In this file i want to make a door frame using follow me tool. I make a surface in plan and then i draw the path like a upside down U .. my desired height is for example 210cm
but when i use follow me tool ; the height of door frame that is made ; in each side (inner side of the door and outer side of the door) is different .. for example inner side is 209cm and outer side is 211cm
You could increase Display Precision in Model Info>Units. Also, you should turn off Length Snapping as that can actually create issues related to precision and accuracy.
If you are expecting symmetry between inside and outside you need to draw the profile that way.
As I wrote, increase Display Precision (I’d use millimeters instead of meter with more places to the right of the decimal) and turn off Length Snapping.
Here I’ve modified the profile so the casing will be the same on the inside and outside of the door.
The cad file is correct and the profile is not symmetrical .. my problem is the height in inner side and outer side will be different. the height is different.
The should be different because of the difference in the profile on the inside and outside. Follow Me is doing exactly what you are telling it to do. If all you want is the height to be the same on the inside as the outside, you can use Push/Pull on the top to adjust it but it will also change the width or the molding across the top.
Follow me is just extruding the profile along the path. If the two flanges are not the same depth on the sides, they are not going to be the same depth on the top either.
i can correct the height by using push/pull tool as you said and the problem will be solved. the length and width have no problem on the top. but still i don’t understand why follow me extrudes the surface with different height.. thanks
The cross section of the extrusion through the horizontal part at the top will be identical to the profile you started with. I don’t know why you would expect it not to be. Since you don’t want it to be the same, you need to make an adjustment after the Follow Me step.
To be honest, I don’t think it’s appropriate to pull the top up because it means the horizontal piece of molding is wider than the vertical ones and would require that the miter angle is not 45°. If I was the trim carpenter I’d be very irritated by that design choice.
