Is it possible to add constrain to different layer of sketches?

Hi, I am new to s3d. I am just countering 1 problem. I love the idea of building everything with histories, I believe s3d engine use every step of the history to build up the model so that we can adjust the sketch to make effect to the model immdediately.

However, is there any reason why we can’t add constrain between different layer or even different dimension of sketch? Lacking of this feature makes the body/sketch in other dimension can’t fully connected with the original sketch.

Here is my ideal imagined use case, e.g…
I am building a house by sketching the floor plan first. After I extruded the wall, I would like to add a window horizontally at the center of the wall. Without the feature to add constrain across layer, I can’t connect the mid point of the window to the mid point of the wall. Ideally, I think I could enlarge the window when I enlarge the floor plan if we can connect the sketch between 2 layers

You can project those lines onto your wall layer as construction lines. Than you can see them while editing the wall

Hi @pHp, Thanks for answering. However, I don’t think this can really solve the problem. What I want to achieve ultimately is that when enlarging my wall, the window will also move itself back to the horizonal center of the wall

Hey, so I’ve reread your question. This my idea will work to let you see where the lines are. If you want the constraints so that they resize correctly you just have to create your new square and then, instead of setting the dimensions of the square you set the dimensions from the outside wall. For example I’m designing new kitchen cabinets right now and I want all the drawer faces and door faces to sit in inch and 3/4 from both top and bottom and an inch and a half from the walls. So I modeled my cabinets and extruded them, and then I sketched on the face of the cabinets , a rectangle and then determining the size of the rectangle I can set it edges to be an inch and a quarter from the top and an inch and a half from the left and right and then between my drawer box and my door I also cainstrained an inch and three-quarter gap. by doing this I put zero dimensions for the drawer and the door cut, but those still ended up at the exact measurements. I need it to be knowing that If I resize my box the drawer always remain an inch and a half and an inch and three-quarter from the top and sides.

heres a video i do hope it helps. i think for your window, instead of locking the distance to the outside line. you could make a construction cross at the middle of your window and set the distance from there so tha the window can never leave that size, no matter how big the wall

Hey Thanks @pHp. Helped me a lot.
Btw, your voice is amazingly charm

Hahaha thank you and not a problem!
