How do i edit this drawing so i can change the dimensions of an already made linear rail? basically i want to change it from a 15mm rail to a 20mm ect but when i change the dimensions it messes the drawing up shown in pic below.

I'd guess the outline is insufficiently constrained? It should be warning you that the shape is not completely defined.

i only know the basics of solidworks so i have no clue on how to work around that lol :) i can edit ball screws just fine but linear rails are a nightmare

Edit the sketch, select the profile, right click and Make Block. It should be possible to scale the block. If you have problems using the sketch at a later time, you can explode the block again.

Hope it helps.

just use Scale

In the Search box in top right corner type Scale then click on it. This will allow you to scale the model.

thankyou dean i know im being a nuisance. i actually managed to change the dimensions using the original model as it turns out once ive changed the dimensions once i no longer can re edit that file so i have to revert back to the original one.
