Quick way to find middle point of multiple objects

Code_x — Sat, 11 Sep 2021 17:19:47 GMT

Hello, is there any way to find middle a point for selected multiple objects ? Making blocks, creating groups or drawing a reference line is a slow process. If I could find a middle point by selecting multiple lines that would be very efficient, any advise would be very helpful,

Thanks.

In LT the methods you mention as being slow are really the only options. Any possible quicker methods would only be available through automation which you could find in the full version (and then only with custom programming).

If you need to draw something between midpoints why not use the MIDPOINT snap?

I think you missed the key words "multiple objects".

No I saw that, but if he's drawing an object between the midpoints of multiple objects midpoint snap will do the job.

That would be neat to see in action. AFAIK, midpoint is applied to a single object. Is it a new feature?

Draw using a polyline and you can just click on each midpoint.

I think you need to read the first post again.

"find find a middle point by selecting multiple lines" Is what you already did with your screenshot: perhaps you mean to do more than "find", but you need to explain that with more words, no one here understands your goal needs,, they are just guessing.

I can see middle point for each selected individual line that’s not a problem. What I normally need to do is to quickly establish middle point for these set of lines or objects, sometimes it could be an ornament or it could be bunch of furniture blocks. I need to select those and move somewhere else but I need to know where the center for those multiple selected objects is so that I can move that around, is it clear now what my goal is?

A closed polyline centre can be found with the GEOMETRIC CENTRE snap.

The mid point of a group of objects can be found using the MID2P snap and choosing the midpoints of the objects at either end of the selection.

How accurate do you want it to be?

If it's just an approximation, you could use the M2P (mid between two points) OSnap as your basepoint. It will get you as close as drawing a line and using the midpoint.

for lines and Plines (and ARCs), using the MIDpoint running ObjectSnap is the way https://www.cadtutor.net/tutorials/autocad/object-snap.php

For other objects or points where you need to select the midpoint between them you will have to use the more involved M2P (or MTP) method https://knowledge.autodesk.com/support/autocad-lt/learn-explore/caas/CloudHelp/cloudhelp/2019/ENU/AutoCAD-LT/files/GUID-04C9F013-46A3-430E-A085-BF254EA6B1D6-htm.html

To keep what you selected active when you move those areas offscreen you need to be using a modern version of AutoCADLT and have the SELECTIONOFFSCREEN variable turned on https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/Objects-not-in-view-deselect-when-adding-to-selection-set-in-AutoCAD.html
