Perpendicular Dimensioning

[arch_08]

It would be very helpful to have the option to dimension perpendicular to a line, polyline, or similar element, as this would save a considerable amount of time.

I'm not sure if there's another shortcut, but currently, our workflow involves drawing a line perpendicular to another element, placing a "guide line" there, deleting the temporary line, and then placing the dimension. This is quite time-consuming.

If you don't delete the temporary line, the dimension remains linked to it and will disappear when you remove the line.

In any case, please add the ability to dimension perpendicular to a 2D element. Thank you.

It will never be an associated dimension unless you add a node at the perpendicular point on the line.

You would also have to adjust the position of that point if elements move.

You can do it with just the temporary guidelines, no need to draw a line and then a guide line.

Activate the guide node and guide line before you start the dimension, because it is harder to place the node guide while dimensioning.

I will leave the wish active, because it would be nice to be able to do it by clicking the first point of the dimension, then activate the guide line and dimension perpendicular to it.

Currently you have to establish the guide node as well.

Thank you for your reply.

I had no idea you could do it that way. I still don't quite understand exactly how you did it, but I've now realized you can use "Guides > Create Guide Line Segment" and draw a guide line only for that part, without an additional line. Is that what you had in mind?

We've always drawn guide lines by dragging from the side. 😊

Otherwise, it wasn't meant to be an associated dimension. It was more in the sense of automatically drawing a "guide line" that would allow you to dimension perpendicularly. Similar to what AutoCAD has probably had for 20 years.

Thanks again for your answer.

I'm referring to the blue temporary snap guides.

They disappear as soon as you complete a command.

Unlike the orange guidelines you drag from the side - you have to delete those manually.

Oh my god, I had no idea that works! I feel so stupid right now 😬

I've been using it for ages, and it never worked. The problem was I wasn't waiting long enough at the first point. If you wait long enough, it works exactly as it should.

You can delete this wish now 😁

Thanks again

You can force snap guides with a keyboard shortcut ... q or `

You can also set the delay time for the guides to activate in the Work Environment.

You don't want them too quick - they get annoying.

I think 1 second is the default.

Any longer is fine but then you need to use the shortcut to activate.

Thanks. I'm using snap guides, and it isn't an issue that I have to wait. I just didn't know that if a guide node appears, you can draw a line perpendicular to another line.

Now I better understand what you meant in your first post. And yes, I agree it would be easier and more intuitive if this option appeared even without activating a guide node first, but also just by clicking a point.
