Hi,
I have downloaded a moldel(part) that has it's dimensions specified by smart dimensions. I like to remove some of them and modify the model but when I select them and clicking on delete key, it doesn't work and I only can change the dimension number! but I like to delete this dimension restriction! How can I do it?
Did you edit the sketch and then try ?
Did you try turning off "instant 2D" if you are using SOLIDWORKS 2016 or higher. Or click the arrows, not the number and hit delete ? I.E. if you are double clicking it.
If it's sketch dimensions you will need to edit the sketch, then you should be able to right-click on any dimension (even with Instant 2d on) and select Delete from the drop-down. If it's a feature dimension, such as the length of an Extrude, then you'll need to edit the feature. You won't be able to delete it, but you can edit it, or delete the feature.
Moled= Model!
