting a profile — just don’t select the whole shape if you don’t want to extrude it as a single piece.

So, I setup the model new. With some changes and w/o doing some corner round to make it more smooth.

How did you now get to the point to scale it. I do not find.

If you are at a point where you want to scale it, just use the scale tool.

Second icon on the left, or S on the keyboard.

Open the sketch you’ve used to create the model and change it.

Thanks to all.
I think I found it now. I am using the German version.

There are 2 options in scaling, uniform or non-uniform, if my translation is correct. Going to non-uniform, I can select the dimension and the scaling factor.

But I do not find the possibility to scale to fixed values (lengths, heights, etc.) like shown above in the video. How can I activate this?

Thanks

I already gave you the answer in my previous message.

What Alex describing is redimensioning or reconfiguring your model. To meet what ever spec you are working towards.

Scaling is just making things uniformly (or ununifimly) bigger so they are done in like 1.0000x or 2.000x (200%) as an example. If object was 114mm wide if you input 2x now it becomes 228mm wide it’s not done by actual height or width dimensions you need to do that math on your own or your use the built in calculator.

The Video from Alex does show different. He is not changing a scale factor, but actual dimensions in mm.

Did you read this part of my message?

I did, but maybe lost in translation (or elsewhere).

Alex model is 3D like mine. If I click on „Sketch“ at the right history bar, I get the picture like shown above.

Maybe my problem is just to unhide or display the measurements/dimensions like in his video?

Thanks

If all else fails just make a brand new model! :smiley:

Based on new and old measurements.

Yes. Thanks an to all, I learned alot.

But is there a button to hide/unhide dimensions?

In sketch mode

Via search:

But before showing dimensions you need to set them. If you’ve never assigned dimensions to your sketch parts you won’t see anything.


I would strongly recommend you to read manual.
