Make Your Models Adjustable
Ever printed something and wished it was just slightly bigger? Or wanted to put a different name on a keychain without asking for a whole new design?
That's what parameters are for. They turn a static 3D model into a customizable tool.
Instead of getting one fixed shape, you get a set of controls: sliders, text boxes, and switches, that let you tweak the design in real-time.
This also means you don't need to spend another generation every time you want a small change. Resize, relabel, or reconfigure your model as many times as you want, all without using up a single extra credit.
The Cheat Sheet
You don't need to learn code to get these controls. You just need to use the right words when you talk to GrandpaCAD.
Sliders (Numbers)
Perfect for sizes, lengths, or anything you want to measure.
Short Text
Great for name tags, signs, or personalized gifts.
Switches (Checkboxes)
Use these for optional things. Want a lid? Maybe some screw holes?
Dropdowns (Select)
Best when you have specific choices, like 'Circle' vs 'Square'.
Long Text
For longer text like descriptions or messages.
Try It Yourself
Here is a live demo of what these controls look like inside the app. Go ahead, mess around with them!
How to Ask
It really is as simple as chatting. You can combine these in one go.
"Hey Grandpa, make me a storage box. Give me length, width, and height number parameters so I can resize it. Also add a label text parameter on the side."
GrandpaCAD will pick up on those keywords and build the controls for you automatically.
Pro Tip: Keep it Organized
If you are making something complex with lots of settings, you can ask to group them.
"Put the size settings in a Dimensions group and the decoration settings in a Style group."
This keeps your control panel nice and tidy. Give it a try on your next idea!
